Embodiment 1

[0037] Embodiment one: as figure 1 As shown, a continuous casting mold includes a mold copper tube 1 and a mold water tank 2 that supports the mold copper tube and cools the water. The mold water tank is provided with a water inlet chamber 3 and two The outlet chambers are respectively outlet chamber one 4a and outlet chamber two 4b, the water inlet chamber 3 communicates with the water inlet pipe 5, the outlet chamber one 4a communicates with the outlet pipe one 6a, and the outlet chamber two 4b communicates with the outlet pipe two 6b communicates, and a valve 7 is set on the outlet pipe two 6b, and the outlet pipe two 6b communicates with the valve 7, and the crystallizer water tank 2 is provided with a central depression, a peripheral protrusion with a sealing groove 8 and a sealing ring 9, The contact surface with the crystallizer copper tube 1 forms a peripheral seal, and there is a gap in the middle of the water-cooled heat exchange channel 10. The first water outlet ch...

Embodiment 2

[0038] Embodiment two: if figure 2As shown, a continuous casting crystallizer includes a mold copper tube 1 and a crystallizer water tank 2 that supports the mold copper tube and cools the water through it. The crystallizer water tank 2 is provided with a depression with a step in the middle, The peripheral protrusion has a sealing groove 8 and a sealing ring 9, forming a peripheral seal with the contact surface of the mold copper tube 1, and a water-cooled heat exchange channel with a step gap in the middle, and the depression with a step in the middle corresponds to the meniscus area The depression corresponding to the meniscus is relatively shallow, the depression below the meniscus is relatively deep, the water-cooling heat exchange channel 10b corresponding to the meniscus area is relatively small, and the water-cooling heat exchange channel 10a corresponding to the meniscus area is relatively large , the crystallizer water tank is provided with a water inlet chamber 3 a...

Embodiment 3

[0039] Embodiment three: as image 3 As shown, a continuous casting crystallizer includes a crystallizer copper plate 1 and a mold water tank that supports the mold copper plate and cools water through it. The water tank back plate 2b that can be quickly replaced is added between them. The water tank back plate 2b is provided with a water inlet chamber 3 and two water outlet chambers, namely the water outlet chamber one 4a and the water outlet chamber two 4b, that is, the crystallizer water tank inlet The water chamber and the water outlet chamber of the crystallizer water tank are transferred to the corresponding position of the water tank back plate, the water inlet chamber 3 is communicated with the water tank 2a and the water inlet pipe 5, and the water outlet chamber-4a is communicated with the water tank 2a and the water outlet pipe-6a, so The second water outlet chamber 4b is communicated with the water tank 2a and the second water outlet pipe 6b, the second water outle...

Abstract

The invention discloses a crystallizer capable of preventing flaws, and belongs to the technical field of the crystallizers. The crystallizer comprises a copper plate and a water tank; the water tank is provided with a water inlet chamber and a plurality of water outlet chambers; the water tank or the copper plate is provided with a middle pit for forming a water-cooling heat exchange channel; the water-cooling heat exchange channel communicates with the water inlet chamber and the water outlet chambers; at least one of the water outlet chambers is arranged in a meniscus area; and at least one of the water outlet chambers is arranged below the meniscus area. With the adoption of the structure, the cooling water amount of the meniscus area, the cooling intensity of the meniscus area and the heat flux density are reduced, the meniscus area is extended, the heat conduction is relatively uniform, no cooling water amount is recued as to the crystallizer wholly, the effects of reducing the cooling intensity of the meniscus area of the crystallizer and reducing the shrinkage variation amplitude of the meniscus area are exerted, the forming and growth of a continuous casting billet are more uniform, the continuous casting billet is prevented from generating the flaws or the number of the flaws of the continuous casting billet are reduced effectively, and the quality of the continuous casting billet is improved.

Description

technical field [0001] The invention relates to a continuous casting crystallizer, which belongs to the technical field of crystallizers, in particular to the technical field of continuous casting crystallizers for slabs, square billets, round billets, special-shaped billets and ultra-thin slabs. 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 de...
