Abstract: A casting nozzle suitable for production of cast materials of pure magnesium and magnesium alloys. Nozzle (1) is used to feed a molten material between rolls (10) as a casting mold to thereby produce cast material (100), and arranged so that pouring port (4) is positioned between a pair of rolls (10) disposed opposite to each other. This nozzle (1) comprises main body (1a) of an oxide material, such as alumina, and coating layer (3) of a material substantially not containing oxygen, the coating layer (3) superimposed on an inner circumferential surface of the main body (1a) brought into contact with molten material. The main body (1a), as it is not brought into direct contact with molten material by means of the coating layer (3), can avoid any reaction of oxygen contained in the main body (1a) with molten material. Further, casting mold contact portion (2) of the nozzle (1) brought into contact with the rolls (10) is constituted of a heat-insulating material, so that cooling of the molten material within the nozzle (1) by the rolls (10) via the casting mold contact portion (2) can be avoided.
Abstract translation: 适用于生产纯镁和镁合金铸造材料的铸造喷嘴。 喷嘴（1）用于在作为铸模的辊（10）之间输送熔融材料，从而生产铸造材料（100），并且布置成使得倾倒口（4）位于相对设置的一对辊（10）之间 对彼此。 该喷嘴（1）包括氧化物材料的主体（1a），例如氧化铝，以及基本上不含氧的材料的涂层（3），涂层（3）重叠在主体的内周面上 （1a）与熔融材料接触。 主体（1a）通过涂层（3）不与熔融材料直接接触时，可以避免主体（1a）中所含的氧气与熔融材料的任何反应。 此外，与辊（10）接触的喷嘴（1）的铸模接触部分（2）由绝热材料构成，使得通过辊（1）冷却喷嘴（1）内的熔融材料 可以避免通过铸模接触部分（2）10。
