Abstract

The invention belongs to the technical field of horizontal continuous casting of copper alloy, and provides a horizontal continuous casting crystallizer, which comprises a cooler, a graphite die and a fixed frame, wherein the cooler comprises an inner tube and an outer tube; a dentate cooling channel is formed between the inner tube and the outer tube, and the inner wall of the inner tube is in close contact with the outer wall of the graphite die; the graphite die is arranged in the cooler which is arranged in the fixed frame. According to the horizontal continuous casting crystallizer, provided by the invention, one time of water cooling can complete rapid cooling of a casting blank, the horizontal continuous casting crystallizer is suitable for mass production, the average speed of casting reaches 300kg / h, the casting defects such as segregation, shrinkage cavity, shrinkage porosity and the like of the casting blank are overcome, the microstructure is uniform, the performance is stable, the service life of the graphite die is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a horizontal continuous casting device, in particular to a horizontal continuous casting crystallizer. Background technique [0002] Mold is the key part of horizontal continuous casting device, the cooling rate of mold determines the casting speed of horizontal continuous casting device, the cooling and heat exchange mode of mold determines the quality of slab. [0003] The crystallizer used in the prior art is generally a cavity cooling structure composed of a cooling device and a graphite mold arranged in the cooling device to cool the slab. The current horizontal continuous casting process mostly adopts closed casting, and the crystallizer is directly connected to the holding furnace. When casting materials in batches, the crystallizer must withstand the test of high temperature for a long time. However, due to the inappropriate structural design and material selection of the cooling device, secondary water cooling or even...
