国产修磨机台车精准控制研究

Precision Control of Domestic Grinding Trolley

一炼钢厂国产修磨机,承载着公司钢坯的修磨任务。修磨机主要由磨头、台车和上下料台架构成。台车作为一个过渡和承载单元,它的精准运动直接影响到钢坯的修磨效果。国产修磨台车是由液压滚筒来驱动的。台车速度控制依据不同的操作模式和不同的控制要求来设计,根据修磨的功率和修磨深度,把给定速度转换为卷筒换向阀的输出,来精确控制台车往返。

The domestic grinding machine of a steel making plant carried the grinding task of the company’s billets. The grinding machine was mainly composed of a grinding head a trolley and a loading and unloading platform. The trolley as a transition and load-bearing unit,whose precise movement directly affected the grinding effect of the billet. The domestic grinding trolley was driven by a hydraulic roller. The speed control of the trolley was designed according to different operating modes and different control requirements. According to the grinding power and grinding depth,the speed output was converted to the reel proportional reversing valve given to accurately control the vehicle back and forth.
