Cooling structure with baffling function for inner loop surface of continuous casting crystallizer

Abstract

The invention discloses a cooling structure with a baffling function for an inner loop surface of a continuous casting crystallizer. The cooling structure comprises a crystallizing wheel body assembled between two turntables; a transverse plate, positioned on the annular inner side of the crystallizing wheel body on the circumference, is arranged between the two turntables; a main cavity through which a cooling liquid flows is defined by the crystallizing wheel body, the turntables and the transverse plate; annular cavities, communicated with the main cavity, are formed between assembled surfaces of the crystallizing wheel body and the turntables; inlets are formed in the transverse plate; outlets are formed in the turntables at the positions of the annular cavities; baffle plates are arranged on the inner circumference of the main cavity; and a baffle passage, extending from the middle to the two sides in the main cavity, is formed in the width direction of the main cavity between two adjacent baffle plates. The cooling structure is skillful in design, and simple and reliable in structure, and compared with a conventional cavity type cooling scheme, the cooling efficiency of the inner loop surface of the continuous casting crystallizer can be effectively improved, and the stability of the cooling process is beneficial for improvement.

Description

technical field [0001] The invention relates to continuous casting and rolling production equipment, in particular to a cooling structure with baffles on the inner ring surface of a continuous casting crystallizer, belonging to the technical field of continuous casting and rolling equipment. Background technique [0002] The crystallizer is the key equipment in the aluminum (copper) rod continuous casting and rolling production line. The crystallization wheel is generally made of a metal material with good thermal conductivity (such as copper or copper alloy), and its outer peripheral wall has a casting groove set around the circumference. . During the working process of the production line, the steel belt pulley pulls the steel belt and the casting groove of the crystallization wheel fits to form a mold cavity. After the molten metal enters the mold cavity from the casting port on one side, it is cooled, crystallized and solidified in the mold cavity. The process of formin...

Problems solved by technology

[0006] However, due to the annular structure of the crystallization wheel and the rotating production process, the distribution of the cooling liquid and the full contact of the cooling liquid on the cooling heat transfer surface have not been fully resolved in the design of the cooling scheme of the existing cooling chamber, especially In CN204321127U, the design of the coolant inlet and coolant outlet located on
