鋳型式連鋳機のノズルを構成した。[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention uses a continuous track mold in which a large number of block molds are connected and wound around rolls separated by a required interval. The endless track-shaped molds are arranged one above the other so that their opposing surfaces move in the same direction to form a mold space, and the molten metal is supplied through a tundish nozzle inserted into the mold space to form a block. In a moving mold continuous casting machine that cools and solidifies molten metal using a mold to cast slabs, a tundish nozzle is attached to a tundish installed at one entrance of the mold space via a semi-cylindrical spacer block. The nozzle of a moving mold type continuous casting machine was constructed using the following methods.
