  • Patent number: 8967229
    Abstract: 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.

  • Patent number: 8752612
    Abstract: A lightweight metal mold having a necessary hardness is realized. A plurality of bar-shaped members formed of an evaporative material and a plurality of connecting members formed of an evaporative material are prepared. Each of the connecting members has a spherical shape, and ends of a plurality of the bar-shaped members can be connected to each connecting member. Since a fixing angle of each bar-shaped member with respect to the connecting member can be adjusted freely, a three-dimensional mesh structure having various shapes can be formed. By combining the plurality of bar-shaped members and the plurality of connecting members, an evaporative pattern including the three-dimensional mesh structure can be assembled. By adjusting the shape of the three-dimensional mesh structure, the hardness necessary for the metal mold can be obtained, and the metal mold can be made lighter.

  • Patent number: 6239051
    Abstract: 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.

  • Patent number: 5595948
    Abstract: A refractory is disclosed which contains integrally sintered magnesia particles forming the skeleton of the refractory and a mineral phase of magnesium orthotitanate (Mg.sub.2 TiO.sub.4) formed between the magnesia particles, thus giving an increased erosion resistance. Preferably, the refractory comprises coarse magnesia particles having an average particle diameter of at least 1 mm or a mixture of coarse magnesia particles having an average particle diameter of at least 1 mm and medium magnesia particles having an average particle diameter of 1 to 0.15 mm and 5 to 50 wt. % of magnesium orthotitanate intervening between the magnesia particles. The refractory not only has an excellent durability in a basic atmosphere, but also has a high strength because of combination of the coarse or medium magnesia particles so that it does not tend to deform and has a high durability against thermal shock.
