Iron smelting involves two main processes in the blast furnace 1 the reduction of iron from it compounds and 2 its separation from its physical mixture with gangue materials In furnace the charge is constantly moving slowing downward against the force flow of the very hot gases which bring about the evaporation of moisture from the.
A blast furnace is a gigantic steel stack lined with refractory brick where the concentrated iron ore coke and limestone are dumped from the top and a blast of hot air is blown into the bottom All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
