热处理行业,用的各种吊、挂、夹具,采用稀土处理钢整体铸造是直接获得层数多,壁薄,孔密、形状复杂的且有满意的综合机械性能方法。由于一次铸造成型,生产工艺简便,和钢板焊接工艺比较,有许多突出优点,如节约大量含铬镍等贵重合金,铸件质量好,挂具工作寿命可提高5～9倍。 Heat treatment industry, with a variety of hanging, hanging, fixture, the use of rare earth treatment of steel casting is the direct access to the number of layers, wall thin, dense hole, the shape of complex and satisfactory comprehensive mechanical properties. As a casting molding, the production process is simple, and steel welding process, there are many outstanding advantages, such as saving a large number of expensive chrome-nickel alloy, castings of good quality, hanging work life can be increased 5 to 9 times.
