Aluminum and aluminum alloy continuous solidification and semi-solid forming process

Abstract

The invention relates to a metal melting, ingot casting and plastic deformation processing process in the production field of aluminum and aluminum alloy pipe, bar, wire and section products. The invention provides a brand new metal solidification and semi-solid forming process for producing aluminum and aluminum alloy pipe, bar, wire and section products. The metal continuous solidification and semi-solid forming process provided by the invention is a new process for metal processing and forming based on the conform technology and combines casting and extrusion. In the forming process, a metal material is subjected to a crystallization solidification and plastic deformation process which is a combination of forced feeding and densification process under high pressure; and the expansion energy provided by external pressure increases the nucleation rate of the material, so that the material tissue is refined and is favorable for improving the electromechanical comprehensive performance of the aluminum and aluminum alloy products.

Description

technical field [0001] The invention relates to metal smelting, ingot casting and plastic deformation processing technology in the production field of aluminum and aluminum alloy "pipes, rods, wires and profile products". Background technique [0002] At present, the production process of domestic and foreign aluminum and aluminum alloy "pipes, rods, wires, and profile products" is complicated, and the investment in equipment is huge; generally, "melting, ingot casting, rolling" or "melting, ingot casting, extrusion" are adopted. , or "continuous casting and rolling", or "smelting, drawing casting" and other processes, not only high energy consumption, low yield, but also poor comprehensive performance (mechanical and electrical properties) of the product, large fluctuations in product performance, and production costs higher.

[0002] At present, the production process of domestic and foreign aluminum and aluminum alloy "pipes, rods, wires, and profile products" is complicated, and the investment in equipment is huge; generally, "melting, ingot casting, rolling" or "melting, ingot casting, extrusion" are adopted. , or "continuous casting and rolling", or "smelting, drawing casting" and other processes, not only high energy consumption, low yield, but also poor comprehensive performance (mechanical and electrical properties) of the product, large fluctuations in product performance, and production costs higher

[0003] For the production process of aluminum and aluminum alloy wire blanks, generally only products with specifications of ∮8~∮16mm can be produced, and it is almost impossible to produce wire blanks with specifications below ∮8mm
