Abstract

The invention discloses a crystallizer capable of preventing continuous casting slab defects and belongs to the technical field of crystallizers. The crystallizer capable of preventing the defects comprises a copper plate and a water tank, wherein the copper plate is provided with a cooling water tank, the water tank is provided with a water inlet chamber and a plurality of water outlet chambers, the cooling water tank is communicated with the water inlet chamber and the water outlet chambers, at least one of the plurality of the water outlet chambers is arranged in a meniscus area, and at least one is arranged below the meniscus area. The sectional area of the cooling water tank is decreased in the meniscus area, the water outlet chambers can be connected with a valve, the water flow of the meniscus area is adjusted by controlling the water flow, the cooling intensity of the meniscus area of the crystallizer is reduced, the shrinkage change amplitude of the meniscus area is reduced, formation and growth of continuous casting slabs are more uniform, cracks of the continuous casting slabs are effectively prevented or reduced, and the quality of the continuous casting slabs is improved.

Description

technical field [0001] The invention relates to a defect-preventing crystallizer, which belongs to the technical field of crystallizers, in particular to the technical field of slab and billet continuous casting crystallizers. Background technique [0002] Continuous casting slabs will have various defects, and there are many ways to prevent various defects. Many of the defects are related to the key equipment of continuous casting—the crystallizer. Many defects of continuous casting slabs are generated at the meniscus. Too much and uneven heat export near the meniscus will cause cracks and breakouts, especially as people's requirements for production efficiency, the pulling speed is getting higher and higher, and the heat exported near the meniscus is more intense. The heat transfer is more uneven and the resulting increased chance of cracks and breakouts is more frequent. The heat output of the slab depends on the cooling water of the continuous casting mold. The channel ...
