Abstract: The main influencing factors of metallurgical coke rate were determined as blended coal ash,coke M10,coking time and blended coal sulfur,and the regression equation was obtained by regression analysis so that quantitative algorithm for metallurgical coke rate can be realized.However,due to unstable factors in cokemaking operation and a certain deviation in statistics,it results in not fully reliable regression equation.Coke plant can use the idea of this paper for reference to quantify the algorithm before the regression analysis according to its own situation.
