Problems solved by technology

At present, the use of coking coal in my country mainly depends on the vitrinite reflectance and its distribution of the traditional coal quality indicators and coal rock indicators, as well as the activity-inert ratio. These two indicators and the combination of these two indicators have certain defects. The rational use of coking coal cannot be achieved, and the goal of stably improving coke quality and reducing coal blending costs cannot be achieved

Abstract

The invention relates to a method for coking and mixing coal by the participation of coking coal. The method comprises the following steps: (1) detecting the coking coal: a detection result at least comprises maximal fluidity; (2) sorting the coking coal according to the maximal fluidity detected in the step (1); and (3) mixing the coal. According to related indexes of the coking coal, the method reasonably divides the coking coal so as to reasonably utilize coking coal resource, and can reduce the cost for mixing the coal under the condition of not influencing the quality of the coking coal.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a method for coking coal blending, in particular to a method for coking coal participating in coking coal blending. Background technique [0002] my country is rich in coal resources, but coking coal resources are in short supply, and the limited coking coal resources are not evenly distributed. Among the proven coal reserves, coking coal reserves account for only 26% of the total coal reserves, coking coal accounts for only 17.57% of coking coal reserves, and fat coal accounts for 10%. In coal blending and coking, coke fat coal should generally account for 50% to 60%, and there is a serious contradiction between coking coal resources and demand for coking coal blending. Therefore, how to make good use of limited coking coal resources has become a problem that coking workers must face. At present, the use of coking coal in my country mainly depends on the vitrinite reflectance a...
