  • Patent number: 7984750
    Abstract: A sand core is prepared for use in defining a surface of a cast metal article. The core is formed of sand particles bonded with a polyurethane resin, preferably a polyol moiety-containing polyurethane resin. An alkali metal hydroxide, and optionally a glycol, is mixed with precursors of the polyurethane before they are mixed with sand particles for molding and curing the core. The hydroxide and glycol may be encapsulated to prevent interference with core molding. The hydroxide and glycol is distributed in the polyurethane binder resin and used to reduce the decomposition temperature of the core binder during casting. This practice is particularly useful in removing core sand from castings of light metal, lower casting temperature metal alloys.

  • Patent number: 7882887
    Abstract: A method and apparatus is disclosed for casting metals in a DC mold to form an ingot or product having at least two layers formed by sequential solidification. The apparatus has at least one cooled divider wall at the entry end portion of the mold to divide the entry end portion into at least two feed chambers. Metal is fed to the chambers to form an inner layer and at least one outer layer. The divider wall has a metal-contacting surface for contacting the metal for the at least one outer layer, the surface being arranged at an angle sloping away from the metal for the outer layer in a downward direction. The angle is larger at the center of the divider wall compared to the angle adjacent to each longitudinal end thereof. The apparatus is suitable for co-casting metals having similar coefficients of contraction to minimize problems of adhesion between the layers of a resulting ingot or rolled products produced therefrom.
