| Abstract: | In order to expand coking coal resources and reduce coal blending cost of coking enterprises, the feasibility of three gas coals (termed as QM1, QM2 and QM3) replacing 1/3 coking coal in industrial coal blending scheme was investigated through crucible coke and 40 kg coke oven tests, and the appropriate proportion of gas coal was optimized by vitrinite reflectance distribution diagram. The results showed that at the gas coal replacement ratio of 8%, the variation for cold strength of cokes were tiny, but its thermal strength was deteriorated, in which the CRI increased from 26.60% to 27.97%-29.79%, and the CSR decreased from 64.14% to 61.14%-62.82%. When the replacement ratio for QM3 was 5%, the coke quality was similar to that of original industrial blending scheme. While the replacement ratio for QM1 and QM2 was 5%, the CRI of cokes was about 2% higher and CSR was about 2% lower than those of original industrial coal blending scheme. In view of industrial coal blending scheme for producing primary metallurgical coke, it was feasible to replace the 1/3 coking coal with 5% QM3, which could reduce the cost of coal at least 15 yuan per ton of coke, and the appropriate proportion of QM1 and QM2 should be less than 5%. |
