近年来,为了提高轧材质量,国外已研制出了多种新型轧机。从结构特点和工作原理看出:发展金属压力加工技术的总趋势是多种工艺和多种加工原理的联合。 下面分别介绍三种新型轧机: 一、轧辊成对交叉式轧机(PC轧机) 随着市场对强度高、平直度好的冷轧薄钢板的需求量日益增加,迫切要求开发板带材平直度的控制方法。近年来,在六辊轧机上采用调整中间辊的控制方式,大大提高了控制机能,并已得到实际应用。但是,上述六辊轧机轧辊数量较多,用四辊轧机改造相当复杂,特别是热轧机,设备改动量很大,而且适用范围有限。
In recent years, in order to improve the quality of rolled material, a variety of new rolling mills have been developed abroad. Seen from the structural characteristics and working principle, the general trend of developing metal pressure processing technology is the combination of various technologies and various processing principles. Three new types of rolling mill are described below: First, the roll paired cross-rolling mill (PC Mill) With the market for high strength, flatness of cold-rolled sheet steel demand is increasing, the urgent need to develop flat straight strip Degree of control methods. In recent years, the control method of adjusting the middle roller on a six-high rolling mill greatly improves the control function and has been practically used. However, the above-mentioned six-high mill roll number, with a four-high rolling mill transformation is quite complex, especially hot-rolling mill, a large amount of equipment changes, and the limited scope of application.
