Blast Furnace Charge (Raw Materials for Steel-making) - .

1. QUALITY OF CHARGE MATERIAL: A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (40-60 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the flue-gas passages and prevent a uniform descent of melting materials in the furnace. 2.
