在初轧或开坯生产中,对孔型如何能在理想的咬入条件下获得较大的压下量,是轧钢生产者十分关注的问题,它直接影响到企业的效益,生产的稳定和产品的质量。 我厂对初轧机打滑影响正常生产这一问题,一直采用如电弧堆焊、炭弧气泡铲削,钳工用凿凿削、钻床打浅眼等简单的方法,这不但不能根本解决,且会使孔型的表层发生变化,给轧辊重车带来一定困难,另外还 In the initial rolling or billet production, the hole how to obtain the ideal under the conditions of biting under a large amount of rolling, rolling producers are very concerned about the issue, which directly affects the efficiency of enterprises, production and stability Quality of products. I plant on the initial rolling mill slip affecting the normal production of this issue, has been used, such as arc welding, carbon arc bubble shovel cutting, fitter with chiseling cut, drill drilling shallow and simple method, which not only can not be fundamentally resolved, and will make the hole The surface of the type changes, to the roller heavy truck to bring some difficulties, the other also
