SMS Siemag supplies the castingfloor, moulds, hydraulic oscillator,strand guide system, edge-con-trolled secondary cooling and posi-tion-controlled segment gap adjust-ment as well as the pinch-roll unitsfor the dummy bar and hot strand.The complete X-Pact® electrical andautomation system is also includedin the supply. The continuous casteris equipped with the proven techno-logical systems for mould-level con-trol, hydraulic oscillator, hydraulicsegment gap adjustment withdynamic soft reduction and loadcompensation control. In coopera-tion with the department of DillingerHütte, SMS Siemag has developeda hydraulic adjustment system forthe pinch rolls specially for this con-tinuous slab caster.

Use is made of dynamic soft reduc-tion for the diameter range in ques-tion to manufacture semifinishedproducts with optimized internal qual-ity. This involves pressing the strandshell together during casting in such a

way as to enable the material proper-ties to be homogeneous right intothe core.

The adjustment mechanisms other-wise customary in continuous cast-ers will be extended by a furtherdimension on the basis of experi-ence gained with rolling technology.The result will be a further enhance-ment of the soft reduction rates, asimplemented successfully for theCC5 in Dillingen.

In conformity with the customer'sspecifications, the vertical externalwalls of the deep parts of the foun-dation are not, as otherwise usual,

built on a rectangular ground-planarea but on a circular area.

The self-supporting effect of thiscross-sectional layout makes it possi-ble to do without costly and time-con-suming horizontal anchors, whichmakes it easier to perform the workon site. The design of the CC6 essen-tially corresponds to that of the CC5continuous caster. This results in sub-stantial synergy effects for operation,servicing and maintenance.

The commissioning of the two-strandvertical-type continuous caster isscheduled for spring 2014.

The thickness re - duction (Liquid Core ReductionLCR®) and width adjustment werealready successfully utilized whilecasting the first sequence.

Essar Steel can produce hot stripwith widths of 950 to 1,680 mmand thicknesses of 1.0 to 25.4 mmon the CSP® plant. The productrange covers carbon steels as well

as pipe grades, silicon and dual-phase steels. The CSP® processoffers the best prerequisites for theeconomical production of high-qual-ity steel grades.

SMS Siemag's scope of supplyincluded the engineering, the manu-facture of the mechanical equip-ment, the entire X-Pact® electrical

and automation system, as well aserection and commissioning super-vision.

The CSP® plant with the first strandwas put into operation on 31 March2011, the third strand will be installedin 2012. Essar Steel will thus havethe first three-strand CSP® plantworldwide with an annual capacity of 3.5 million t of hot strip.

JINDAL SOUTH WEST LTD.JINDAL SOUTH WEST LTD.India

Steep run-up curves, professional cooperation: three continuous

casters in three years

Jindal South West Steel Ltd. in Toranagallu in the Indian federal state of Karnataka awardedSMS Siemag contracts for the supply of two converter meltshops and three continuous slabcasters. One continuous caster each was commissioned in 2009, 2010 and 2011.

The three continuous slab castersare of identical design, which makesthe stocking of spare parts and thusmaintenance of the units much morecost-effective. The casters are eachrated for the production of 220, 260and 300 mm thick slabs. The widthsare between 1,000 and 2,200 mm.

The equipment of the castersincludes several Intelligent SlabCasting (ISC®) modules whichdetermine quality and production.Among these are the hydraulicallyoperated resonance oscillation sys-

These grades, which account for ashare of more than 50% of the totalproduction volume, have alreadybeen successfully cast to slabs.

This high monthly production ratewas supported by the reliable func-tioning of the Breakout PredictionSystem (BPS). It detects "stickers"in the mould and prevents thepotential breakout by considerablyreducing the casting speed. Oncecasting operations have stabilized,the speed may be raised to its for-mer maximum level again.

Since the end of January 2011, theDSC (Dynamic Solidification Con-trol) has also been in operation. Thismetallurgical process model calcu-lates the solidification process ofthe strand and controls the varioussecondary cooling zones. Especiallycrack-critical grades must be con-trolled at exact temperature levelsby the bending and straighteningzones of the continuous caster inorder to minimize flaws locatedclose to the surface. The commis-sioning record dated January 2011certifies that "the surface quality ofall grades is excellent".

At the end of March 2011, the thirdcontinuous slab caster was success-fully commissioned in meltshop no.2, its acceptance was granted byJindal South West in June 2011.

vision and training of the operatingpersonnel.

