조습시 코크스 제조용 원료탄의 배합방법
摘要:
PURPOSE: A combination method of crude coal for preparing cokes with controlled moisture content is provided for restricting ash, volatile matter(VM), log maximum fluidity(LMF), total dilatation(TD), mean reflectance(RM), composition balance index(CBI), strength index(SI) or total sulfur(TS). CONSTITUTION: The method for combining crude coal comprises to produce metallurgical cokes by introducing coal after controlling moisture content of the coal to 5.5-6.5%. The method is to accomplish less than 8.5% ash, 24.0-28.0% volatile matter, 2.32-2.58 LMF(log ddpm), 83-107% TD, 0.9-1.02 RM, 1.2-1.8 CBI, 3.5-4.0 SI and less than 0.7% by combining crude coal. The obtained coal combination can provide 200mm H2O or less of gas pressure when it is used in the production of cokes and can accomplish more than 86.0 of drum index(DI) and 65.0 or above of coke strength after reaction(CSR) for the produced cokes.
