ZG50熔模铸钢件省工省料,价格低廉,常用于制造枪械中形状复杂、负载较低的固定件,在生产上得到了较为广泛的运用。 其主要工艺路线是:浇铸成型(浇铸温度1480～1540℃、模壳温度550～750℃); ZG50 investment cast steel saving labor and material, low prices, commonly used in the manufacture of firearms in complex shape, the lower the load of fixed parts, in the production has been more widely used. The main process route is: casting (casting temperature 1480 ~ 1540 ℃, die shell temperature 550 ~ 750 ℃);