All modules have been in operationsince the respective commission-ing. This was made possible by thecooperation among the well-trainedoperator crews from JSW and theexperienced SMS Siemag commis-sioning specialists from India andGermany.

PEINER TRÄGER GMBHPEINER TRÄGER GMBHGermany

Germany's first combination caster for beam blanks and slabs

At Peiner Träger GmbH in Peine, SMS Siemag has revamped a two-strand continuouscaster for beam blanks into a combination caster which can now also produce slabs. Thefirst slabs were cast in February 2010, after a change of section size also beam blanks. Thetwo-strand combination caster is now rated for the production of 250 mm thick and 500 to1,100 mm wide slabs and for size 1,150 mm x 490 mm x 130 mm beam blanks.

Continuous Caster No. 2 of PeinerTräger is the first combination casterin Germany for casting of beamblanks and slabs. The world's widestbeam blank size is produced on thecaster.

The scope of supply of SMS Siemagcomprised all strand guiding compo-nents required for the continuousslab caster, the slab mould as well asthe X-Pact® electrical and automation

package including the technologicalprocess models. Pinch roll units 3and 4 (driven segments 8 and 9)are used for all casting sizes, i.e. for slabs and beam blanks. They donot need to be changed when sec-tion sizes and shapes are changed. This reduces changing times andincreases production.

A design innovation of the beamblank caster is the ability to replace

segments 3 to 5 by the equipmentrequired for the blow-off deviceand the edge heater. In total, SMSSiemag supplied forty segments.

With the successful commissioningof an electric steelmaking plant thatwas also supplied by SMS Siemag,the annual production has almostbeen doubled while still meetingthe increased demands placed onthe steel quality.

Fourth continuous slab caster supplied by SMS Siemag at Salzgitter

Flachstahl - Central Europe's largest continuously cast section size

SMS Siemag AG has successfully commissioned the fourth continuous slab caster forSalzgitter Flachstahl GmbH (SZFG), Germany. The single-strand bow-type caster producesslabs ranging in widths from 1,100 to 2,600 mm and in thicknesses of 250 and 350 mm. Theslab dimensions of 350 x 2,600 mm currently represent the largest section size for continu-ous casters in Central Europe.

SMS Siemag's order scope com-prised the basic and detail engineer-ing, the supply of all mechanicalcomponents and the complete X-Pact® electrical and automationsystem, including the technologicalcontrol systems and process mod-els. In addition, the supply scopeincluded the solid structures andstructural steelwork, a new watersupply and treatment system aswell as the erection, commissioningand supervision.

Salzgitter Flachstahl uses the casterfor the production of highly demand-ing micro-alloyed steels, heavy-plategrades and sourgas-resistant tubeand pipe grades according to theAPI-5L and HIC standards.

In particular the 350 mm thicknessoption makes it possible to provideslabs for heavy-plate manufacture ina hitherto completely new range ofdimensions that are most attractivefor future requirements.

The equipment of the casterincludes several Intelligent SlabCasting (ISC®) modules whichdetermine quality and production.Among these are the hydraulicallypowered resonance oscillation sys-tem, remote-controlled mould nar-row faces for width change duringcasting and the position-controlledCyberLink® segments to performDynamic Soft Reduction. The pro-duction of slabs of a high internalquality is thus guaranteed throughthe above in combination with thewidth-dependant air-mist second-ary cooling and the technologicalDynamic Solidification Controlprocess model.

Also, in order to cast steel gradeswith critical crack susceptibility onthe continuous caster in a reliableand productive manner, themachine has been designed as abow-type caster with a constantradius of 11.5 m. This design mini-mizes stresses in the strand shelland achieves excellent surfacequalities.

Extract from the paper read by Dr. Markus Schäperkötter,Salzgitter Flachstahl AG, on the Steel Day 2011

In the production of sour gas resistant steel grades, a very largeshare of slabs without casting events (e.g., start-up, tundish change,end slabs) was attained. All HIC-tested (Hydrogen Induced Cracking) high-quality slabs werefound to be free from defects. By June 2011, out of a total of1,149,000 t, 610,000 t of steel were rolled to heavy plate, of which250,000 t were slabs with a thickness of 350 mm. The new continu-ous caster made it possible to almost halve the input stock-relatedplate failures for size 250 mm. The quality levels of the 350 mm slabsare also very good, the slightly higher level as compared to 250 mmis due to the higher thickness involved in the process. The very goodproduct quality is also confirmed by the numerous examinations ofthe internal quality of the slabs produced."

