上海工具厂用辐射高温计控制盐浴炉温度已有20余年历史,工具淬火后的金相、硬度均能稳定地保持在较好水平,由于控温不当或感温器故障而造成过热报废的事故极为少见。作者在本文中介绍了辐射感温器的优点;合理安装、使用的常识和经验;使用和控温时的一些改进、革新;稳定性试验的数据;盐浴黑度系数问题、盐雾干扰等问题的讨论和校温方法等等。
Shanghai Tool Factory with a radiation pyrometer temperature control salt bath furnace has more than 20 years of history, the tool after quenching the metallographic, hardness can be maintained at a good stable level, due to improper temperature control or thermal failure caused by overheating scrapped The accident is extremely rare. The author introduces the advantages of radiant temperature sensor in this article; common sense and experience of reasonable installation and use; some improvements and innovations when using and controlling temperature; data of stability test; blackness coefficient of salt bath, salt spray interference, etc. The discussion of the problem and the school temperature method and so on.
