制订金属板冷轧工艺规程时,必须计算轧辊所受的压力,因而必须计算轧制时的平均单位压力及金属板的压缩量。但是计算平均单位压力的理论公式,一般都很复杂,许多参数不易确定,演算费时。在车间实际冷轧各种金属板时,常凭经验估计压缩量,难以知道轧辊所受的压力。因而往往造成损坏轧机及轧辊的事故;或过 When formulating the cold rolling process of sheet metal, the pressure on the roll must be calculated. Therefore, the average unit pressure during rolling and the amount of compression of the metal sheet must be calculated. However, the theoretical formulas for calculating the average unit pressure are generally complex and many parameters are not easy to determine, and the calculation takes time. When actually cold-rolling various metal plates in the shop, it is often difficult to know the pressure on the rolls due to the experience of estimating the amount of compression. Thus often causing damage to the rolling mill and roll the accident; or too