To reduce the stresses caused inthe boundary layer between solidi-fied and liquid steel, the caster wasrevamped from four-point straight-ening to 14-point straightening.Strand bulging and the stressescaused by this could be reduced byreplacing the existing five seg-

ments by segments with sevendouble-split roller pairs. In addition,each segment was equipped with a hydraulic segment adjustment,which allows the roller gaps to beadjusted online and thus DynamicSoft Reduction.

Positions 7 and 8:

Segments with

stationary side frames

Two basic segment types wereused in this modernization con-tract. Conventional segments withstationary side frames wereinstalled at the straightening posi-tions 7 and 8. On account of thereduced straightening forces thisarea of the caster now also allowsthe use of soft reduction. This isbeneficial for steel grades whichneed to be cast at lower castingspeeds and whose final solidifica-tion takes place at an earlier pointin the strand guide system.

Positions 9 to 11:

CyberLink® segments

with guide frame

CyberLink® segments were usedin the horizontal part of the strandguide system, segments 9 to 11.These segments have guide framesthat connect the top and bottomframe. This solution allows the toprollers to be adjusted as required.

The segments fit into the existingmachine structure without any problems. The existing foundationframes, the segment removal rails,the cooling chamber and the seg-ment drive units were re-used withminor changes. Maintaining the segment centerlines, the new seg-ments were adapted to the existing

supporting frames. A hydraulicallyoperated key/bolt system was usedto fasten the segments to the seg-ment carrying frame. Using adapterplates, the existing water pipeswere adjusted such that the pipesfor the supply of spray and machinecooling water are automatically con-nected to the new segments.

High productivity

Slab caster no. 7, CSC's fifth machine supplied by SMS Siemag, has an annual capac-ity of 2.6 million t. The two-strand caster is rated for a maximum casting speed of 2.2 m/min, casting slabs that range in width from 900 to 1,680 mm. The SMS Siemagsupply scope comprised the basic and detail engineering as well as the supply of allmechanical core components and the X-Pact® electrical and automation system,including the technological control systems and process models.

High flexibility thanks to

Intelligent Slab Casting®

The technologies installed by SMSSiemag ensure a higher productiv-ity plus perfect product quality andprovide maximum flexibility. Exam-ples are the hydraulically operatedresonance oscillation system andthe remote-controlled mould nar-row faces.

Constant product quality

The X-Pact® electrical and automa-tion systems control and monitorthe processes and the slab quality.The mould level control system(Level 1) prevents casting-flux inclu-sions and ensures a high surfacequality of the slabs. Dynamic SoftReduction® in the segments sub-jects the slabs to a defined pres-sure and thus avoids core segrega-tions and core porosities.

The result is a consistently goodinternal quality of the slabs. Simi-larly, the Mould Monitoring System(Level 2), which detects the tem-perature profile of the mould,serves for quality control and forthe prevention of breakouts.

Dynamic Solidification Control con-trols secondary cooling and thusensures that the required metallur-gical properties are achieved.

Fully developed systems

The precise construction of themechanical and SMS Siemag'swealth of experience ensuredsmooth commissioning and a faststart of production at CSC. Thecomplete automation system hadbeen tested and optimized before-hand according to the Plug & Workmethod in simulation mode at SMSSiemag. This made it ready forimmediate commissioning on site.

MAANSHAN IRON AND STEELCOMPANY MAANSHAN IRON AND STEELCOMPANY China

Two single-strand CSP®casters with Liquid Core Reduction LCR® plus

In 2003, SMS Siemag installed two single-strand CSP® casters at Maanshan Iron & Steel. The produc-tion capacity in the years between 2007 and 2008 was each around 2.3 million t of hot-rolled widestrip for the production of hot and cold strip.

In 2009, the two single-strand CSP®

casters were successfully modern-ized and are now equipped withLCR® plus. This technology pro-vides an extended thickness range from 90 to 60 mm (formerly 90 to72 mm) as well as a high utilizationof the strand guide length (metallur-gical length) of 9,705 mm. LCR®

plus is the result of research and

development work as well asindustrial-scale testing in close col-laboration between SMS Siemagand Maanshan Iron & Steel.

cover a final thickness range from90 to 50 mm. LCR® and Thermal Segment Tapering are performedby four hydraulically position-controlled segments which are infinitely variable.

