宁钢2号板坯连铸机电动缸在线调宽的成功应用
|
摘要
描述了电动缸在线调宽在宁钢2号连铸机板坯连铸上改造过程中,通过理论计算和试验相结合,对在线调宽的软夹紧压力进行精确计算,并该结果在使用中得到验证;通过建立间隙策略模型很好的消除了机械间隙对窄边锥度的影响;软件上开发了模拟调宽功能,能够在非浇钢时,提前预演调宽过程,大大降低了调宽试验风险和试验成本。
This paper describes The electric actuator on-line width adjustment control system on No.2 slab caster in Ningbo Iron & Steel Co.,Ltd. Based on theoretical calculation and experiment,get the precise calculation of the soft clamping pressure of on-line width adjustment control system,and proved in actual operation. The influence of mechanical clearance on narrow side taper is eliminated by establishing the gap strategy model. The software has developed a function of simulating width adjustment,which can simulate the whole process of width adjustment offline,greatly reduces the risk and cost of experiment.
