鉴于电石墨电极的耐磨性较差,电极与工件接触端部的锥度不易保持,影响了淬火质量,需要经常修复电极。生产效率太低,用于正产品上是不能满足要求的。遵照毛主席不断革命的教导,必须另寻新途。同时,也受到了其他一些资料的启发,我们认为采用滚轮式电极是个好办法。 In view of the poor wear resistance of the electrographite electrode, the taper of the contact end of the electrode and the workpiece is not easy to maintain, which affects the quenching quality and requires frequent repair of the electrode. The production efficiency is too low for positive products that cannot meet the requirements. In keeping with Chairman Mao’s constant revolutionary teaching, we must find new ways. At the same time, inspired by other data, we believe that using a roller electrode is a good idea.
