Abstract:

Because of ordinary UCM temper mill could not equip cooling means and had no choice to control asymmetric complex higher-order wave shape, a new AS-UCM temper mill was made up, which equipt work roll asymmetric bending, middle roll asymmetric bending, middle roll upward and downward asymmetric movement. This paper quantitatively analyzed the ability of AS-UCM temper mill by controlling loading roll gap shape, then established a shape control model fit for AS-UCM temper mill. By comparing the ability of AS-UCM temper mill and ordinary UCM temper mill by controlling asymmetric complex higher-order  wave shape under same condition, it concludes that the ability of AS-UCM temper mill by controlling asymmetric complex higher-order wave shape is more useful than the ordinary UCM temper mill. The model provides helpful references for controlling temper mill complex higher-order wave shape.

摘要：

针对普通UCM平整机组因不能配置分段冷却手段而无法对板形的非对称复杂高次浪形进行精细控制的问题,研发了一套配置工作辊非对称弯辊、中间辊非对称弯辊、中间辊上下非对称窜辊的AS-UCM新机型，定量分析了AS-UCM机型对负载辊缝形状的控制能力，建立了一套适合于AS-UCM机型平整机组的板形控制模型，并在相同初始条件下将AS-UCM机型与普通UCM机型平整机组对非对称复杂高次浪形的控制效果进行了对比，得出了采用AS-UCM机型的平整机组比普通UCM平整机组对非对称高次复杂浪形的控制能力大大增强的结论，从而为平整机组高次复杂浪形的治理提供了参考。
