Example Embodiment

[0025] Such as figure 1 As shown, the production process of the present invention includes melting and heat preservation treatment of aluminum and aluminum alloys, melt casting, CASTEX molding, wire cooling and wire take-up. The specific production steps of the present invention are as follows:

[0026] 1) Transfer the aluminum or aluminum alloy ingots to the preheating box to preheat to 240℃~260℃;

[0027] 2) Put the ingot into the heating furnace of the automatic feeding device and heat it to 660°C~720°C. The heating furnace is filled with protective gas during the heating process of the heating furnace to prevent the aluminum and aluminum alloy melts from being polluted;

[0028] 3) Liquid aluminum or aluminum alloy flows into the pouring port of the forming host through the liquid injection pipe of the automatic feeding device;

[0029] 4) DZJ-460 type forming main machine uses liquid aluminum or aluminum alloy to make wire rod. The forced circulation water cooling system is used...

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. [0003] For the production process of aluminum and aluminum alloy wire blanks, generally only products with specifications of ∮8~∮16mm can be produc...
