Light alloy electromagnetic ultrasonic casting and rolling integration device and method

Abstract

The invention discloses a light alloy electromagnetic ultrasonic casting and rolling integration device and method, belonging to the field of metal material preparation technology. According to the invention, the continuous casting technology of a slab is combined with the hot rolling continuous deformation technology, and an electromagnetic/ultrasonic composite field is introduced into a continuous casting crystallizer to provide a light alloy sheet preparation device and method with short flow and high efficiency. The working principle of the electromagnetic ultrasonic casting and rolling integration device is that: the smelted metal liquid is poured into the crystallizer through an immersive spure, and cooled and solidified by the crystallizer to form a blank shell with a certain thickness; the outer part and upper part of the crystallizer are provided with an induction coil and an ultrasonic generator respectively so as to generate an electromagnetic/ultrasonic composite outer field, improve the surface and internal quality of the casting blank and enhance the plastic deformation capability of the casting blank; the high-quality continuous casting slab is directly subjected to hot rolling deformation; and under the effect of multiple rows of rolls at adjustable gaps and close to the crystallizer, the casting blank generates continuous plastic deformation, the thickness is gradually reduced, and the slab of a light alloy is obtained.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, in particular to the continuous casting and rolling technology of light alloy plates and strips. Background technique [0002] Light alloys have low density, high specific strength, good electrical and thermal conductivity, and are renewable. They have become the second largest type of structural materials after steel materials. At present, the production and application of light alloys are mainly cast alloys and deformed alloys. Compared with cast alloys, deformed light alloys can obtain higher strength, better ductility and mechanical properties that meet the requirements of more uses. Develop new deformed light alloys and their forming technology, improve the performance of deformed alloys, and replace steel materials in the fields of mechanical equipment, transportation, aerospace and other fields, to promote energy conservation and emission reduction, and to solve or allev...
