本文主要研究在磁场热处理过程中,如何提高微继电器用永磁合金矫顽力,并从固溶处理、磁场处理和多级回火处理过程中对工艺执行情况、冷却水水温、炉温、磁场回火温度等环节进行分析。结果表明,在热处理过程中,首先要保证设备仪表的灵敏度,执行工艺的严格性,避免人为因素对工艺产生的影响,其次要控制好炉温和保温时间等关键环节,就可以使继电器用永磁合金的磁性能为最佳。

This paper mainly studies how to improve the coercing force of the permanent magnet alloy used for micro relay in the process of magnetic field heat treatment,and analyzes the process execution,cooling water temperature,furnace temperature and magnetic field tempering temperature in the process of solid solution treatment,magnetic field treatment and multistage tempering.The results show that in the heat treatment process,the sensitivity of the equipment and instrument should be guaranteed,the process should be strictly implemented,and the influence of human factors on the process should be avoided.Secondly,it is necessary to control Key links of the temperature of the furnace and the heat preservation time etc.,so that the magnetic energy of the magnetic alloy used by the relay can be optimized.
