Description / Application. Metallurgical coke, is a carbon material manufactured by the destructive distillation of various blends of bituminous coal. Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatile constituents are driven off by baking in an oven without oxygen at temperatures as high as 1,000 C so that the fixed carbon and ...

Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. 3.19.1.1.2 Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.

The coal is heated to 1.250 C in the coke ovens. Since these ovens are oxygen-free, the coal does not actually burn. This process is referred to as ‘dry distillation’. It takes about 18 hours to convert 35 tonnes of coal into 25 tonnes of metallurgical coke. The coke cake is unloaded from the oven by a pusher machine, which is equipped ...

Briquetting increases strength of coke produced and to make non - coking or poorly coking coals to be used as metallurgical coke. Blending prevents damage to oven when high pressure develops. (b) Coke oven: Oven has usually 0.3 to 0.6m width. Here coal is kept for 17 hrs, heat is supplied completely from the flues on the sides.
