氧-炔焰切割法一般只能适用于碳钢和低合金钢,并不能应用在所有的金属中。对于很多用途很广的重要金属,例如不锈钢、高铬钢、铸铁和有色金属等都不能用它来切割;因为在切割这些金属的时候,或则生成一层很难熔化的氧化物(对不锈钢、高铬钢),从而使切割过程发生困难;或则由于操作不答易控制(对铸铁),不能得到良好的切割质量。苏联已经试验成功 Oxygen-acetylene flame cutting method generally only applies to carbon steel and low alloy steel, and can not be used in all metals. Do not use it to cut a lot of important metals such as stainless steel, high-chrome steel, cast iron and non-ferrous metals because they are widely used, because when cutting these metals, they produce a layer of refractory oxide , High-chrome steel), so that the cutting process difficult; or because of the operation is not easy to control (on cast iron), can not get a good cutting quality. The Soviet Union has been successfully tested
