冷轧带材的平直度是一个很重要的质量标志,它对下步轧制时的故障次数和轧制速度有决定性的影响。基于这种原因,我们特研制一种平直度测量及调节系统,即轧制时通过控制辊缝来调节轧制铝材的平直度。藉此,便能同时提高轧制的产量和质量。在四重轧机上可控制辊缝的普遍做法是将轧辊倾斜、工作辊弯曲以及采取多区段冷却法。 The flatness of cold rolled strip is a very important quality mark, which has a decisive influence on the number of failures and the rolling speed during the next rolling. For this reason, we have developed a flatness measurement and adjustment system, that is rolled by controlling the roll gap to adjust the straightness of rolled aluminum. As a result, the yield and quality of the rolling can be improved at the same time. The common practice of controlling the roll gap on a four-high mill is to tilt the rolls, flex the work rolls and adopt a multi-zone cooling method.
