Embodiment

[0054] Weigh 1000 mesh 5kg metal pure magnesium powder, and weigh 1000 mesh 0.3kg metal pure zinc powder at the same time, put the above raw material powders into different metal powder storages for standby.

[0055] The dynamic flow rate control valve is controlled by the control system, so that the powder flow rates in the two metal powder reservoirs are different, and then the Mg\Zn metal mixed powder with Zn content varying from 0% to 6% is obtained.

[0056] According to the flow rate of the metal powder inlet, adjust the screw speed:

[0057] r=(v e D. e 2 cosΦ) / {(D B 2 -D S 2 )·B}

[0058] In this example, the feeding speed is v e =1×10 5 mm / min; barrel inner diameter is D B =150mm, screw root diameter is D S =50mm; the diameter of the feed port is D e =20mm; the axial distance between the screw edges is B=50mm; the helix angle of the screw is Φ=37°, so the screw speed is calculated to be r=32 revolutions / min.

[0059] According to different raw materials a...

Abstract

The invention belongs to the field of metal processing preparation, and in particular, relates to a method for high-throughput preparation of multi-component gradient metal materials for multi-component alloy tubes, rods, sectional materials and other long materials with continuous gradient distribution of chemical components in the length direction. The device comprises a powder flow velocity on-line regulating system, a rotary feeding system, a heating system, a heat preservation system, a motor drive system, a blank forming system and a control system. By adopting the technical scheme, the device has the advantages of simple structure, convenient use and easy control; the device achieves preparation of high-throughput preparation of the multi-component gradient metal materials through controlling of molten metal components and a continuous casting process, shortens the time course of the materials in composition design, melting, performance preparation and application preparation, reduces the metallurgical energy consumption of multi-furnace smelting of the alloys, reduces development costs, and improves the preparation quality and efficiency of the new metal gradient materials.

Description

technical field [0001] The invention belongs to the field of metal preparation and processing, and in particular relates to a forming device for long materials such as multi-component alloy tubes, rods, profiles, etc., whose chemical composition changes continuously along the length direction, and can realize high-throughput preparation of multi-component gradient metal materials. Background technique [0002] Metals and metal matrix composites have been the most demanded and widely used materials for military and civilian use due to their high strength, high toughness, easy formability, and fatigue resistance. However, the R&D and application of metal materials often rely on traditional material methods such as scientific intuition, human experience, and trial-and-error methods. Long cycle times and high costs have become bottlenecks restricting economic and social development and technological progress. At present, the key issues restricting light metals and light metal ma...
