Split type crystallizer

Abstract

The invention discloses a split type crystallizer. The split type crystallizer comprises two large surface walls, two small surface walls and a plurality of graphite flakes, wherein the larger surface walls and the small surface walls jointly form a crystal passage in a surrounding mode, and the graphite flakes are shaped like strips and vertically arranged on the inner wall of the crystal passage. According to the split type crystallizer, the graphite flakes are arranged on the inner wall of the crystal passage, and therefore the high temperature resistance is improved compared with a crystal passage with chrome plated on the inner wall, and the service life of the split type crystallizer is prolonged. In addition, the structure spliced by the multiple strip-shaped graphite flakes is adopted, damaged graphite flakes can be replaced conveniently, and therefore the maintenance cost of the split type crystallizer is lowered, and only the partial damaged graphite flakes are replaced rather than all the graphite flakes or even the whole crystallizer.

Description

technical field [0001] The invention relates to a split crystallizer, which belongs to the technical field of metal smelting and casting. Background technique [0002] The crystallizer used in metal casting, its main material is copper and other good heat-conducting metals, by setting cooling channels in the mold, the coolant flowing through the cooling channels absorbs and transfers the heat of molten metal and metal castings; but in order to ensure For the strength of the casting, the mold needs to have high mechanical rigidity. The surface of the crystallization channel of the integral crystallizer in the prior art is chrome-plated, and its high temperature resistance still cannot fully meet the needs of existing metal smelting and production, thus resulting in a short service life of the crystallizer; and the crystallization channel of the integral crystallizer Once damage occurs, it is difficult to repair the inner wall of the crystallization channel, so the entire cry...

AI Technical Summary

Problems solved by technology

The surface of the crystallization channel of the integral crystallizer in the prior art is chrome-plated, and its high temperature resistance still cannot fully meet the needs of the existing metal smelting production, thus resulting in a short service life of the crystallizer; and the crystallization channel of the integral crystallizer Once damage occurs, it is difficult to repair the inner wall of the crystallization channel, so the entire crystallization needs to be replaced, resulting in high maintenance costs for the crystallizer

In addition, the existing mold cooling channel is usually a blind hole structure, which is difficult to process, resulting in low mold production efficiency