Liquid Core Reduction

(LCR® plus)

The aim of cost-effectively produc-ing hot-rolled strip leads to evernew process sequences. Produc-tion stoppages to set the caster to a different thickness must beminimized. Since all strand guidesegments are equipped with infi-nitely variable position-controlledhydraulic cylinders, LRC plus,depending on the steel grade andhot-strip final gauge, allows an individual adjustment of the slabthickness.

LCR® plus allows the operator orproduction planning department topreselect a dynamic thicknessreduction from 1 to 35 mm. Thisallows minor thickness changes of1 to 20 mm to be set via segment 1 and thickness changes up to 35 mm via segments 1 and 2. Therolling schedule thus becomes a

great deal more varied. In bothcases the thermal shrinkage of thestrand that corresponds to the steelgrade is also automatically takeninto account in segment setting.

During casting with dynamic LCR®

plus, the positions of the segmentsare monitored and controlledonline. Flexible adaptations of thick-ness over the length of a slab canthus be precisely regulated andcommunicated to the HSM com-puter. Position control of the seg-ment takes into account the currentcylinder loads.

„Gao Hai Cao, Director ofsteelworks and rolling mill

"With LCR®, Maanshan Iron& Steel is now in a positionto flexibly roll all steel gradeswithin one sequence",explains Chen You Gen, Sen-ior Technical Manager of thesteelworks and rolling millno.1 Gao Hai Cao, director ofthe steelworks and rollingmill: "This makes the CSP®

caster of Maanshan Iron &Steel the world's first unit torealize a 30 mm liquid corereduction.“

In position control mode, the cylin-der loads are maintained at exactlyadjusted minimum and maximumlevels, so as to provide a perma-nent contact between the rollerand strand and to thereby protectthe segment from overloads. Thespecial travel algorithm of the posi-tion-controlled segments 1 to 4makes it possible to roll down thetransition pieces produced duringthe thickness reduction, withoutoutput and quality losses.

WUHAN IRON AND STEEL(GROUP) CORP.WUHAN IRON AND STEEL(GROUP) CORP. China

Two-strand CSP® caster for 2.5 million t of hot strip

On 7 March 2009, the first strip was rolled by the new CSP® caster at Wuhan Iron & SteelCorp. (Wisco) in Wuhan in the Chinese province of Hubei. For the two-strand CSP® casterSMS Siemag supplied the mechanical equipment and the X-Pact® electrical and automationsystem. At 10,000 t and 70,000 t, the production targets set for the first two months wereclearly exceeded. The Plug & Work concept is intensively used to prepare commissioning.All components of the automation system are set up and tested under near-real conditionsbefore commissioning.

Depending on the required finalgauge, the steel grade and cast-ing speed, the slab thickness isinfinitely variable from 90 to 70and 70 to 52 mm by means ofLiquid Core Reduction.

The production of the new plantfocuses on strip made from high-quality steel grades, includingsteels for the automotive industry,weathering-resistant steels, pipeand multiphase steels as well assilicon steels.

Wisco is one of China's major producers of silicon steels. Withrespect to the process involved,CSP® casters provide good condi-tions for the production of thesesteels.

This starts with the casting process:The thin slab solidifies at an earlystage and has a particularly homo-geneous microstructure with finelydistributed precipitations. Due tothe relatively high temperatures of

the slabs upon their entry in thefurnace, undesired precipitationsare avoided.

On entering the rolling mill, the thin slab exhibit a virtually constanttemperature over its width, thick-

ness and length. These conditionsallow a stable, trouble-free rollingprocess even in case of materialsthat are difficult to roll, with themechanical and geometrical prop-erties thus lying within close toler-ances.

The resonance oscillator, with variable oscillation frequency,stroke length and curve shape,guarantees that the slab surfacewill be of consistently excellentquality. This represents a consider-able cost benefit, above all whencasting stainless steels. In the res-onance oscillator, the mouldsweighing around 30 to 40 t oscil-late at a frequency of 1 to 7 Hzduring casting, to avoid that thesteel sticks to the cooled walls ofthe mould. In addition, this allowsthe specific placement of castingflux between the hot strand andthe mould's copper wall.
