Crystallizer

Abstract

The invention discloses a crystallizer, belonging to crystallizing devices, which structurally comprises a shell body of the crystallizer, wherein upper water outlets and upper water inlets are arranged on the upper part of the shell body of the crystallizer; lower water outlets and lower water inlets are arranged on the lower part of the shell body of the crystallizer; the upper water inlets and the lower water inlets are respectively two in quantity; the upper water inlets and the lower water inlets are symmetrically arranged; the amount of the upper water outlets is larger than the amount of the lower water outlets; and the lower water outlets and the lower water inlets are arranged in a staggered mode. Compared with the prior art, the crystallizer of the invention has the advantages that the temperature on the surface of cast ingots is reduced so that the tissues of the upper surfaces and the lower surfaces of the cast ingots are uniform; the cooling strength of a graphite plate on the crystallizer is enhanced, and the cooling strength on the lower surface of the crystallizer is reduced so that the upper and the lower cast ingots in the crystallizer can be simultaneously crystallized; the abrasion degree of the graphite plate on the lower surface of the crystallizer is improved to a certain extent; and the service life of the graphite plate is increased, and the like, therefore, the crystallizer has good popularization and application values.

Description

technical field

[0001] The invention relates to a crystallization device, in particular to a crystallizer which can reduce dummy ingot resistance on the lower surface of the crystallizer, improve the quality of the center line of the ingot and the slab, and prolong the service life of the crystallizer. Background technique

[0002] Usually, the crystallizers used in horizontal continuous casting to produce bronze have the same amount of water entering and exiting the upper and lower surfaces, and adopt two-inlet and three-outlet or two-inlet and four-outlet molds, and the number of inlets and outlets on the upper and lower surfaces is symmetrical. However, the traditional crystallizer design does not take into account the difference in the cooling degree of the upper and lower surfaces of the ingot. After dismantling the discarded crystallizer, it can be found that the wear degree of the graphite plates on the upper and lower surfaces of each crystallizer is different, and th...
