随着我国冶金工业的蓬勃发展,冷轧薄板的生产量急剧增加,轧机的种类也日益增多,对冷轧辊数量和质量的要求越来越高。目前,冷轧板(卷)生产的特点是采用连续强化冷轧工艺(提高轧制速度,增加压下量和轧制力),这是普通钢制轧辊难以承受的。一般,轧辊损耗占生产薄板固有损耗量总支出项目的25%。不言而喻,必须找出降低损耗的方法和多快好省生产冷轧辊的途径。
With the vigorous development of China’s metallurgical industry, the production of cold-rolled sheet increased sharply, the type of rolling mill is also increasing, and the requirements on the quantity and quality of cold-rolled roll are getting higher and higher. Currently, the production of cold-rolled sheet (coil) is characterized by the continuous strengthening of the cold-rolling process (to increase the rolling speed, increase the reduction and rolling force), which is unbearable ordinary steel roll. In general, roll losses account for 25% of the total expenditures for the production of sheets. It goes without saying that it is necessary to find a way to reduce the wear and tear and how to produce a cold roll at a faster rate.
