箱式电炉和台车式电炉底板在使用过程中不可避免地要损坏,并多以局部开裂的形式出现。一旦炉底板开裂就要即时换掉,否则工件的氧化皮通过裂缝掉到炉底电阻丝上,很容易使电阻丝因短路烧毁。炉底板材料价格较贵,为降低生产成本,我厂采取下述办法对破损的炉底板进行修复。 先将破损的炉底板放在刚出炉的退火罐 Box furnace and trolley furnace floor in the course of the inevitable to be damaged, and mostly in the form of local cracking. Once the furnace floor cracking will be replaced immediately, or the workpiece oxide scale through the cracks fell to the furnace resistance wire, it is easy to make the resistance wire burned due to short circuit. Furnace floor material prices are more expensive, in order to reduce production costs, I plant the following methods to repair the damaged furnace floor. First broken furnace floor on the just released annealing tank
