Problems solved by technology

However, the copper tube of the continuous casting tubular crystallizer is generally thin, and the copper tube and the water jacket are only fixed with flanges at the top and bottom of the crystallizer to prevent deformation of the top and bottom, and there is no combination between the middle part of the copper tube and the water jacket It is connected and fixed with bolts like the cast mold, and because the height of the continuous casting tubular mold is relatively large, generally about 0.9m, it is easy to cause relatively large copper tubes in the middle of the copper tube under the action of steel hydros

Abstract

The invention belongs to the field of metallurgical equipment, and particularly discloses a continuous casting tube type crystallizer which can effectively reduce the middle deformation amount of theexisting copper tube. The continuous casting tube type crystallizer comprises a copper tube, a water jacket and a copper strip; the copper tube is rectangular; adjacent side surfaces on the copper tube are in smooth transition connection through an arc part; the water jacket is arranged on the copper tube in a sleeving manner; a water seam is formed between the water jacket and the copper tube; the copper strip is arranged on the outer surface of the arc part in the height direction of the copper tube; and the outer surface of the copper strip is an arc-shaped surface and is adhered to the inner surface of the water jacket. According to the continuous casting tube type crystallizer, the copper strip is arranged on the outer surface of the arc part of the copper in the height direction of the copper tube, so that on one hand, the structural strength of the copper tube can be strengthened, and on the other hand, the copper strip is closely matched with the water jacket; therefore, the deformation amount in the copper tube can be remarkably reduced; the quality of the produced continuous casting blank can be improved; and the service life of the crystallizer can be prolonged.

Description

Technical field [0001] The invention belongs to the field of metallurgical equipment, and specifically relates to a continuous casting tube type crystallizer. Background technique [0002] The main body of the continuous casting tube crystallizer is directly formed by a copper tube, and the copper tube is covered with a water jacket, and the cooling water contacts the cold surface of the entire copper tube. Compared with the combined mold, the continuous casting tube mold has no corner seams between the copper plates, and the corner water seam arrangement is more reasonable, the cooling of the cast slab is more uniform, and the corner quality is better. However, the copper tube of the continuous casting tube mold is generally thin. Only the top and bottom of the mold are used to fix the copper tube and the water jacket with flanges to prevent deformation of the top and bottom. The middle of the copper tube and the water jacket cannot be combined. The same type of mold is fixed w...
