摘　　要：为研究轧辊凸度对带钢厚度的影响,分析并建立了轧辊弹性弯曲和弹性压扁影响函数矩阵,开发了基于影响函数法的TDC模块。在某1 450mm冷轧机上对该模块进行测试,其运行稳定、快速,满足精度要求。测试结果表明:当中间辊凸度增加时,轧件轧后厚度呈现增加的趋势。The influence function matrixes of elastic bending and flattening were established to research the influence of roll crown on strip thickness. The TDC module was developed on the base of influence function method. It was tested in a 1 450 mm cold rolling mill, and showed that the TDC module was steady and the control accuracy was satisfied. The test results showed that when intermediate roll crown increased, the tendency of strip thickness also increased.
