摘要
叙述了捣固炼焦配煤与焦炭质量的关系及捣固强度与配煤的关联性。指出:焦炭质量的基础是配煤质量,不会因煤准备和炼焦工艺等有根本性的改变;捣固炼焦可多用低变质程度、高挥发分气煤类的炼焦煤生产出一定质量的焦炭;捣固炼焦配煤适当增加黏结性配煤比例可提高焦炭质量,但用接近顶装焦炉的配煤进行捣固炼焦将丧失其优势并引发问题。捣固焦炉的高宽比、加热方式和装煤除尘等问题需在生产实践中进一步探索。
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.
