This paper shows a successful case that low-sulfur fat coal from Russia instead of domestic high-sulfur fat coal,blended with high-sulfur prime coking coal achieved satisfactory result of coal blending,with stable coke quality and lower cost in coal blending.Through 40 kg pilot oven test,ash composition analysis and microscopic analysis etc.,the properties and application of the low-sulfur fat coal from Russia were analyzed.When the volatile ratio in the fat coal from Russia exceeds 33%,and the blending ratio of that is less than 5%,there would be no obvious influence on mechanical strength and CRI/CSR;when the blending ratio of the fat coal exceeds 7%,CSR deteriorated significantly.
