Non-ferrous metal continuous casting-rolling-extrusion integral processing forming device and method

Abstract

The invention discloses a non-ferrous metal continuous casting-rolling-extrusion integral processing forming device and method, belongs to the metallurgical technical field, and relates to the integral and continuous processing forming technology formed by integrating casting, rolling and extrusion processing methods into one. The device and the method can be applied in forming of aluminum alloys, magnesium alloys, zinc alloys, tin alloys, lead alloys and other materials, solve the problems of small plastic deformation and coarse grains in continuous casting and rolling, and also solve the problem that metals with lower plasticity are difficult to form because metal shear deformation is larger in continuous casting and extrusion. The device comprises a machine frame, a casting and extrusion boot, an extrusion forming device, a concave roller, a convex roller, a driving mechanism and a cooling system, and has the structural characteristics that the casting and extrusion boot and the extrusion forming device are respectively and fixedly arranged on the machine frame, the extrusion forming device is provided with an extrusion die, the concave roller and the convex roller driven by the driving mechanism are located between the casting and extrusion boot and the extrusion die, the concave roller is positioned at the upper side, the convex roller is positioned at the lower side, and the center connecting line is vertical to a horizontal surface.

Description

technical field [0001] The invention relates to non-ferrous metal continuous casting, rolling and extrusion forming technology and device. The invention integrates casting, rolling and extrusion processing methods to form an integrated and continuous processing and forming technology. It can be applied to the forming of aluminum alloy, magnesium alloy, zinc alloy, tin alloy, lead alloy and other materials. Background technique [0002] The existing continuous casting and rolling technology is to send the liquid metal between the two rolls of the rolling mill through the diversion groove, and cast and roll out the plate and strip products; at this time, the rolled products have little deformation due to the limitation of the continuous casting and rolling technology , coarse grain, poor plasticity, can only be used as a semi-finished product of thin rolling. In addition, at present, continuous casting and rolling can only cast and roll slabs, and cannot cast and roll tubes, ...

AI Technical Summary

Problems solved by technology

It not only solves the problem of small plastic deformation and coarse grains in continuous casting and rolling, but also solves the problem of large shear deformation of metal during continuous casting and extrusion, which makes it difficult to form metals with low plasticity
