Manufacturing device for light alloy or light metal semi-solid slurry and manufacturing method

Abstract

The invention discloses a manufacturing device for light alloy or light metal semi-solid slurry and a method for manufacturing the semi-solid slurry through the device. The manufacturing device for the light alloy or light metal semi-solid slurry comprises a smelting furnace, a runner, a mechanical stirring device, an inert gas stirring device, a powder spray device and a heating device. The semi-solid slurry manufacturing device reasonable in structure is designed, continuity for manufacturing the semi-solid slurry is good, and products can be cast industrially and continuously in a large scale by applying a semi-solid pressure casting or squeeze casting forming method. According to the manufacturing method for the semi-solid slurry, efficiency for manufacturing the light alloy or light metal semi-solid slurry is high, energy consumption is less, cost is low, and the manufactured semi-solid slurry cannot generate oxide inclusions, and is even in organization and excellent in quality.

Description

technical field [0001] The invention relates to the technical field of preparation of light alloy or light metal semi-solid slurry, in particular to a preparation device and method for light alloy or light metal semi-solid slurry. Background technique [0002] Metal semi-solid forming technology is known as one of the most promising metal material processing technologies in the 21st century. According to different process methods, semi-solid forming technology is divided into two categories: rheological forming and thixoforming. Thixoforming needs to reheat the semi-solid billet, resulting in long process flow and high cost. The semi-solid slurry is directly processed into shape, the process is short, the cost is low, and it has great development potential. [0003] The preparation technology of metal semi-solid slurry is the key technology of metal semi-solid forming. Metal semi-solid pulping methods are mainly divided into stirring method and non-stirring method. The st...

Problems solved by technology

[0005] The disadvantages of the existing preparation device for preparing metal semi-solid slurry by gas stirring are as follows: 1. In the process of semi-solid slurry preparation, metal smelting and semi-solid slurry preparation are carried out in the same equipment, that is, in the same The metal is smelted first in a container, and the semi-solid slurry is directly prepared in the container after the metal is completely smelted. After the preparation of the semi-solid slurry is completed, the semi-solid slurry needs to be removed from the smelting container before proceeding to the next step. Batch metal smelting and preparation of semi-solid slurry, the continuity of semi-solid slurry preparation is poor, and the preparation efficiency is low, which is not conducive to the industrialization, large-scale, and continuous casting of semi-solid die-casting or squeeze-casting forming methods; 2. There is still room for improvement in the quality of the prepared semi-solid slurry
