冷轧带钢的板形控制在国内外迄今仍是一项困难而又重要的课题,目前正处于由人工目测控制向自动控制过渡的阶段,但自动控制在国内仍处于空白状态,人工控制的水平也不高,这是我们在冷轧技术领域内同世界水平的重要差距之一。所以,研究探索冷轧带钢板形控制理论,用以指导板形质量工作,提高轧制工艺水平,进而提高生产效率,降低原材料消耗,具有十分重要的意义。一、板形控制基本知识 1.板形评定方法测量冷轧带钢板形平直度的理想方法是将带钢夹在两块乎直板之间,若其接触面为100%,则产品十分乎直,即板形最好。但这种测量方法难于在实践中实施,所以通常离线检查板形质量的方法是将带钢置于平板
The cold plate strip shape control is still a difficult and important subject at home and abroad so far, and it is in the stage of transition from manual visual control to automatic control. However, the automatic control is still in a blank state in China. The manual control The level is not high, which is one of the important gaps we have in the world of cold-rolled technology. Therefore, it is of great significance to study the strip shape control theory of cold rolled strip to guide the work of strip shape quality, improve the rolling process level, further improve the production efficiency and reduce the consumption of raw materials. First, the basic knowledge of the shape control 1. Shape evaluation method The ideal method of measuring the flatness of cold-rolled strip shape is to sandwich the strip between two pieces of straight board, if the contact surface is 100%, the product is very Straight, that is the best shape. However, this measurement method is difficult to implement in practice, so usually the method of checking the quality of the plate off the strip is placed on the plate
