CHANGING SCENARIO IN STEEL MAKINGAVAILABLE & EASY ACCESSIBLE OF RAW MATERIALSIF REQUIRED THE RAW MATERIALS CAN BE IMPORTED SCRAP DEMAND IS INCREASING CONTINUOUSLYSTEEL USERS ARE REDUCING IN SCRAP GENERATION SMALL SCALE STEEL MAKERS ARE INCREASINGSCRAP AVAILABILITY IS BECOMING LESS & EXPENSIVEMOSTLY DEPENDENT ON IMPORT – LEGISLATION???

POSSIBLE SOLUTION IS “DIRECT REDUCED IRON (DRI) ‐ SPONGE IRON”


DIRECT REDUCED IRON (DRI) ‐ SPONGE IRON

DRI / SPONGE IRON IS A SOLID HIGH QUALITY METALLIC PRODUCT OBTAINED BY DIRECT REDUCTION OF IRON ORE (HIGH GRADE) AT TEMPERATURE JUST BELOW THE FUSION POINT OF IRON

IT IS CALLED AS SPONGE IRON BECAUSE OF ITS SPONGY MICRO STRUCTURE AND ALSO KNOWN AS DIRECT REDUCED IRON (DRI),

ADVANTAGE OF DRI / SPONGE IRONEICS INTERNATIONAL LLC

USING AVAILABLE MINERALS TO PRODUCE STEEL

ANY TYPE OF ALLOY STEEL INCLUDING CONSTRUCTION STEEL, AUTOMOBILE STEEL CAN BE PRODUCED

COST OF PRODUCTION IS LESS

CAPITAL INVESTMENT IS LESS

PLANT CONSTRUCTION TIME IS LESS

USER‐FRIENDLY PRODUCTION PROCESS

POWER GENERATION FROM WASTE HEAT RECOVERY SYSTEM

USE OF SOLID WASTE (UNBURNED COAL) FOR POWER GENERATION USING FLUIDIZED BED COMBUSTION BOILER

THE BENEFITS OF DRI OVER SCRAP

HIGH DEGREE OF METALLIZATION AND QUALITY METALLIC PRODUCT WITH 82 TO 92% METALLIC IRON CONTENT

LOWER COST COMPARED TO SCRAP

IT'S FREE FROM ELEMENTS LIKE COPPER, ZINC, TIN, CHROMIUM, TUNGSTEN AND MOLYBDENUM ETC WHICH ARE USUALLY PRESENT IN SCRAP

FIXED CHEMICAL COMPOSITION IMPROVES EFFICIENCY IN ARC / INDUCTION FURNACE

LOW % OF IMPURITIES LIKE SULPHUR & PHOSPOROUS


THE BENEFITS OF DRI OVER SCRAPALMOST NON‐EXISTENCE OF ELEMENTS LIKE LEAD & COPPER

SUITABLE SIZE, RANGE AND SHAPE

EASY FOR HANDLING AND STORAGE

HIGH DENSITY FOR FIXED VOLUME

DRI CAN BE CHARGED WITH SIMPLE CHARGING SYSTEM

POWER CAN BE GENERATED FROM WASTE HEAT • 2.0 MW from 100 TPD CAPACITY ROTARY KILN• 8.0 MW from 350 TPD CAPACITY ROTARY KILN • 12.0 MW FROM 500 TPD CAPACITY ROTARY KILN


