轧钢工作者往往用强化轧制过程的办法来缩短生产周期,从而提高轧机的机时能力,特别是在当前的形势下,大胆而科学的修改孔型减少轧制道次,已经成为刻不容缓的工作了。然而在粗轧、毛轧系统中强化压下量往往被啃入条件所限制,在轧机较小的工厂中这一问题就更为突出。我厂为改善啃入条件曾做过一些试验工作,限于工作水平只能浮浅介绍,祁望各厂协助研究指正。改善啃入条件的重要性在一般情况下,分配延伸系数或压下量多是顺从轧制道次而递减理想情况如图1所示。但实际情况往往因啃入角的限制前几道不能采用较大的延伸系数,
Rolling workers often use the process of strengthening the rolling process to shorten the production cycle, thereby improving the rolling mill capacity, especially in the current situation, the bold and scientific modification hole reduction rolling pass, has become an urgent task It’s However, in the roughing and rolling systems, the amount of strengthening and reduction is often limited by the conditions of bite entry, which is even more prominent in the smaller mill. I plant to improve the eating conditions have done some experimental work, limited to the level of work can only be described as shallow, Qi Wang plant to help correct the study. IMPORTANCE TO IMPROVE NICKING CONDITIONS In general, assigning an extension coefficient or reduction is mostly a matter of decreasing compliance with a rolling pass, as shown in Figure 1. However, the actual situation is often due to bite into the corner of the first few Road can not use a larger extension factor,
