A crystallization wheel water jacket cooling system

Abstract

The invention discloses a crystallizing wheel water jacket cooling system and belongs to the technical field of continuous casting equipment cooling. The crystallizing wheel water jacket cooling system comprises a crystallizing wheel and a steel belt. The steel belt is closed, and a casting cavity is formed in the outer edge of the crystallizing wheel. An outer cooling sleeve is arranged on the outer circumferential face of the steel belt, and an inner cooling sleeve is arranged on the inner circumferential face of the crystallizing wheel. Each of the outer cooling sleeve and the inner cooling sleeve comprises a cooling body, and the cooling bodies are in an arc shape matched with the crystallizing wheel. Each of an outer cooling cavity and an inner cooling cavity is divided into at least three circumferential cooling areas in the circumferential direction. Multiple diversion bars arranged in the circumferential direction are arranged on each of the cooling body inner circumferential faces of all circumferential cooling areas of the outer cooling cavity and the cooling body outer circumferential faces of all circumferential cooling areas of the inner cooling cavity, and the multiple diversion bars are distributed in the axial direction of the crystallizing wheel at intervals. Each circumferential cooling area is provided with a water inlet and a water outlet which are located in the two ends of the corresponding diversion bars. Cooling water is spread at all positions of the cooling faces and is sufficiently cooled, weight adjustment of the water volume in each area is achieved, and the casting crystallization process requirements can be better correspondingly met.

Description

technical field [0001] The invention relates to the technical field of continuous casting equipment cooling, in particular to a crystallization wheel water jacket cooling system. Background technique [0002] At present, the crystallizer of the continuous casting machine used to produce copper alloy, aluminum alloy rods and plates for electrical purposes usually includes a steel strip, a steel belt wheel, and a crystallization wheel with annular grooves on the circumference. The steel belt is guided, stretched and tightly attached to the crystallization wheel by multiple steel belt wheels, and the outer edge of the groove of the crystallization wheel is closed by the steel belt to form a cavity extending from the casting port to the casting exit along the circumference of the crystallization wheel. The liquid is injected from the casting port by the pouring pot, and then it is forced to cool and crystallize in the cavity to form a slab, and the formed slab is pulled out from...

Problems solved by technology

[0003] When the pot pours the metal liquid from the crystallization wheel at the casting port, the metal liquid is cooled and formed in the crystallization wheel. The cooling method of the existing plate wheel belt casting machine is spray cooling. Although the water volume can be adjusted in sections, the spray The sprayed cooling water is immediately mixed together, it is difficult to form a clear partition from top to bottom, and it is difficult to realize the requirements for the crystallization process
