A method for blast furnace melting comprises the block charging of increased by weight of coke portions and iron-ore materials through blast furnace throat, preliminary mixing of iron-ore materials with lump coal at the set mass ratio. The maximum possible part of coke replaced with coal in total masse of lump fuel is charged into blast furnace is installed subject to hot resistance of coke from the ratio: B=0.28·(CSR)+0.0014·(CSR),where B – part of coke which is replaced coal in total masse of charged lump fuel, %, CSR – index of hot resistance of coke, %. |
