基于影响函数法建立六辊冷轧机辊系弹性变形计算模型，从理论上深入分析了主要因素如单位宽度轧制力、中间辊横移位置等对最佳弯辊力的影响，从而建立了合理的弯辊力设定模型。根据中间辊弯辊力与工作辊弯辊力之间存在的关系，建立了更为简化的中间辊弯辊力设定模型，降低了模型现场调试和维护的难度。现场应用效果表明，弯辊力设定值与实测值之间偏差在±20%以外的仅占总数的5.25%，这说明模型具有较高的设定精度。
An elastic deformation model for the roll stack of six-high cold rolling mill was built based on the influence function method. The factors affecting the optimum bending force such as specific rolling force and intermediate roll shift-ing were analyzed theoretically, and a more reasonable bending force preset model was established. Meanwhile, a simpli-fied preset model of intermediate roll bending force was built according to the relationship between the intermediate roll bending force and the work roll bending force, which can reduce the difficulty of commissioning and maintenance. On-site application results show that the preset model has high precision and only 5.25%of the deviation between the preset and the measured bending forces was out of the range of ±20%.
