简易气割不锈钢铸件冒口,这是我厂在生产中经过反复实践、认识,掌握的一项工艺。开始,是用钻床钻一个孔,然后用电弧(焊条)切割。这种方法效率很低,成本高,且切口质量差。后来,学习了兄弟厂的经验,采用镀锌铁丝做氧—乙炔焰的助熔剂,切割不锈钢冒口。但是,在切割过程中,锌的氧化物的蒸发对人体危害很大,于是在保证切割质量的前提下,改用低碳铁丝 Simple gas cutting stainless steel casting riser, this is my factory in the production after repeated practice, understanding, master of a craft. To begin, drill a hole with a drill press and cut with an electric arc (electrode). This method is inefficient, costly, and has poor incision quality. Later, I learned the experience of my brother factory, using galvanized iron wire as a flux of oxygen-acetylene flame and cutting stainless steel riser. However, in the cutting process, the zinc oxide evaporation on the human body is very harmful, so to ensure the quality of cut under the premise of using low-carbon wire
