我厂3t电弧炉电极夹头自投产以来,经常发生电极夹紧机构中销轴弯曲变形,从而造成夹紧机构失灵。炉前工人被迫采用斜铁固定电极。每次串电极一退一紧非常费事,烟熏火烤,工作非常艰苦。不仅如此,而且损失很多作业时间,影响生产。针对这个问题我们认真分析了销轴弯曲原因,认为是由于冶炼电流流过销轴而造成的。即有一部分电流是通过导电管、拉杆、销轴、掌板 I plant 3t EAF electrode chuck since its production, the electrode clamping mechanism often occurs in the pin bending deformation, resulting in failure of the clamping mechanism. Workers in front of the furnace were forced to use a fixed iron electrode. It is very troublesome to pull out a series of electrodes every time. The smoke is roasted and the work is very hard. Not only that, but also lost a lot of work time, affecting production. In response to this problem we carefully analyze the reasons for pin bending, that is due to smelting current flow through the pin caused. That part of the current is through the conductive tube, rod, pin, palm plate
