Problems solved by technology

For example: (1) The slit adopts an up and down straight-through structure, which destroys the integrity of the crystallizer, reduces the overall strength of the crystallizer, and brings unstable factors to industrial production
(2) Due to the existence of slits, each metal sheet layer is independent of each other, resulting in complex cooling water circuit system and difficult design
(3) The distribution of the magnetic field in the mold is not uniform, which directly affects the improvement of the quality of the slab
However, the crystallizer of this design still fails to completely solve the problems of greatly increasing the magnetic permeability and homogenizing the magnetic field, and must overcome the difficulties in material selection and preparation process
The above-mentioned crystallizers are currently in the development and research stage, and none of them have been applied to actual industrial production.

Abstract

A water cooled electromagnetic crystallizer for conticasting is composed of upper and lower flanges, coil, sleeve pipe of crystallizer, cooling water jacket, cooling water tube, connection part and lifting gear. It features that the upper part of said sleeve pipe has local slit structure, the cooling water tube is arranged in split body and a water seam structure is formed between the lower part of said sleeve pipe and cooling water jacket.

Description

technical field [0001] The invention relates to a metallurgical continuous casting crystallizer, in particular to a water-slit-split body water-cooled soft-contact electromagnetic continuous casting crystallizer. Background technique [0002] At present, the electromagnetic casting process of aluminum and copper has become more and more mature. Compared with the traditional direct casting method, the surface quality of the billet has been significantly improved. Due to the high density of steel, the required electromagnetic thrust is large; the electrical conductivity is small, and the electromagnetic thrust produced is small; the thermal conductivity is low, the melting point is high, and the pulling speed is fast, which is not conducive to the formation of the billet shell, so it is difficult for steel to completely realize the moldless electromagnetic connection. cast. Inspired by the electromagnetic casting technology of aluminum and the cold crucible technology, the Fr...
