| 在精密铸造中，我们可以使用到不锈钢、碳钢、合金钢等，它们都是可以用来进行精密铸造的。不过具体的，还是要由具体情况来进行选择。但是不管哪种材质在使用中都难免会发生锈蚀，在加工的时候可以做哪些处理来减少锈蚀的发生呢？ In precision casting, we can use stainless steel, carbon steel, alloy steel, etc. They can be used for precision casting. However, it is still necessary to choose from specific circumstances. But no matter which material is used, rust will inevitably occur. What can be done to reduce the occurrence of rust in processing? 金属或合金在大气中因为氧、水分、酸、盐及湿润空气导致的腐蚀或变色称为生锈或锈蚀，它可以使具有很高强度的金属表层变成强度很低的化合物。为此，熔模铸件常需进行中期防锈处置。防锈的办法，通常选用水剂防锈或油料防锈。无论选用哪一种办法防锈，铸件预先都要通过洗刷，铲除表面的污浊物，并促进其生成钝化膜。洗刷液的成分、温度及用处。铸件洗刷后要用热的、枯燥的压缩空气吹干，随即进行防锈处置。 Corrosion or discoloration of metals or alloys in the atmosphere caused by oxygen, moisture, acid, salt and wet air is called rusting or rusting, which can turn high-strength metal surface into low-strength compounds. To this end, investment casting often needs to be treated in the medium term. Rust preventive methods usually use water agents to prevent rust or oil to rust. No matter which method is chosen to prevent rust, the casting must be washed in advance to remove the surface dirt and promote the formation of passive film. The ingredients, temperature and usage of the cleaning fluid. After the casting is washed, hot and dry compressed air is used to blow dry. Then rust treatment is carried out. |
