POWER “Roll Checker” assures easy and accurate measurement of various parameters through flow path of casting roll stand which directly affects the quality of casting slab. The measured parameters such as roll gap, roll alignment, roll rotating condition and water spray nozzle, are collected and stored in board computer and transferred to host computer for analysis. Each system is custom designed to fit the casting plant requirement. The Roll Checker is designed to maintain durability and accurate function under severe environment. Full automated system, developed by POWER MnC, is most advanced against the existing ones.

As the demand for high quality slab with higher productivity increases, the more strict control of pass line is required. Since the ICSM run as a part of DB chain, it can measure the strand condition at every casting without downtime of the caster which was inevitably required for the DB head replacing type measuring monitor. POWER MnC has supplied ICSM which can automatically operate without any manual manipulation from start-up with DB chain feed-in, measuring, data storage and analysis, measured data base management, battery charging and ready for next operation. Of course, it guarantee the measuring accuracy level as high as that of the conventional type. The highest quality and productivity of CCP in NSC, Japan and POSCO, Korea is much indebted to the In-chain type Caster Strand Monitoring system which is called as ICSM or MM(Machine Monitor) by NSC and ORGC(Online Roll Gap Checker) by POSCO.

Mould Oscillation Monitoring System

While the liquid steel is poured in, the mould has to perform an up-and-down oscillatory motion to keep friction between the solidified product surface and the mould walls under a critical limit. Since Oscillation of the heavy mould is usually generated by a powerful eccentric driver or hydraulic actuators, in case of wear, unwanted mould oscillations in transverse direction may occur which may affect the quality of the produced strand. MOM-2000P can measure the oscillatory trajectories in x, y and z space. The synchronized signal analysis by using multiple sensors (maximum 4 for slab mould, each per a corner), the oscillatory trajectories of each corner of a mould can be shown in 3-D graphics, of course, phase shift report generation, which can give a clear direction for maintenance of the actuating system.

In continuous casting process, the preset taper angle of the mould

should be checked before casting start because the Incorrectly set

taper angle of the mold walls can cause quality troubles of the product

surface.

The taper angle of mould walls in continuous casting should be kept

correct as per the cross-sectional dimension and chemical composition

of the casting product considering volume shrinkage ratio of the melt

steel through solidification. Especially air trapping should be prevented

for safe operation of the caster against break-out accident as the worst

case. The Portable Mould Taper Measuring System(PMT-2000) can

be used for highly accurate measurement of mould taper at continuous

casting with lots of user-convenience design -light weight for easy handling,

-quick measurement setting regardless of the mold condition,

-large and digital display of the measured results and

-convenient calibration by test stand

Measured value of the inclined angle of the mould wall can be

converted to length dimension as per the corresponding mould depth

which can be adjusted by changing the setting value.

For slab mould case, PMT-2000 can measure both directions of

thickness and width by self-supporting wing without any help of extra

jig/fixture.

For billet mold case, non-contact type laser sensor can measure the

mold width in x,y both or each directions at each step of z(depth)

direction, the measured profile of billet shall be displayed in 3-D graph

for quick review of the customer. For Slab For Billet

Weighing System for Steel mill

Ladle Slag Detector (LSD)

The Ladle Slag Detector can pick the carried-over slag particles towards the end of teeming. Because LSD responds to small amounts of slag particles entrapped in the molten metal, it enables the operator to take action before the carried-over slag can be detected through his experience. An electromagnetic measuring method is used to detect slag flowing into the molten steel. Eddy currents are induced from coils arranged concentrically around the tap tube and the electromagnetic fields are measured. Slag has an electrical conductivity that is lower than the molten steel. Therefore, being slag in the molten steel, the conductivity changes and the magnetic field also changes. Finally LSD measures this change.

