Abstract:

This paper introduces the application of improving the coke M40 acceptability rate in Shasteel 7.63 m coke oven.Through establishing the contribution rate of individual kind of coal to coke M40,optimizing coal blending by using vitrinite reflectance and Gieseler fluidity,plus cokemaking process like CDQ,thus the M40 compliance rate can be steadily improved.The high-quality metallurgical coke can be used for 5,800  m3 blast furnace,which ensures the smooth operation of the blast furnace.

Key words: 7.63 m coke oven, 5,800 m3 blast furnace, M40 acceptability rate, Coke quality
