Abstract

The invention relates to a circulating cooling type continuous casting crystallizer. The circulating cooling type continuous casting crystallizer comprises a crystallizer body, an outer layer housingand a cooling box, wherein bosses are arranged at the two ends of the crystallizer body; the bosses are sleeved with the outer layer housing; a closed first cooling channel is formed among the crystallizer body, the bosses and the outer layer housing; the bosses are provided with a first water inlet and a first water outlet which communicate with the first cooling channel; a second cooling channelis arranged in the outer layer housing; the two end faces of the outer layer housing are provided with a second water inlet and a second water outlet which communicate with the second cooling channel; a snakelike heat exchange pipe is arranged in the cooling box; an air blower is arranged on the side, close to a water outlet pipe, of the cooling box; and an exhaust fan is arranged on the side, close to a water inlet pipe, of the cooling box. According to the crystallizer, the two cooling channels are adopted, the heat dissipation efficiency is improved, heat dissipation is more uniform, the crystallization speed of the crystallizer is kept consistent, and the crystallization effect is guaranteed. Cooling water is recycled, water resource utilization is reduced, cost is reduced, and the system integrity and system running stability are improved.

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...
