前言随着现代化的连轧机在我国的增多,四十年代的轧辊管理方法已不适用。因为,四十年代的半连轧机和七十年代的武钢热轧机的轧辊管理,所处的生产条件发生了根本的变化。 (一)生产计划的改变四十年代生产计划的安排,从换辊方面讲:考虑轧制吨位的多少,则变动性很大。武钢热连轧机是以计算机预输入生产计划,计划以“单位”下达。因此,每一单位必须换辊。各单位的轧制吨位、规格品种有一固定要求,因此轧辊也针对单位发生变化。这样就要求轧辊管理严格,在一定的情况下,一单位的轧辊不能与另一单位混用。
Preface With the increase of modern continuous rolling mills in our country, the roll management methods of the 1940s are no longer applicable. Because of the roll management of semi-continuous rolling mills in the 1940s and hot rolling mills of the 1970s, fundamental changes have taken place in the production conditions. (A) changes in production plans Production arrangements in the forties arrangements, from the roll change: Considering the number of rolling tonnage, the great changes. WISCO hot rolling mill is a computer pre-input production plans, plans to “unit” issued. Therefore, each unit must roll change. All units of the rolling tonnage, specifications and varieties have a fixed requirement, so the roll also for the unit changes. This requires strict roll management, under certain circumstances, a unit of roll can not be mixed with another unit.
