Sintering: A Step Between Mining Iron Ore and Steelmaking
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. 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. Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron processing
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is ...

Modelling and analysis of the combustion behaviour of granulated fuel
1. Introduction. Sintering is very widely used around the world to prepare a lumpy ferrous feed for the ironmaking blast furnace. The sintering process involves the formation of a bed on a strand and the sequential combustion of solid fuel particles (typically coke) in the bed to form a narrow flame front, which travels downwards.
