摘要： An adjustable mold for a horizontal continuous casting apparatus comprises a tundish (2), a cylindrical-shaped mold (3) tightly joined to the tundish, and a mold (3). The mold (3) further comprises an airtight cylindrical-shaped mold tube (12) and an adjustable mold (13) divided into a plural number of cooling plates (18A-18D) in the direction of the periphery of the casting section and arranged after the airtight cylindrical-shaped mold tube (12), and a member of consumable material (17A-17D) covers the inner surfaces of the cooling plates (18A-18D). The plural number of cooling plates (18A-18D) of the adjustable mold (13) are able to move in the direction of the casting section radius. The inlet ends of each of the cooling plates (18A-18D) of the adjustable mold (13) are supported by support shafts (19A-19D) that can have its position determined so that an inner diameter (d) of an outlet end of the airtight cylindrical-shaped mold tube (12) and an inner diameter (d1) of an inlet end of the adjustable mold (13) can be brought into agreement. Thus, the plural number of cooling plates (18A-18D) of the adjustable mold (13) can swivel in the direction of the casting section radius around the support shaft (19) by the reciprocating movement of a hydraulic cylinder (23A-23D) provided to connect the side wall portion of a cooling box frame (14) of the airtight cylindrical-shaped mold tube (12) and the outlet end portion of each of the cooling plates (18A-18D) of the adjustable mold (13). In addition, an inner diameter of the adjustable mold (104a) can be adjusted and fixed by a position adjuster (118) provided to the inlet end of the adjustable mold (104a) and the outlet end of the adjustable mold can (104a) be moved in the direction of the casting section radius by a hydraulic cylinder (113) provided in the direction of the casting section radius.

摘要： A continuous casting method comprises continuously supplying molten metal from a tundish to a cooled mold having an inlet and an outlet at least through a break ring, forming a cast section by continuously cooling the molten metal in the mold and starting the solidification of the molten metal below its surface, and intermittently withdrawing the cast section with respect to the mold through its outlet. During continuous casting, a sealing gas having a pressure higher than atmospheric and being soluble in the molten metal is invariable supplied to the entirety of the contact area of the mold and the break ring.

摘要： PURPOSE:To improve the quality and the yield of a cast billet by inserting an annular gasket between an upstream mold and downstream mold and supplying pressurized gas soluble to cast metal into inside of the annular gasket. CONSTITUTION:A horizontal continuous casting apparatus is constituted by communicating a tundish with the mold through a nozzle 13 and connecting plural water cooling molds along the direction of drawing cast billet C. Then, the annular gasket 33 is inserted between the upstream side mold 19 and the downstream side mold 21 so as to surround the cast billet C. The pressurized gas soluble to the cast metal is supplied to inside of the annular gasket 33 from an introducing pipe 37. By this method, flaw removal work can be saved.

摘要： PURPOSE:To uniformly cool a cast billet while shifting according to solidified shrinkage and to obtain the cast billet having good quality by adjusting an inner diameter size with a positional adjusting device disposed at the inlet of an adjustable mold and making an outlet shiftable in a radius direction with a hydraulic cylinder. CONSTITUTION:The inner diameter size of molds is adjusted and fixed with screws 18 in the positional adjusting device disposed at the inlet of adjustable molds 4a, 4b divided into four elements in the radius direction of a casting cross section following to a cylindrical mold 2 in a continuous casting device tightly connecting a tundish 1 and the cylindrical mold 2. Successively, by making the outlet of adjustable molds 4a, 4b shiftable to the radius direction of casting cross section with the hydraulic cylinder 13 disposed in the radius direction of casting cross section, the cast billet comes into contact with each element and uniformly cooled and the cast billet having good quality can be obtd.
