摘　　要：基于焦炉内煤在加热和膨胀过程中产生的过大压力是焦炭和钢铁生产者的主要安全问题之一,如果结焦压力过高会给焦炉生产带来许多比较麻烦的问题,如果太轻就会使推焦变得困难,如果太重就会使焦炉壁因为巨大压力而被严重损坏,使其使用寿命并降低。如果适当的结焦压力反而又有利于煤的粘结[1]。解决膨胀压力这一问题是很有必要的。这对如何合理利用这些煤炭资源对炼焦行业的生产和发展具有极其重要的意义。Excessive pressure in the process of heating and expansion of coal in coke oven is one of the main safety problems for coke and steel producers.High coking pressure will bring many problems to coke oven production.At light,it is difficult to push coke,and atheavy,the huge pressure on the wall of coke oven will seriously damage the oven and reduce its service life.Appropriate cokingpressure is beneficial to coal bonding.It is necessary to solve the problem of expansion pressure.How to rationally utilize these coal resources is of great significance to the production and development of coking industry。
