CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

2012-8-16  In sintering, a shallow bed of fine particles is agglomerated by heat exchange and partial fusion of the quiescent mass. Heat is generated by combustion of a solid fuel ad mixed with the bed of fines being agglomerated. The combustion is initiated by igniting the fuel exposed at the surface of the bed after which a narrow, high temperature zone is caused to more through the bed by an induced draft applied at the bottom of bed. The bonding is effected by a combination of fusion, grain growth and slag liquidation. The generation of volatiles from the fuel and flux stone creates a frothy condition and the incoming air quenches and solidifies the rear edge of the advancing fusion zone. The product 'sinter' consists of a cellular mass of ore bonded in a slag matrix. The sinter mix, besides the ore fines, usually contains other materials like flue dust, return fines, limestone and/or dolomite etc., in order to control the properties of the product as well as to utilize industrial waste.
