The conventional belt-type thin slab continuous casting machine is
As described in Publication No. 60-103145, in order to immerse the tip of a cylindrical or duct-shaped molten steel nozzle into molten steel in a mold, the uppermost part of the belt that forms part of the mold is widened. Then, a so-called fan-shaped short-side mold with a structure in which the curvature is gradually changed from the top and the belt interval is narrowed to a predetermined width is used, or a cylindrical or duct mold is used as described in JP-A-60-152347. The type of molten steel nozzle was a so-called open nozzle whose tip was not immersed in the molten steel, and a so-called straight short-side mold was used in which the belt interval was maintained at a predetermined width from the top.

Among the above-mentioned conventional technologies, the fan-shaped short-side mold described in JP-A No. 60-103145 prevents the generation of solidification shells from molten steel on the fan-shaped short-side side plates that constitute the mold together with the belt and have curvature. On the other hand, the open nozzle disclosed in Japanese Patent Application Laid-Open No. 152347/1980 has the problem of fluctuations in the molten steel level (the free top surface of the molten steel) in the mold and the incorporation of air bubbles into the molten steel. It was becoming a problem. The cause of these problems is that conventional molten steel nozzles are either cylindrical or duct-shaped and supply molten steel from inside the nozzle, which makes it impossible to make the nozzle diameter extremely small, which makes continuous thin slab casting difficult. This is because it is not inherently suitable for the machine.

The plate type molten steel nozzle is immersed in the molten steel in the mold, and the molten steel is supplied to the mold as a liquid film along the outer surface of the plate of the nozzle. As a result, the supplied molten steel is quietly supplied into the molten steel in the mold without falling, so that the molten steel level does not fluctuate or air bubbles are mixed into the molten steel. In addition, the thickness of the nozzle plate can be made as thin as necessary within the required strength range, making it possible to further narrow the belt spacing in straight short side molds, making it possible to obtain ultra-thin slabs using a continuous thin slab casting machine. becomes.
