The invention relates to a circulating cooling continuous casting crystallizer, which comprises a crystallizer body, an outer shell and a cooling box. Bosses are arranged at both ends of the crystallizer body, and the outer shell is sleeved on the bosses. The crystallizer A closed first cooling channel is formed between the body, the boss and the outer shell, and the boss is respectively provided with a first water inlet and a first water outlet communicating with the first cooling channel; the outer shell is provided with a second Cooling channel, the two ends of the outer casing are respectively provided with a second water inlet and a second water outlet connected to the second cooling channel; a serpentine heat exchange tube is provided in the cooling box; a side of the cooling box near the water outlet pipe is provided There is a blower, and the side of the cooling box near the water inlet pipe is provided with an exhaust fan. The crystallizer of the present invention adopts two cooling passages to improve the heat dissipation efficiency, make the heat dissipation more uniform, keep the crystallization speed of the crystallizer consistent, and ensure the crystallization effect. Cooling water recycling is adopted to reduce the utilization of water resources, reduce costs, and improve the integrity of the system and the stability of system operation.
Description
technical field [0001] The invention relates to the technical field of crystallizers, in particular to a circulating cooling type continuous casting crystallizer. Background technique [0002] The continuous casting mold is a continuous casting equipment that accepts the molten steel poured from the middle and solidifies it into a solid billet shell according to the specified shape. It is an important equipment in the continuous casting system and is mainly used to cool the molten steel in the mold. The molten steel is formed into a slab for output, and its structure plays a decisive role in the quality of the slab and the production capacity of the casting machine. The cooling of the molten steel by the mold is realized by continuously sending cold water into the mold, but the heat dissipation of the current mold is not uniform, the heat dissipation efficiency is not high, the crystallization speed of the mold cannot be kept consistent, and the cooling water cannot be recyc...
