箱式电阻炉经常因炉底电阻丝的烧断而停炉。特别是用于固体渗碳和退火的箱式电阻炉,由于使用温度高,炉底板易于变形翘曲,加上工件进出炉时运动量大,很容易使金属氧化物掉入炉底电阻丝上,造成短路以至电阻丝烧断,给生产带来了不便。为了解决箱式电阻炉炉底电阻丝的短路问题,我们对箱式电阻炉 Box-type resistance furnace often because of the bottom of the resistance wire blowing off furnace. Especially for solid carburizing and annealing box resistance furnace, due to the use of high temperature, deformation of the furnace floor is easy to warp, coupled with the work of a large amount of movement into and out of the furnace, it is easy to make the metal oxide into the bottom resistance wire, Resulting in short circuit as well as resistance wire blown, bringing inconvenience to the production. In order to solve the box-type resistance furnace bottom resistance wire short circuit problem, we are on the box resistance furnace
