摘　　要：某钢铁厂冷轧连退产线经常发生焊机焊接温度低报警故障,导致连续产线带钢重焊甚至停机处理,影响产线作业效率,同时产出大量的带出品,给公司带来了严重的经济损失。阐述了焊机焊接完带钢后焊接温度曲线低报警事故,首先介绍了窄搭接焊机的基本原理和影响窄搭接焊机焊接的关键参数。其次对连退产线频发的焊机焊接温度曲线低报警问题进行原因分析,分析出电极轮安装位置精度和电极轮表面状态两个主要原因。再次对电极轮安装位置精度和电极轮表面状态采取进一步改进措施。最后对窄搭接焊机焊接温度低报警问题进行总结。The alarm fault of low welding temperature of welding machine often occurs in the cold rolling continuous return production line of an iron and steel plant,which leads to the rewelding or even shutdown of the strip steel of the continuous production line,affects the operation efficiency of the production line,and produces a large number of strip products at the same time,which has brought serious economic losses to the company.This article elaborates on the low welding temperature curve alarm accident of welding machine after welding the strip steel.Firstly,it introduces the basic principle of narrow lap welding machine and the key parameters that affect its welding.Secondly,it analyzes the causes of the low alarm of the welding temperature curve of the welding machine which occurs frequently in the continuous return production line,and analyzes the two main reasons:the accuracy of the installation position of the electrode wheel and the surface state of the electrode wheel.Thirdly,further improvement measures are taken for the installation position accuracy of the electrode wheel and the surface state of the electrode wheel.Finally,the alarm problem of low welding temperature of narrow lap welding machine is summarized.
