Abstract

The invention provides a double-nozzle external heating type intermediate tank which can solve the problem that spatial layout of a casting workshop adopting a traditional intermediate tank heating process cannot adapt to an electromagnetic induction heating intermediate tank with a large distance between molten steel tank casting openings and intermediate tank casting openings. The double-nozzle external heating type intermediate tank comprises an intermediate tank body, molten steel tank casting openings and intermediate tank casting openings are formed in the intermediate tank body, and the lower portions of the intermediate tank casting openings are connected with external crystallizers. The double-nozzle external heating type intermediate tank is characterized in that the number of the molten steel tank casting openings is two, the two molten steel tank casting openings are connected with two sliding nozzles of a molten steel tank through two long nozzles respectively, an electromagnetic induction heating device is installed between the molten steel tank and the intermediate tank body, and one long nozzle is surrounded by the electromagnetic induction heating device.

Description

technical field [0001] The invention relates to the field of continuous casting metallurgical equipment, in particular to a double-nozzle externally heated tundish. Background technique [0002] The tundish is located between the molten steel tank and the crystallizer, and is used to receive the molten steel in the molten steel tank and inject molten steel into the crystallizer. With the development of refining technology outside the furnace, the tundish is not just a simple transition vessel for molten steel, but a continuous metallurgical reactor. At present, the electromagnetic induction heating method of the tundish is regarded as the focus of technological transformation by more and more metallurgical enterprises because of its good heating effect. Traditional tundish structure see figure 1 , which is provided with a pouring port of a molten steel tank, and the molten steel in the molten steel tank is poured into the tundish from the long nozzle through the pouring po...
