2800mm中板轧机幂函数曲线辊型的研究

Study on Roll Contour with Power Function Curve in 2800mm Plate Rolling Mill

根据中厚板轧机轧制力和轧件宽度变化范围大的特点,在研制2800mm轧机辊型中,通过引进压力加权系数和宽度加权系数,使设计出的幂函数曲线辊型能自适应于生产中各品种规格的变化,特别是实现了工作辊辊型在支撑辊的整个服役期内可保持不变的目的,从而大大简化了工作辊的管理和储备量。生产实践表明,该辊型使用效果显著。

According to characteristic of plate rolling mill which includes wide rolling force range and wide work-piece width range, the article introduces force weighted coefficient and width weighted coefficient in roll contour research of 2800mm plate rolling mill. Power function curve roll contour designed by this method can self adapt to change of production specification. Especially, it achieves that work roll contour maintain invariable during the service period of backup roll, consequently simplify work roll manage and decrease its store number. Workshop practice confirmed that the method achieve good results.
