CASTING SLEEVE WITH WILLIAMS CORE |
摘要 |
A sleeve (110) for use in metal casting has a sleeve body, where a longitudinal axis (B) has a side wall (116) formed around it, defining a sleeve interior. The sleeve body is open at a first end (118). A core (120) is formed integrally along an interior surface extends into the sleeve interior. The sleeve body and the core are formed of a gas-permeable refractory material. At least the core contains material for generating heat when heated by a molten metal. The core extends along the side wall from the first end to a second end. The core has a width that is constant or decreases in a radial direction away from the side wall, especially with a triangular profile, with a base thereof in contact with the side wall. The sleeve body is cylindrical or frustoconical, with a diameter that decreases from the open first end. |
