离心铸造时,用熔剂对金属液进行处理,在熔剂与液态、液固态金属之间发生物理-化学作用,可收到精炼金属液,去除有害杂质、气体以降低金属液被污染程度及减少加工余量的效果。熔剂应以松散、易熔的粉状混合料形式撒在金属液上。在金属液的热量作用下,熔剂被熔化并进行放热反应。熔剂的成分由金属液成分决定,同时要满足下列要求:
Centrifugal casting, the flux liquid metal processing, flux and liquid, liquid and solid metal between the physical and chemical effects, can receive the molten metal to remove harmful impurities, gases to reduce the degree of contamination of liquid metal and reduce processing Effect of margin. The flux should be sprinkled on the molten metal in the form of a loose, fusible powdery mixture. Under the heat of the molten metal, the flux is melted and exothermic. The composition of the flux is determined by the composition of the molten metal, at the same time to meet the following requirements:
