Blast Furnace Equipments
Blast furnace is a counter-concurrent gas solid
smelting furnace where agglomerated raw materials (Coke + Fe ore +
Limestone) is converted to hot metal by addition of reducing agents.
Approximate weight and height of a blast furnace is 10,000 tons and 35
A blast furnace is made of thick steel and has inner refractory linings
(shaft, belly, bosh charmotte brick + silicon carbide bricks and
hearth carbon bricks).
The final products from a blast furnace :
- hot metal, slag and hot gas.
- Hot metal is further treated and converted to the necessary products.
- Slag is the waste product used in various other industries like
- Hot gas is reused to preheat the hot blast of air used in blast
furnace itself for its operational purposes.
A blast furnace has several primary equipments, followed by several
