[0002] Coke diced is usually used as a defective metallurgical coke. It has the characteristics of poor strength, poor permeability, and poor high-temperature performance. Therefore, coke diced is a very important energy product. Usually, the production of coke diced is also very important. Coke powder is the screened material of coke and is also one of the raw materials for preparing coke diced. The preparation process is usually called coke powder re-matching. Under the current situation of tight domestic coal supply, coke powder re-matching can increase the value of coke end and save some coking coal through reprocessing and utilization.
