我厂毛坯调质零件,原来都是采用RJX-75-9箱式电炉加热的。由于装出炉都是手工操作,不但劳动强度高,每次出炉淬火和装炉,需要集中10来个劳动力同时进行。而且由于大件在装炉时往往容易把炉底板或炉墙上的电阻丝撞坏,出炉时又需要2～3人同时用钳子夹住工件,放入冷却池,偶一不慎便容易发生工伤事故。在小零件出炉时又因电源已切断容易降温,不能 I plant quenched and tempered parts, the original is the use of RJX-75-9 box furnace heating. Since loading furnaces are all manual operation, not only high labor intensity, each quenching and loading furnace, you need to concentrate 10 to work at the same time. And because of the large pieces of the furnace is often easy to load the furnace floor or furnace wall of the resistance wire crashed bad, baked and need 2 to 3 people at the same time clamp the workpiece with pliers, into the cooling pool, accidentally easy to happen Injury accident. In the small parts baked because the power has been cut off easily, can not
