Square blank crystallizer mechanism for magnesium alloy vertical continuous casting

Abstract

A square billet crystallizer mechanism for vertical continuous casting of magnesium alloy, which belongs to the metallurgical field of metal materials, comprises a crystallizer main body, a frame and a water inlet. The square billet crystallizer is a cuboid shape, a coaxial cuboid hollow body with four round transition corners is processed inside the crystallizer, and a metal plating coat is plated inside the crystallizer. An O-shaped water channel consisting of horizontal water channels and vertical channels mutually intersecting and communicated with each other is processed on four walls inthe crystallizer, and secondary water outlets distributed uniformly and having a diameter gradually decreasing from the middle section to both sides is processed to keep communication with the lower water channels. The included angles between axis lines of all of the water outlets and the axis line of the crystallizer are identical to each other. The square billet crystallizer mechanism manufactured by low-cost common casting method has the advantages of simple structure, uniform cast billet cooling, high production efficiency, high quality of the cast billet and wide application, and is applicable for continuous casting of different materials such as steel, aluminum alloy, magnesium alloy, etc.

Description

technical field [0001] The invention relates to equipment in the technical field of alloys, in particular to a billet crystallizer mechanism for vertical continuous casting of magnesium alloys. Background technique [0002] Continuous casting has the characteristics of improving alloy properties, reducing alloy preparation costs, and high production efficiency. However, the high preparation cost of magnesium alloys is a factor that limits the industrial application of magnesium alloys. Therefore, continuous casting of magnesium alloys is becoming a hot spot in the field of magnesium alloy research. The crystallizer is called the heart of continuous casting equipment and is the most important factor determining the quality of continuous casting slab. Common crystallizers are divided into round and square. The relative advantage of circular mold and square mold is that both primary cooling and secondary cooling can achieve symmetrical and uniform cooling, so crack defects in ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the deficiencies of the prior art, and provides a billet crystallizer mechanism for vertical continuous casting of magnesium alloys, which solves the problem of rapid cooling of the four corners of the magnesium alloy continuous casting billet crystallizer in the prior art and other problems. The parts are cooled slowly, resulting in uneven cooling, and the crystallizer has the disadvantages of complex structure and high cost
