我厂毛胚调质另件,原来都是采用仿苏75Kn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,每次出炉和装炉,需要集中10余个劳动力同时进行。而且由于大件在装炉时往往容易把炉底板和或炉壁上的电阻丝撞坏,出炉时又需要2～3人同时用钳子夹住工件,放入冷却池,偶一慎便容易发生工伤事故,在小另件出炉时又因电源已切断容易降温,不能保证淬火质量,在钳入水缸淬火时还容易漏入缸底,打捞困难,造成损失,此外,因劳动
I plant the other parts of the embryo quenching, the original is the use of imitation Su-75Kn box-type electric heating, as a result of loading furnace are manual operation, not only high labor intensity, each baked and furnace, you need to concentrate more than 10 labor at the same time. And because of the large pieces of the furnace is often easy to load the furnace floor and the furnace or the resistance of the wire on the damage, the furnace also need 2 to 3 people at the same time clamp the workpiece with pliers, into the cooling pool, even a prudential easy to happen Work-related accidents, small parts in the baked out because of the power supply has been cut off easily cooled, can not guarantee the quenching quality, when the clamp into the cylinder quenching can easily leak into the bottom, salvage difficulties, resulting in losses, in addition, due to labor
