At present, most of the anode aluminum rod and steel claw beam of electrolytic aluminum enterprises mainly use explosive welding for transition connection. According to incomplete statistics, the traditional explosion welding method, the annual cracking rate of the guide bar explosive block is 16-18%, because the traditional welding method is difficult to guarantee the welding quality at the welding joint, and the joint voltage drop is high, which leads to huge energy loss. Therefore, it is particularly important to introduce reliable and efficient steel and aluminum welding technology to reduce maintenance costs and electrolytic production costs.
Aiming at the current situation of the use of explosive welding block, in order to solve the above problems, Zhengzhou Jingwei Technology Industry Co., Ltd, after in-depth research and a large number of experiments, has developed the JW-51A steel and aluminum welding process and the supporting steel and aluminum welding production line, which realizes that there is no need for the explosive welding block for the welding of the anode rod and the steel claw beam, and the quality of the weld is more reliable and stable. Since the technology entered the field application in 2015, it has been put into application in many electrolytic aluminum enterprises such as Aluminum Corporation of China ,Baise Yinhai, Gansu Zhongrui, Neimeng Jinlian, Xinjiang branch of East Hope , Xinfa Group, etc. The use effect is good, and the power saving advantage is obvious.
