    • The present invention provides a magnesia-spinel refractory in which corrosion resistance and slag penetration resistance are significantly improved. The magnesia-spinel refractory is obtained by mixing magnesia granulated powder having a particle diameter of 10 to 150 &mgr;m and alumina powder having a particle diameter of 0.1 to 5 &mgr;m, molding the resultant mixture, and then burning the molded product to form a dense and strong combined structure of periclase and spinel. The mixture of magnesia and alumina contains powders of both components, or a powder of one of the components and a granulated powder of the other component. It is preferable to use a spray dryer method as granulating means, and a hydrostatic pressing method as molding means. These mixtures are used for producing magnesia-spinel protecting tube and crucible, bricks for copper smelting and converting furnaces, and magnesia-spinel protecting tube and crucible for copper smelting and converting furnace slag. In this case, the hydrostatic pressing method is used.
    • 本发明提供了耐腐蚀性和耐熔渣渗透性显着提高的氧化镁 - 尖晶石耐火材料。 通过混合粒径为10〜150μm的氧化镁粒状粉末和粒径为0.1〜5μm的氧化铝粉末,将所得混合物成型,然后将成型体燃烧形成致密的和 强韧组合结构的尖晶石和尖晶石。 氧化镁和氧化铝的混合物含有两种组分的粉末,或其中一种组分的粉末和另一种组分的造粒粉末。 优选使用喷雾干燥法作为造粒机构,以静压压制法作为成型机构。 这些混合物用于生产氧化镁 - 尖晶石保护管和坩埚,用于铜冶炼和转炉的砖,以及用于铜冶炼和转炉炉渣的氧化镁 - 尖晶石保护管和坩埚。 在这种情况下,使用静压法。

    • An evaporative pattern casting method is taught which does not reduce accuracy of an evaporative pattern.The evaporative pattern casting method comprises a part manufacturing process (S2), an assembly process (S4), a sand mold manufacturing process (S6), a molten metal pouring process (S8) and a sand removal process (S12). In the part manufacturing process, the evaporative pattern is manufactured as a plurality of separate parts. In the assembly process, the parts are assembled on a work plane. In the sand mold manufacturing process, the evaporative pattern is covered with sand to form a sand mold without moving the assembled evaporative pattern from the work plane. In the molten metal pouring process, molten metal is poured into the sand mold. In the sand removal process, the sand is removed after the molten metal has solidified. According to this casting method, the sand mold is formed without moving the assembled evaporative pattern from the work plane, and consequently the accuracy of the dimensions at the time of assembly can be maintained.
