The Roles of Coal and Coke in SteelmakingHow it works: The Blast Furnace - Stoke-on-Trent

Jul 16, &#; Another well-known process of steel making is completed with an electric arc furnace Unlike a blast furnace, an electric arc furnace uses no iron in steel making Coke and coal are not required during this process, as it uses electricity instead Coke is often produced away from the steel mills, and is often delivered via railwayOnce a blast furnace is started it will continuously run for four to ten years with only short stops to perform planned maintenance The Process Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter The raw ore is removed from the earth and sized into pieces that range from 05 to 15 inch.
