摘要： A casting nozzle suited to manufacture a casting material of pure magnesium or magnesium alloy is provided. A nozzle is utilized to manufacture a casting material by supplying molten metal to a portion between rolls which become a casting die, and arranged so that a pouring port is located between a pair of rolls opposed to other. This nozzle includes a main body formed of oxide material such as alumina, and a coating layer which is provided on the inner surface of the main body which comes into contact the molten metal, and formed of material that does not include oxygen substantially. Since the main body does not come into direct contact with the molten metal due to the coating layer, it is possible to prevent oxygen included in the main body from reacting with the molten metal. Further, in the nozzle, a casting die contact portion which comes into contact with the rollers is formed of thermal insulation material, whereby it is prevented that the molten metal in the nozzle is cooled through the casting die contact portion by the rollers.

摘要翻译： 提供了适用于制造纯镁或镁合金铸造材料的铸造喷嘴。 通过将熔融金属供给到成为铸模的辊之间的部分，喷嘴用于制造铸造材料，并且布置成使得倾倒口位于与另一个相对的一对辊之间。 该喷嘴包括由诸如氧化铝的氧化物材料形成的主体，以及设置在主体的与熔融金属接触的内表面上并且基本上不包括氧的材料形成的涂层。 由于主体由于涂层而不与熔融金属直接接触，所以可以防止主体中包含的氧与熔融金属反应。 此外，在喷嘴中，与辊接触的铸模接触部分由绝热材料形成，从而防止喷嘴中的熔融金属通过辊通过铸模接触部分而被冷却。
