The effectiveness of the proposal is to improve the integrity of the molten metal by providing 8787 by providing a predetermined width of the cooling zone. Besides, the proposed device makes it possible to refuse use of the bed (s; about the preparation of flat-tip nozzles) makes it possible to ensure smooth change of the intensity of cooling of the ingot surface in accordance with the technological requirements, which improves the quality of the slit on internal defects, as well as reduce the time of preparing the machines for start-up.
