我们在热处理生产中遇到过这样的情况:启动高温盐炉时发现启动电阻断在炉中。虽然这种故障很少出现,但还是避免不了的。以前碰到这种情况,只有请石工用凿子和钢钎慢慢地凿开炉膛内的固体盐,取出断了的启动电阻,安上新的启动电阻进行启动。这种方法费工、费时,炉膛也会受到一定的损坏,并且得停炉几天,影响正常生 We encountered in the production of heat treatment such a situation: Start the high temperature salt furnace start-up resistance found in the furnace. Although this kind of failure is rare, it can not be avoided. In the past encountered such a situation, only the masons with a chisel and drill slowly open the solid salt in the furnace, remove the broken start resistance, install a new start resistance to start. This method of labor, time-consuming, the furnace will be subject to some damage, and have to stop a few days, affecting normal students
