How does the blast furnace work?
How does the blast furnace work? The Blast Furnace is a large steel structure about 30 metres high. It is lined with refractory firebricks that can withstand temperatures approaching 2000 o C. The furnace gets its name from the method that is used to heat it. Preheated air at about 1000 o C is blasted into the furnace through nozzles near its base.. The largest Blast Furnaces in the UK ...
Use of Blast Furnace Slag Aggregate in Concrete IJSER
(limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product. When the blast furnace is tapped to release the molten iron, it flows from the furnace with molten slag floating on its upper surface.
