Abstract:In order to actively cope with the impact of changing factors such as tight supply of coking coal resources, quality decline and price fluctuation, etc., coking coal resources and coal blending structure were optimized, the market was going deep to explore new coking coal resources with the technical support of small coke oven test and coal petrography analysis. The quality performance of new resources and the blending proportion of each coking coal was studied, and a variety of coal blending optimization schemes for adding Wangjialing lean coking coal were carried out. On the basis of maintaining the coke strength, the lean coal ratio was increased to 14%. By calculating the sulfur content and caking index of blended coal, the coking coal resources are expanded, and by using ordinary coking coal to replace some high price and low sulfur Liulin coking coal, the company′s blending cost is reduced.
