随着工农业的发展,铝合金铸件普遍应用,特别是汽车工业中如铝活塞、铝制汽缸盖等每年需要量是很大的。在生产铝合金活塞和铝合金汽缸盖时有很多铝屑,同时每年的废活塞及废汽缸盖数量也不少,如何利用废料来生产铝合金汽缸盖为国家节约大量的资金是一个重要问题。我厂采取二次熔炼回收废杂铝,一年回收可利用的铝合
With the development of industry and agriculture, aluminum alloy castings are widely used, especially in the automotive industry such as aluminum pistons, aluminum cylinder heads and other annual requirements are great. In the production of aluminum alloy piston and aluminum cylinder head when there are a lot of aluminum scrap, while the annual number of waste piston and waste cylinder head is also not how to use waste to produce aluminum cylinder head for the country to save a lot of money is an important issue. I plant to take two smelting waste recycling miscellaneous aluminum, available aluminum recycling a year
