Adjustable mould for horizontal continuous casting apparatus.

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. <IMAGE>
