Crystallizing wheel

Abstract

The invention discloses production equipment for continuous casting and rolling, particularly relates to a crystallizing wheel in continuous casting and rolling equipment, and belongs to the technical field of continuous casting and rolling equipment. The crystallizing wheel comprises a wheel body and a casting groove formed in the outer peripheral wall of the wheel body; a metal filling piece is embedded in the wheel body between the inside wall of the casting groove and the outside wall of the wheel body; and heat transfer coefficients of the metal filling piece are smaller than those of the wheel body. The crystallizing wheel, provided by the invention, is simple and reliable in structure, is convenient to assemble, and overcomes the energy consumption defect that in the prior art, the side wall of the crystallizing wheel is heated by an external heating source; and the problems of cracks and interlayers of a green body, which are caused by the internal cooling strength and the external cooling strength of the casting groove are inconsistent, are avoided through the self structure design of the crystallizing wheel, so that the quality of a product can be improved effectively.

Description

technical field [0001] The invention relates to a continuous casting and rolling production equipment, in particular to a crystallization wheel in the continuous casting and rolling equipment, and belongs to the technical field of continuous casting and rolling equipment. Background technique [0002] The crystal wheel is the key equipment in the aluminum (copper) rod continuous casting and rolling production line. It is generally made of metal material with good thermal conductivity (such as copper or copper alloy), and its outer peripheral wall has casting grooves 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 forming, and with the rotation of the crystallization ...

AI Technical Summary

Problems solved by technology

[0005] In the above two solutions, there are independent heating equipment, which needs to be cooled while heating in another place, which increases the production cost and energy consumption per unit product

In addition, CN204262305U puts forward higher requirements on the manufacturing process of the crystallization wheel, especially under the premise that the material of the crystallization wheel is made of copper or copper alloy, the existing liquid cavity also makes the crystallization wheel withstand high temperature and low temperature periodically Reduced durability under operating conditions
