摘要： PROBLEM TO BE SOLVED: To improve the workability and to prevent the penetrating phenomenon of molten metal by arranging a slidable closed member at a gap between the inner surface of a mold and the surroundings of a molten metal pouring nozzle and also, a gas passage in the wall of the pouring nozzle and opening a gas injecting hole into the gap. SOLUTION: The slidable closed member 20 is arranged at the gap between the square inner surface of the mold and the surroundings of the molten metal pouring nozzle 3 and also, the gas passage 16 is arranged in the longitudinal direction in the wall of the pouring nozzle 3 and the gas injecting hole 14 is opened into the gap. Molten metal static pressure Ph detected with a molten metal surface level sensor 19 and gas pressure Pb in the gap 15 detected with a gas pressure sensor 18 are comparison-operated with a computing element 21. The pressure of the gas G is controlled so that the Ph is almost equalized to the Pb with a pressure control unit 22. By this constitution, the trouble, such as the penetration of molten metal or the entrapment of gas caused by the excess or the shortage of loaded pressure can be prevented.

摘要： PURPOSE:To obtain a high m.p. metal-contg. Al base alloy with a uniform compsn. in which the segregation of the gravity of intermetallic compounds such as Al3Ta is prevented and the compositional uniformity of a high m.p. metal-contg. Al base alloy material is remarkably improved and suitable, e.g., as a sputtering target material for forming a reflecting film for optical media, a wiring film for a liquid crystal display or the like. CONSTITUTION:At the time of melting and casting the Al base alloy contg. high m.p. metals such as Ta, Ti, Zr, Hf, V, Nb, Cr, W, Mo, Y and Mn, the melting is executed at the liquidus temp. of the alloy or above. The temp. of the molten metal in a mold till the completion of the pouring at the time of pouring the molten metal into the mold and executing casting is held to a temp. at which the intermetallic compounds of the high m.p. metals and Al are not formed in the molten metal in the mold at least at a time when the pouring is completed. After the completion of the pouring, the molten metal in the mold is rapidly cooled and is solidified.

摘要： PROBLEM TO BE SOLVED: To prevent penetration of molten metal by forming a pair of side gates of a self sliding material splitting, the side gates to right and left ones at the casting line, providing a pressing means to independently press aside a bottom part of the split side gates and a roll to reduce a gap between the side gates and the roll. SOLUTION: A continuous casting equipment directly manufactures a metallic sheet by passing a molten metal in a gap between rolls. Split side gates are split into two or more parts in a direction orthogonal to the casting direction, and each part is independently and movably mounted in the axial direction of the rolls. A self sliding material is preferably graphite. After bottom part of the side gates 10 is machined to the same curvature as that of a circumferential surface of rolls 1a, 1b, and split in right and left parts relative to the casting line, and further split into two. Split side gates 10a, 10b, 10c, 10d are mounted on a side gate support body 7, and a roll circumferential surface is independently pressed by springs 8a, 8b, 8c, 8d and holding plates 9a, 9b, 9c and 9d. The side gates are prevented from being broken, and the wear is reduced.
