Abstract:

The relation between the coal blending for the cokemaking with stamping coke oven and coke quality and relevancy between stamping strength and coal blending are described. It is pointed that the base of coke quality is the quality of coal blending, no fundamental change occurs because of coal preparation, cokemaking process and so on; the cokemaking with stamping coke oven can use more gas coking coal that has low deterioration degree and high volatile matter, to produce a certain quality coke, for the coal blending for cokemaking with stamping coke oven, the proportion of caking coal can be increased in coal blending so as to improve coke quality, but the cokemaking with stamping coke oven with about same coal blending for top charge coke oven will lose its superiority and cause problem. The issues of height and width ratio, heating mode and coal charging de-dusting etc. need to be further explored in the production practice.