Since the weighing systems in steel mill are used as very important process chain, it must be guaranteed to work safely, accurately and reliably in harsh operating environment. Based on the utmost knowledge of force measuring and its instrument (load cell), adding plentiful experiences of the industrial sites, POWER MnC supply any kind of weighing system; from the sensor itself (both strain gauge type and magnetic type load cell) to total system. -Blast Furnace weighing system -Toepeido car weigher -Ladle/Tundish weighing system -Scrap weighing system -Slab weighing system

Magnetic type load cell is used for weighing/force-measuring sensor for key equipments in rolling process automation. The measurement principle of Magnetic Load Cell is based on the magneto-elastic effect (Villari effect), in which the permeability of the ferromagnetic material is changed due to the external mechanical force. By combining the environmentally robust characteristics of the magnetic load cell and plentiful experience of steel mill experience, POWER MnC supply the measurement equipments and system for rolling process as well as the magnetic load cell based measuring sensor. Maximizing the beneficial characteristics originating from magnetic type load cell, it shows • Extremely robust against harsh environmental condition • Rigid frame having no deformation characteristics against

heavy load • Overload ratings are as high as 15 times the rated load. • Produces high output signal levels. With wide range of application as; • Roll force measurement in rolling mills. • Strip tension measurement in rolling mills. • Weighing crane in steel plant. • Shapemeter for Flatness Control

Automatic Flatness Control for Rolling Process

Magnetic Load Cell for Rolling Process Automation

POWER MnC ‘Shapemeter’ provides full data about ‘flatness of strip’ by measuring the internal stress distribution of strip in cold rolling mill. The measurement principle is the same as Magnetic Load Cell. Unlike optical type sensor (non-contact method), ‘Shapemeter Roll’ directly contacts with strip. So, ‘Shapemeter’ measures the internal residual stress of strip. • Extreme reliability • Supreme accuracy • Insensitive to tension transients caused by roll or coiler eccentricity. • 4 measurements output per a roll revolution • Long term stability • The entire strip force on the roll is measured.

Shapemeter

11

It’s essential to keep the tension constant in strip processes for high product quality and productivity. In order to achieve real and accurate measurement of strip tension, the overall part and system should be design-and-installed in correct way, including the measuring sensor as well as surroundings and installation. Load cell for tension control should be designed environmentally protected against the harsh mill conditions such as impact, vibration, dirt, humidity and corrosive environment. POWER MnC’s load cell, putting a premium importance on long-term operation reliability, is made of stainless steel for intrinsic corrosion prevention. The ultra-high spring constant of the sensor block of the magnetic load cell ensure best mechanical performance with no physical deformation, high overload protection and insensitive to vibration property.

Strip Tension Control

12

The truly measured roll force at each side of rolling mill stand is essential for correct roll gap settings for uniform thickness strip processing. Combining thousands of magnetic load cell, the ultra-high capacity Roll Force load cell can be designed, the shapes of which are 3 types physically complying to the installation space as; the Rectangular shape is under the lower back-up roll bearing, Circular one is under the mill screw, and the Annular type is installed between the mill nut and the mill stand. The ultra-high spring constant of the sensor block originated from the stacked magneto-elastic laminates enable us to design over 60MN capacity Rectangular/Circular type load cell for the limited installation space.

The Korean Nuclear Power Plant was launched from Kori Unit 1 of 600MWe class in 1978. Twenty units have been constructed in the past three decades. As a result, six units of 600-700MWe class and fourteen units of 950-1000MWe class are now in operation. The construction of four additional units, which are 1000MWe, was recently initiated. The Korean nuclear industry achieved technology self-reliance through this excellent performance and the Optimized Power Reactor 1000 (OPR1000), which was formerly the Korean Standard Nuclear Power Plant (KSNP), has been constructed. To improve public acceptance and enhance economics, Korea has been continuously developing a new reactor model for a long time along with the improvement of OPR1000. As a result of such an effort, Korea developed the Advanced Power Reactor 1400 (APR1400) as a Korean national R&D project spanning ten years and the standard design certification was issued in May of 2002. The APR1400 is an evolutionary PWR (Pressurized Water Reactor) with a thermal output of 4000MWth. As the manufacturer of the Fuel Handling System, POWER MnC constitutes a key part of the supplier chain of APR1400, the 3rd generation NPP with revolutionary enhanced safety.
