what you should know about metallurgical coal

Aug 21, 2020 · Basic oxygen furnaces (BOF), which account for 70% of steel production worldwide, require iron ore, coke, and fluxes as feed material in steel production. After the blast furnace is fed with these materials, hot air is blown into the mixture. The air causes the coke to burn, raising temperatures to 1,700 degrees Celsius, which oxidizes impurities
