Example Embodiment
[0022] The present invention will be described in detail below with reference to specific embodiments, but the present invention is not limited to the following embodiments.
[0023] Use 6m coke oven for coking, 20h coking time, dry quenching. There are six types of coking coal used, namely gas coal, 1 / 3 coking coal, gas fat coal, fat coal, coking coal and lean coal. Gas coal comes from Shandong Zaozhuang Mining Bureau and Xinwen Mining Bureau, 1 / 3 of coking coal comes from Henan Pingmei Group, gas fat coal comes from Shandong Xinwen Mining Bureau, fat coal Shandong Zaozhuang Mining Bureau, coking coal comes from Shanxi Coking Coal Group, Lean coal comes from Anhui Huaibei Mining Bureau.
[0024] Firstly, the overall quality of the coking coal is analyzed; secondly, according to the weight ratio, select 1 / 3 coking coal or 24% gas coal, 12%-18% gas fat coal, 0%-12% fat coal, 42% coking coal and lean coal. The coal content is 10%, and 4 coal blending schemes are obtained as shown i...
