超薄快速铸轧机铸轧辊温度场和热凸度仿真及实验

Emulation and test research of temperature field and thermal crown for super-thin high-speed mills roll

轧辊热凸度是影响板形的一个重要因素 ,其计算精度直接影响到成品的板凸度和板形精度。采用轴对称差分法计算了超薄快速铸轧机铸轧辊温度场和热凸度 ,计算结果与现场测试结果相吻合 。

The thermal crown of high speed cast rolls is a very important factor influencing the thickness transverse distribution of hot strip mills, and the final crown and shape quality of strip. The cast roll's temperature field and hot crown for super thin high speed mill roll were calculated by implicit differentia method. The results show good agreement with test results. [
