在我厂的产品中(制氧机,各种氧氨压缩机……等)有很多零件都是用有色金属铜来制造的,但是大家知道:目前我们国家的有色金属很缺少,特别是铜,不仅在工叶上很多地方需要它,而且在价格上比钢和铸铁昂贵得多,为此我们对低碳钢和球墨铸铁进行了抗蚀氮化试验,意欲代替部分铜的制件,从而在保证质量的基础上,节约有色金属和降低产品的成本。 In our products (oxygen machines, various oxygen ammonia compressors, etc.), many parts are made of non-ferrous copper, but as we all know, at present, the non-ferrous metals in our country are scarce, especially copper , Which is not only needed in many places on the leaf but also much more expensive than steel and cast iron, for which we tested for corrosion resistance and nitriding of mild steel and ductile iron, intended to replace part of the copper parts On the basis of ensuring the quality, saving non-ferrous metals and reduce the cost of the product.
