NOZZLE FOR CASTING

摘要

A nozzle for casting fixed to a molten metal reservoir storing the molten metal of an aluminum alloy or a magnesium alloy and feeding the molten metal to a movable mold for continuous casting. The tip of the nozzle is formed of a highly heat conductive material having a heat conductivity of 0.2 W/mK or higher or a highly elastic material having an elastic modulus of 5000 MPa or higher. Since the tip of the nozzle is formed of the highly heat conductive material, the nonuniformity of solidification of the molten metal can be reduced to improve the properties of the surface of the molten metal. By forming the tip of the nozzle of the highly elastic material having excellent elastic deformability and reducing a clearance between the outer peripheral edge tip of the nozzle and the movable mold, a casting material having excellent surface quality can be provided.
