在压力筒内空气强压下结晶的方法用于铸铝合金,在我国还是一项年轻的技术,但经过几年来的生产实践证明它是一项行之有效的先进工艺。在我国的一些工厂中,小型铝合金铸件采用压力结晶法的已比较多,对于大型铝合金铸件采用此种压力结晶方法的仅有少数几个大工厂,但均系按照国外设计仿造,设备庞大复杂,占用生产面积较大,需要国家较大投资。
In the pressure cylinder under the pressure of air crystallization method for casting aluminum alloy in our country is still a young technology, but after several years of production practice has proved it is an effective advanced technology. In some factories in our country, there are quite a few small aluminum alloy castings adopting the pressure crystallization method, and there are only a few large factories adopting this pressure crystallization method for the large aluminum alloy castings. However, all of them are designed according to foreign designs and have huge equipment Complex, occupy a larger area of production, the need for greater national investment.
