铜模底板修补方法的焊接工艺研究

Research on Welding of Copper Mold Base Platfe Method

某火法冶炼系统铜模底板在生产铜阳极板的浇铸过程中频繁出现模层表面开裂、成片脱落等问题。本文针对铜模底板出现此类问题的原因,以及后续铜模底板修补过程、修补工艺的控制展开研究。通过冷焊法与栽丝焊的结合,在对目前所修补的铜模进行了数十次试验后,最终总结出一套最适合的焊接工艺及焊接参数,希望能为日后生产中出现的类似问题提供一种有效的解决方法。

During the casting process of the copper anode plate,the surface of the die layer is cracked and the sheet falls off frequently.In this paper,the reasons for this kind of problems of copper die bottom plate,as well as the following copper die repair process,repair process control.Through the combination of cold welding and wire planting welding,after dozens of tests on the copper mold repaired at present,a set of the most suitable welding process and welding parameters are finally concluded,hoping to provide an effective solution for similar problems in production in the future.
