More Information
Summary:This invention provides a nozzle for casting which is applicable to manufacture cast products of pure magnesium or magnesium alloy. The nozzle 1 supplies molten metal to the place between the rolls 10 served as cast die, so as to manufacture cast products 100, and the nozzle 1 is arranged so that the runner 4 is located between a pair of oppositely arranged rolls 10. The nozzle 1 includes a nozzle body 1a formed by oxides materials such as alumina, and a clad layer 3 contacted with the molten metal and formed inside peripheral surface of the nozzle body 1a by a material which substantially has no oxygen composition. The nozzle body 1a does not contact directly with the molten metal in view of the existence of the clad layer 3, so that the reaction between the oxygen contained in the nozzle body 1a and the molten metal is avoided. Furthermore, if the cast-die contact portion 2 of the nozzle 1, which contact the rolls 10, is formed by heat insulation materials, the cooling of the molten metal within the nozzle
