METHOD FOR ESTIMATING COKE STRENGTH AFTER REACTION

摘要

A method of estimating the hot strength of coke with improved accuracy using factors related to the amount of coal components and hot properties of coal is provided. As a method for estimating the hot strength of coke used for manufacturing molten iron, the hot strength (CSR) of coke satisfies the following equation.^{CSR = -4.2O - 88.2Rm 2 + 185Rm} + 1.85Ash 2 - 31Ash + 109.7 Here, O is the amount of oxygen contained in the coal used as coke (vol%), Rm is the reflectance of coal, and Ash is the amount of ash contained in the coal (wt%).
