Coke is coal in isolation under the conditions of high temperature air dry distillation get of the product. Main purpose: it is widely used in iron and non-ferrous metal smelting, casting, chemical industry, calcium carbide and ferroalloy, etc.
Metallurgical coke is produced by carbonization of coals or coal blends at temperatures up to 1400 K to produce a macroporous carbon material of high strength and relatively large lump size.
Metallurgical cokes must have a high strength to support heavy loads in the blast furnace without disintegration. Metallurgical coke is also used as filler coke for polygranular carbon products.
