提高铸铝转子的质量是改善异步鼠笼型电机性能的重要途径之一。中小型电机产品质量分等规定对铸铝化学成分(浇口)列为内容之一。上海电机公司组织了行业攻关,但仍是质量不稳定的老大难问题之一。根据行业考核要求,转子铸铝铝液铁和硅含量总和不大于0.9%。我厂实际生产中达不到此项要求,影响了电机的质量。分析造成铝液化学成分超差的原因,主要是由于铸铁坩埚的耐腐蚀性能差和高温铝
Improving the quality of cast aluminum rotor is one of the important ways to improve the performance of asynchronous squirrel cage motor. Small and medium motor product quality classification requirements on the chemical composition of cast aluminum (gate) as one of the contents. Shanghai Electric Company organized the industrial research, but it is still one of the most difficult problems of unstable quality. According to the requirements of the industry assessment, the rotor aluminum-aluminum liquid iron and silicon content of not more than 0.9%. I plant the actual production of less than this requirement, affecting the quality of the motor. Analysis of aluminum liquid chemical composition of the reasons for the ultra-poor, mainly due to poor corrosion resistance of cast iron crucible and high-temperature aluminum
