Application method of coking coal for producing metallurgical coke

Abstract

The invention relates to a coking coal application method for producing metallurgical coke. The method comprises the following steps: (1) establishing a single coal classification model for coking; (2) establishing a blended coal preparation model; (3) formulating a theoretical coal blending scheme and verifying the theoretical coal blending scheme; and (4) carrying out coal blending coking according to the coal blending scheme verified to be qualified. According to the method, the coking coal application system combining the single-coal evaluation classification model for coking, the blended coal scheme making model and the coke oven temperature index control model is constructed, so that the accuracy and effectiveness of coking coal evaluation are improved, the coal blending structure is better guided and optimized, the consumption of high-quality coking coal is saved, and the coal blending cost is controlled and optimized; meanwhile, control over a coke oven heating system is improved, gas consumption is reduced, coke quality is stably improved, energy conservation and emission reduction are facilitated, and high-quality application of coking coal in metallurgical coke production is achieved.
