【摘要】 在工艺润滑和高速钢工作辊的影响下,CSP生产线的轧制力不能简单地用热轧公式计算。将Sims公式和Hill公式进行加权求和得到应力状态系数,结合CSP生产线生产数据,以预测与实测轧制力差值最小为目标定义目标函数,采用变量轮换的优化方法,找到使得目标函数最小时的摩擦系数。以此摩擦系数为因变量,建立摩擦系数的模型和轧制力数学模型。结果表明:Hill公式更适合CSP轧制力的计算,预测值与实测值的相对误差仅在3%左右,模型精度较高。更多还原

【Abstract】 Under the influence of technological lubrication and working roll of high-speed steel,the rolling force of CSP line could not be easily calculated by the formula of hot rolling. The coefficient stress condition was based on the weighted sum of Sims formula and Hill formula. Combined with the production data of CSP line,the objective function was defined by the minimum deviation between calculated values and actual data. With the optimizing method of cyclic variable method,the corresponding friction coefficient could be obtained. Regarding it as dependent variable, the mathematical model of friction coefficient and rolling force was developed. The results showed that Hill formula was more suitable for calculation on CSP line. The relative deviation between calculated values and actual data was about 3%,so the new model was more accurate.更多还原
