Iron ore sinter making - restaurantlastresafr.The sintering process of iron ore fines | ispatgu the process of sintering is basically a pre-treatment process step during iron making to produce charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes collected dusts, sludge and mill scale etc price.
Sinter is the primary feed material for making iron in a blast furnace, and we have previously written about sintering and how it is a step between mining ore and steelmaking.The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process.
18 what is sinter sintering is the process of agglomeration of iron ore fines into a porous mass by incipient fusion heat generated within the mass itself.19 types of sinter depending upon weather bases have been incorporated in the sinter mix, sinters are divided into three broad classes - i non fluxed or acid sinters - those.
In a real sintering process, iron ore grains, several millime-ters in size, are covered with fines of fe 2 o 3, caco 3, gangues, and coke.The chemistry in the portions where adhesive layers form changes greatly depending on how these fines are mixed and distr-ib uted.The size range of the above prepared mixture was selected.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel coke.The purpose of the sintering process is manufacturing a product with the suitable characteristics thermal, mechanical, physical and chemical to be fed to the blast furnace.
