一、三十年来的概况自五十年代以采,感应加热在机械工业特别是汽车工业上得到了广泛的应用。以第一汽车制造厂为例,建厂初期,解放牌汽车上采用感应加热的零件仅31种148.5kg。1957年以后,在稳定现生产工艺的同时开展了扩大感应加热在汽车零件上应用的试验研究工作,经过七、八年的努力后,可以采用感应加热的零件已发展到44种。这些零件均经过了装车使用试验,经过多次调查表明效果良好。其使用寿命相当于普通热处理件,有的寿命提高两倍以上,这些试验成果均应用于第二汽车制造厂的产品上。近几年结合我厂产品换型的准备工作,CA141车采用感应加热处
First, the profile of three decades since the fifties to mining, induction heating in the machinery industry, especially the automotive industry has been widely used. To the first car factory, for example, the initial construction, Jiefang card using induction heating parts only 31 kinds of 148.5kg. After 1957, the experimental research on expanding the application of induction heating in automotive parts was carried out while stabilizing the production process. After seven or eight years of hard work, the number of parts that can be heated by induction has grown to 44. These parts have passed the loading test, after many investigations show that the effect is good. Its service life is equivalent to ordinary heat treatment parts, and some life expectancy increased more than twice, these test results are used in the second car factory products. In recent years, combined with the preparation of our plant product change, CA141 car using induction heating
