With the aid of advanced analysis and determination methods,the coal quality and coking characteristics of coking coal from the USA and Russia were comprehensively analyzed and evaluated.The two type of coals belong to high metamorphic coking coal with low ash,low sulfur,poor caking property,moderate coking property and poor coke strength after reaction(CSR).Moreover,the coals from Russia are better lean coking coals and have more advantages in extremely low sulfur as well as price.Based on actual operation,the two kinds of coal can be used as lean coking coal in coal blending,which is beneficial to adjust the particle size of the coke.Measures are taken to optimize the blending amount and ensure the caking property of the blended coal.As a result,coke with better mechanical strength and CRI/CSR can be obtained and the cost of coal blending can be reduced.
