Jun 06, 2017 The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600 o F. This high temp causes the coke to burn and melt the iron.
Dec 08, 2020 Blast Furnace. The current blast furnace is a giant steel shell built like a cylinder and packed with heat-resistant bricks. For the coke steel making process, iron ore, coke, and limestone are pumped into the furnace from the top and eventually sink straight to the bottom, becoming hotter as they go down.In the upper half of the furnace, coke-burning gas releases
