卷取机AJC踏步控制

Coiler AJC Step Control

全液压地下卷取机助卷辊卷取方式一般分为3种,即恒压力方式(压力控制)、连续打开(位置控制)和踏步方式(压力和位置控制)。其中,踏步方式对控制的要求最高。踏步功能作为热轧卷取机最为重要的功能之一,对减少带钢头部压痕、减少带钢头部卷取时对设备的冲击、提高成品钢卷的卷取质量起着非常重要的作用。本文结合软件编程设计思路和工程实践,对影响踏步控制的关键因素——带钢头部跟踪、跳跃量和起跳时机、助卷辊辊缝计算等进行了分析,此功能已在宁波1 780 mm热轧改造项目中得到了应用,效果良好。

Full hydraulic underground coiler roll winding approach is generally divided into three kinds, namely, the constant pressure mode （ pressure control ）, continuous open （ position control ） and the stepping mode （ pressure and position control ）. Among them, the stepping mode for maximum control requirements. One of the stepping function as coiling machine most important function of reducing the strip head indentation, reducing the impact of strip head coiling equipment, improve the quality of the finished coil winding plays a very important effect. In this paper, software programming design ideas and engineering practice, the key factors affecting the Step Control - the strip head tracking, jumping off the amount and timing of wrapper roll joints were analyzed to calculate, this feature has been in Ningbo, 1 780 mm Hot-rolled reconstruction project has been applied to good effect.
