Improvement of hydraulic circuit of roll balance system;
轧辊平衡液压控制回路的改进
In this article,phenomenon causing slippage of roll face between working roll and backing roll for four high mill is analyzed and it is pointed out that increasing equilibrant of working roll can not prevent slippage phenomena foom occurring The criterion is delivered,when the slippage phenomenon appeared.
分析了轧辊平衡力对四辊轧机工作辊与支承辊间打滑现象的作用关系。
By analysis of the hydraulic circuit of a roller balance system,the main problem of the circuit when changing rollers is pointed out.
提出了一种基于液压差动回路的控制方案,并对该方案的控制效果从原理方面进行了分析,指出该回路在对轧辊平衡装置进行控制方面较原来的控制回路具有明显的优越性。
