一、概况由于近代轧机要求轧制速度快,精度高(即厚差小)。电动压下已不能满足工艺和设备的要求。因为它本身不可克服的缺点是电动压下系统的惯性大,不可能有很高的频率响应(快速性,即每秒能启动、制动多少次),和设备传动效率低,大部分功率消耗在摩擦力矩、启动和制动的动力矩上。因此觅求:惯性小、重量轻(提高压下的速度和加速度)、效率高的控制装置成为提高带材轧制产量和质量的关键。于是从60年代以后,世界各国相继出现了各种液压轧机控制系统。武钢硅钢片厂是由日本引进的成套设备,其中森吉米尔轧机采用行星齿轮机械反
First, an overview Because of the requirements of modern rolling mill rolling speed, high precision (that is, small thickness difference). Electric pressure has been unable to meet the requirements of technology and equipment. Because of its inherent insurmountable disadvantage is that electric depressing system inertia is large, it is impossible to have a high frequency response (rapidity, that is, how many times per second can be started and stopped), and equipment transmission efficiency is low, most of the power consumption In the friction torque, starting and braking torque moment. Therefore, seeking: inertia is small, light weight (to reduce the pressure and acceleration), high efficiency control device has become the key to improving the output and quality of strip rolling. So from the 1960s onwards, various countries all over the world have appeared a variety of hydraulic rolling mill control system. WISCO silicon steel sheet plant is imported from Japan, complete sets of equipment, which Sendzimir mill planetary gear mechanical anti
