用途及功能 Applications and function
1、 适用于普碳钢、不锈钢、特种钢等带材轧制。
2、 分工作辊和支承辊传动方式:普通电动压下和AGC 液压压下两种控制方式。
3、 可配置工作辊液压弯辊装置,能迅速调整轧辊的凸 度,改变间接触压力分布,达到控制板形的目的。
4、 整机结构简单,维修操作方便、投资少。
5、 AGC四辊轧机控制精度高,尤其适合于高精度冷轧 带的生产。
1、Suitable for mild steel,stainless steel and special steel.
2、Transmission method:working rollers transmission and supporting rollers transmission.control methods:common electric pressing down and hydraulic pressing down through AGC system.
3、Equipped with hydraulic bending installations of working rollers which can fast adjust the gibbous degree of rollers to change the distribution of touching pressure between rollers in order to control the plate form.
4、With simple construction, easy maintenance ,and less investment.
5、It is equipped with AGC system to get high precision,which is especially suitable for rolling high precision requirements of cold rolled strips.
