The main component of coke The main component of coke is carbon, which is a porous structure with cracks and irregularities. The number of cracks directly affects the strength and compressive strength of coke, and its index is generally measured by crack degree (referring to the length of cracks in unit volume coke).

Porosity is the main index to measure the pore structure of coke, which affects the reactivity and strength of coke. Different uses of coke require different porosity indexes, such as metallurgical coke 40-45%, casting coke 35-40% and export coke 30%.

The cracking degree and porosity of coke are directly related to coking coal. For example, coke made of gas coal has many cracks, high porosity and low strength. However, coke made from coking coal has less cracks, low porosity and high strength. Coke strength is usually expressed by two indicators: crushing strength and wear resistance. Hope to adopt
