Title: Production of reduced iron pellet
Inventor: IBARAKI TETSUJI
IPC: C22B1/216
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To enable direct using of reduced iron pellet in a blast furnace by controlling reaction temp. in a furnace to regulate residual carbon ratio after completing the reaction to a specific value or lower and the collapsing strength to high. SOLUTION: Green pellet consisting essentially of iron oxide mixed with coal, coke and the other carbon source as reducing agent is heated in a rotary hearth type burning reduction furnace to produce metallic iron by the reducing reaction. In this operation, the reaction temp. is regulated to <=1,400 deg.C and the residual carbon ratio in the reduced iron pellet after reducing reaction is limited to <=4%. Thus, the high strength reduced iron pellet having >=50 kgf/cm2 collapsing strength can be produced by satisfying these conditions. In the case of being the reaction temp. of >1,400 deg.C in the reducing operation, the lowering of the strength is developed and this reduced iron pellet has the strength of only <=50 kgf/cm2. In the high strength reduced iron pellet, the metallic iron is distributed in the whole pellet and the strength is developed with the network of the metallic iron and this reduced iron pellet having so high as >=200 kgf/cm2 can be obtd.
