我厂生产用硅钢片和电工纯铁,在热处理加工中,采用氢气还原处理,以便消除加工应力,降低矫顽力,提高导磁率。所用设备为普通井式炉(RJJ-30-9,RJJ-35-9)和自制的氢气罐。使用过程中,经常出现炉罐与电阻丝接触而被击穿的现象,直接影响生产的正常进行。更严重的是,氢 I plant the production of silicon steel and electrical iron, in the heat treatment process, the use of hydrogen reduction treatment, in order to eliminate the processing stress, reduce coercive force and improve permeability. Equipment used for the ordinary pit furnace (RJJ-30-9, RJJ-35-9) and self-made hydrogen tank. In the course of using, the phenomenon that the furnace canister and the resistance wire come into contact with each other and often breakdown, directly affects the normal production. More seriously, hydrogen
