5.横向厚度(板型)的自动控制保证冷轧带钢横向厚度均匀,并使其厚度偏差在工艺允许的公差范围之内,也就是通常所说的保证板型好,是衡量冷轧带钢质量的一个关键指标。因此,对冷轧带钢的板型进行检测和自动控制是非常必要的。 (1)影响板型的因素所谓冷轧带钢板型不好,是指带钢横向厚度不均,超过了工艺允许的范围。国外一般以波状系数δ/1％作为衡量板型好坏的指标,目前冷轧板最高指标要求δ/1％
5. Horizontal thickness (plate type) automatic control to ensure that the horizontal thickness of cold-rolled strip uniform, and to the thickness of the deviation within the allowable tolerance within the process, which is commonly referred to as plate to ensure good, is a measure of cold-rolled strip A key indicator of steel quality. Therefore, the cold-rolled strip plate for testing and automatic control is very necessary. (1) the factors that affect the plate type The so-called cold-rolled strip type is not good, refers to the strip horizontal thickness uneven, exceeding the allowable range of the process. Foreign generally corrugated coefficient δ / 1% as a measure of the type of good or bad indicators, the current highest level of cold-rolled sheet requires δ / 1%
