Abstract The hot strength of coke, i.e., coke strength after the reaction and cold strength of coke, i.e., M40 are foremost aspects for assessing the quality of coke for the smooth operation of the bigger blast furnaces. The hot strength of coke measured in terms of coke CSR is a time-consuming process and lengthy. The repeatability of the …

Convexity is strongly influenced by the method used to crush the coke particles, with a relatively wide range of convexity values resulting from the different crushing methods. While there was some variation in convexity with particle size, the different crushing methods had a much greater effect on convexity.
