Abstract:

The difference of coke cake shrinkage of the stamp-charging cokemaking and top charging cokemaking as well as the influence factors were analyzed. The problems of low volatile coal blend in stamp-charging cokemaking design and production were studied, and the following measures were put forward:  heating level was properly reduced； the coking time was rationally set；the charging car which can adjust the width of coal cake was designed；according to Vdaf value and X value of coal blends, the coal cake width and height were adjusted, the production was guided with XD value so as to ensure that there was enough gap between coal cake and oven wall and suitable space temperature.
