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： The present invention provides a method for producing B4C/Al neutron-absorbing material sheet by continuous cast rolling including the steps of: 1) providing B4C particles and aluminum matrix melt, adding the B4C particles into the aluminum matrix melt while stirring the composite of the B4C particles and the aluminum matrix melt; 2) applying an electromagnetic field to the B4C particle-containing aluminum matrix melt passing through a headbox; 3) applying an ultrasonic vibration to the B4C particle-containing aluminum matrix melt passing through a casting nozzle; and 4) conducing twin roll continuous cast rolling on the B4C particle-containing aluminum matrix melt from the casting nozzle to obtain B4C/Al neutron-absorbing material sheet. The method of the present invention uses twin roll continuous cast rolling under coupled ultrasonic and electromagnetic oscillation to rapidly cool and refine the grains of the solidified composite material and realize uniform distribution of B4C particles in the aluminum matrix.

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。

摘要： A method and apparatus for casting NF metal baths, particularly copper or copper alloys, to produce flat products at least 20 mm thick, ensure melt introduction into a pool while preventing gas pockets or impurities flushing into the melt of a casting mould. The melt continuously flows along a flow-off element from a tundish to a bath level of the mould, at a casting angle of up to 15° and a constant or decreasing rate, and is conducted below a pool surface of the mould without influencing flow rate. Vortexes generated by melt hitting the bath surface are prevented from extending within the mould by a cover surrounding a top surface of the flow-off element. Gaseous components produced when the melt flows, escape via a free space above the flow. Gravity determines a flow rate of the free melt flowing from tundish to molten bath of a revolving strip-casting mould.
