武钢冷轧厂以五机架冷连轧机节能为目标,以单位时间体积流量最大,马达功率总消耗最小指标函数,研制了冷连轧机能耗最小轧制规程预设定的数学模型,并采用动态规化法进行在线最优化计算。该模型在线生产使用20个月,共轧制各种规格带钢约35万吨左右,运行正常,控制可靠,达到原西德模型控制生产水平。并可降低电耗3～5％,经济效益显著。
Taking the energy saving of five-stand tandem cold mill as the goal, WISCO cold rolling mill developed the mathematical model pre-set for minimum rolling schedule of cold tandem mill based on the maximum volume flow per unit time and the minimum index of motor power consumption. Dynamic normalization method for online optimization. The model was used online for 20 months and rolled a total of about 350,000 tons of strip with various specifications. The model was operated normally with reliable control and reached the level of production control of the former West German model. And can reduce power consumption 3 ~ 5%, significant economic benefits.
