Light alloy magnetic ultrasonic casting and rolling integrated device and method

Abstract

The invention discloses a light alloy magnetic ultrasonic casting and rolling integrated device and method. The device comprises a runner, a crystallizer, an ultrasonic generator, an induction coil, aroller and a straightening channel. A generating device of the ultrasonic generator extends into the crystallizer; the induction coil is arranged on the outer wall of an inner groove of the crystallizer; inner and outer cooling rooms are arranged on the outer side of the induction coil; the cooling rooms are of water-cooling structures with double channels; a cooling water inlet is formed in theupper end of the outer cooling room and a cooling water outlet is formed in the lower end; the inner cooling room is of an air cooling structure; an air inlet is formed in the upper end of the inner cooling room while an air outlet is formed in the lower end; a film layer, through which only wind can enter and water cannot be discharged, is arranged between the inner cooling room and the outer cooling room; the straightening channel is arranged at the outlet of the crystallizer, a discharge channel is arranged below the straightening channel and the roller is arranged out of the discharge channel for rolling a finished product into a panel. By combined cooling of air cooling and water cooling, the crystallizing speed of the light alloy crystals is fast, and the production cost is low.

Description

technical field [0001] The invention relates to a powder superalloy rod, in particular to a light alloy magnetic ultrasonic casting-rolling integrated device and method. 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. However, wrought light alloys, especially magnesium alloys, have low strength at room temperature and high temperature, poor plastic deformation ability, and high production costs of plates and strips, which limit their application range and product form as high-performance structural materials. The manufacturing proce...

AI Technical Summary

Problems solved by technology

This process has long flow, large energy consumption, high metal loss, and high cost. Especially when it is used to produce materials with poor plastic deformation ability such as magnesium alloy, the slab is difficult to plastically process at room temperature, and the yield is low. For 1.0 The finished product rate of mm thick magnesium alloy plate is only about 20%.