DRI ADVANTAGES IN EAF / IF CHARGE MIX

CHEMICAL COMPOSITION OF DRI IS UNIFORM

DRI PERMITS AUTOMATIC CONTINUOUS / BATCH CHARGING

IT HELPS TO CREATE A FOAMY SLAG

FASTER MELTING TIME

LONGER REFRACTORY LIFE

IT CONTAINS VERY LOW LEVELS OF UNDESIRABLE METALLIC IMPURITIES IN THE FINAL PRODUCT,

LESS NOISE OCCURS DURING MELT DOWN WITH DRI THAN SCRAP



DRI ADVANTAGES IN EAF / IF CHARGE MIX

IT DOES NOT REQUIRE DE‐SULPHURISING AND DE‐PHOSPHORIZING PROCESS IN ELECTRIC ARC FURNACES

MELTING OF DRI IN EAF / IF IS GREATLY INFLUENCED BY FACTORS LIKE CARBON CONTENT AND DEGREE OF METALLIZATION OF DRI

ENHANCED STEEL QUALITY ‐ IMPROVED QUALITY IN THE FINAL PRODUCT

IMPROVES CONSISTENCY OF THE PRODUCT QUALITY,

MECHANICAL PROPERTIES OF STEEL ARE IMPROVED PRODUCED BY USING DRI IN THE CHARGE MATERIAL


WASTE HEAT RECOVERY

FROM

ARC FURNACE EXHAUST HEAT


TO RECOVER HEAT ENERGY FROM SCRAP MELTING ARC FURNACE EXHAUST WHICH IS GENERALLY WASTED TO ATMOSPHERE AFTER FORCED COOLING.

TO COVERT THIS ENERGY INTO USEFUL FORM LIKE ELECTRICITY WHICH CAN BE CONSUMED BY USER CONTINUOUSLY.

REDUCE OPERATING COSTS FOR PRODUCING / PROCURING THESE UTILITIES.

IN THE ARC FURNACE THE INPUT CHARGE IS LOADED AND ELECTRODES ARE INSERTED AS REQUIRED BY THE PROCESS.

LOT OF HOT GASES ARE GENERATED IN THE PROCESS OF METAL MELTING & THESE GASES ARE PULLED THROUGH A WATER COOLED DUCT WITH THE HELP OF AN I.D. FAN.

BAG FILTER IS PROVIDED TO REMOVE DUST PARTICLES WITH INLET AIR BLEED ARRANGEMENT.

MAJOR PART OF HEAT IS REJECTED TO ATMOSPHERE THROUGH COOLING TOWER AND BALANCE IS REJECTED THROUGH I.D. FAN EXHAUST.

THIS HEAT ENERGY IS WASTED WITHOUT ANY UTILIZATION.

THE PRESENT SYSTEM


THE HEAT PRESENTLY BEING WASTED TO ATMOSPHERE WILL BE USED FOR GENERATION OF MEDIUM PRESSURE STEAM

THIS MEDIUM PRESSURE STEAM WILL BE SUPPLIED TO A CONDENSING MULTISTAGE STEAM TURBINE GENERATOR TO PRODUCE ELECTRIC POWER

CONDENSATE FROM CONDENSER WILL BE RECYCLED TO BOILER.

NEW SYSTEM WILL BE INSTALLED IN PARALLEL WITH EXISTING SYSTEM WITH A DIVERTER VALVE

THE FURNACE CAN WORK WITHOUT ANY PROBLEM EVEN IF THERE IS ANY MAINTENANCE ON NEW SYSTEM

THE CONCEPT OF NEW SYSTEM


THE CONSTRAINTS / CRITICAL AREAS

THE ARC FURNACE IS A BATCH TYPE OPERATION AND HENCE THE WASTE GASES ARE NOT AVAILABLE ON CONSISTENT TEMPERATURE AND FLOW

THIS WILL AFFECT THE CONTINUITY IN STEAM GENERATION

STEAM TURBINES NEED STEADY PRESSURE AT INLET

THE BOILER HAS TO BE SUITABLE FOR HIGH DUST LOADING OF UPTO 20 GRAMS /NM3

PROTECTION FROM COLD END CORROSION

MINIMUM METAL TEMPERATURE REQUIRED FOR AVOIDING COLD END CORROSION IS 121 DEG. C FOR FUEL WITH SULPHUR CONTENT OF 4%.

THE METAL TEMPERATURE OF ALL TUBES IN EVAPORATOR (MAIN BOILER) AND ECONOMIZER IN PARTICULAR IS MAINTAINED ABOVE THIS LEVEL TO AVOID COLD END CORROSION.

IN ECONOMIZER, TEMPERATURE CORRECTION SYSTEM IS PROVIDED TO MAINTAIN METAL TEMPERATURE SINCE FEED WATER TEMPERATURE IS LOWER THAN 121 DEG.C
