Raw Material for Iron Making • 1. Iron Ore • Hematite (Fe203) – 58% of Total Reserve • Magnetite (Fe304) – 42% of Total Reserve • 2. Limestone or Dolomite • 3. Coke • 4. Coal • Input Materials for Blast Furnace • Iron Ore (10/40 mm) • Sinter and Pellet • Limestone (Flux) • Metallurgical Coke (Fuel) Pig Iron Molten Iron taped from the BF Fe 90-95% OUTPUT PROCESS Total metallic yield Fe for pig iron will typically be in the range of 90 – 95 % which is comparable to #1 prompt scrap • Input Materials for Direct-reduced iron (DRI) • Iron Ore (5/40 mm) • Pellet • Limestone or Dolomite (Flux) • Natural Gas or Non Coking Coal Sponge Iron Iron produced as a solid by reduction of Iron Oxide Fe 90-92% OUTPUT • Input Materials for Smelting Reduction (SR) • Iron Ore (-6/30 mm) • Pellet • Limestone or Dolomite (Flux) • Oxygen and Non Coking Coal OUTPUT Liquid Iron Which utilize Oxygen and Non Coking Coal Fe 97%
Agglomeration of Iron Ore Fines • Agglomeration of Iron Ore Fines basically involves two main methods • Sintering • Pelletising • Sintering is the agglomeration technique of Iron Ore Fines in the size rage of -10+0.15 mm to produce clusters by incipient fusion at high temperature. • Pelletisation is the other mode of agglomeration applicable for fines below 325 mesh size.
Agglomeration (Sintering & Pelletising) • Common methods of burden preparation related to the performance improvements of iron making (blast furnaces & direct reduction process) • Growth of steel industry with depleting resources of high grade ores have led to a very strong demand for both pelletising and sintering of iron ores.
Pellet Plant The process of Pelletisation helps converting Iron Ore Fines into “Uniform Size Iron Ore Pallets” that can be fed in the blast furnaces or in the DRI kiln (DRI). Pelletisation was invented to make use of ultra fine concentrate generated in the Iron ore beneficiation plants There are two main processes for producing iron ore pellets: (1).The Grate-Kiln System (2).The straight grate system
Pellet Plant-Grate-Kiln System Process adopts three equipment viz. grate, rotary kiln and annular cooler Green balls are first dried and preheated on the straight grate followed by hardening in a counter flow manner in rotary kiln and air cooling in an annular cooler
Pellet Plant-Straight Grate System In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones.
Sinter Plant Sinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace.
Indian Steel Industry – 12TH Plan 2012-2017 • Steel production of the country will go up by 90 MTPA in 2016-17 from 89 MTPA likely in FY11-12. • It is estimated with feasibility factor that 21 MTPA shall be installed • 50 MTPA Ore Beneficiation • 50 MTPA Pellet Plant • As per SAIL Vision 2020 (60 MTPA) Source: Report of the working group on steel industry 12TH plan
Need for PelletisationContd. ADVANTAGES OF PELLETS: • Good Reducibility: • Because of their high porosity that is (25-30%), pellets are usually reduced • considerably faster than hard burden sinter or hard natural ores/lump ores. • • Good Bed Permeability: • Their spherical shapes and containing open pores, gives them good bed permeability. Low angle of repose however is a drawback for pellet and creates uneven binder distribution. • • High uniform Porosity (25-30%): • Because of high uniform porosity of pellets, faster reduction and high metallization takes place. • • Less heat consumption than sintering. • Approx. 35-40% less heat required than sintering. • • Uniform chemical composition & very low LOI: • The chemical analysis is to a degree controllable in the concentration processing • within limits dictated by economics. In reality no LOI makes them cost effective. • • Easy handling and transportation. • Unlike Sinter, pellets have high strength and can be transported to long distances without fine generation. It has also good resistance to disintegration.
