我厂盐浴炉电极材料是A3钢,铜排材料是黄铜。电极与铜排的连接靠螺栓压紧。由于电极与铜排连接部分通水冷却易吸湿,加上长时间受熔盐蒸气和盐沫飞溅的锈蚀,电极与铜排接触部分形成许多麻坑,造成接触不良,以至工作时发生打火现象,严重时烧损螺栓,造成停炉检修。为了解决这个问题,我们多次打磨电极与铜排接触面和更换螺栓,但一直没有得到解决。后来,我们在电极与铜排接触部分涂上一层大黄油便解决 Salt bath furnace electrode material is A3 steel, brass material is brass. The connection between the electrode and the copper bar is pressed by the bolt. Due to the electrode and the copper part of the water cooling and easy to absorb moisture, coupled with a long time by molten salt vapor and salt splash rust, the electrode and the copper part of the contact part of the formation of a number of Ma Hang, resulting in poor contact, and even the phenomenon of ignition , Severe burnt bolts, causing shutdown furnace maintenance. In order to solve this problem, we repeatedly polish the electrode and the copper bar contact surface and replace the bolt, but has not been solved. Later, we are in the electrode and the copper part of the contact area coated with a layer of butter will be solved
