瓦房店轴承厂职工贯彻了两参一改三结合的方针,大闹技术革命,用盐炉进行高温快速加热淬火轴承套圈已获得成功。加热时间由原来的30分钟左右缩短至6分钟左右,使产量提高3～4倍。虽然普通机械零件采用快速加热已很普遍,但铬合金滚珠钢制的轴承零件由于须承受复杂、重大的负荷,此因对其显微组织、机械性能等提出较高的要求,一般认为应用快速加热难以保证质量,所以,国内外尚未有使用此种工艺者。现在,这个厂全体职工破除了迷信,解放了思想,发扬了敢想敢干的精 Wafangdian Bearing Factory workers implement the principle of combining the two parameters change three, slaughtering the technical revolution, the use of salt furnace for rapid heating quenching bearing rings have been successful. Heating time from the original 30 minutes or so shortened to about 6 minutes, so that output increased by 3 to 4 times. Although ordinary mechanical parts have been rapidly heated, but due to bear the chromium alloy ball bearing parts due to complex and significant load, due to its microstructure, mechanical properties, etc. put forward higher requirements, the general view that the application of fast It is difficult to ensure the quality of heating, so, at home and abroad have not yet used such craft. Now, all the workers in this factory have got rid of superstition, liberated their thoughts, carried forward the dare to dare to do fine
