Abstract

The invention provides a device for preparing a metal semi-solid material. The device comprises a fixing device, a moving device, a mechanical stirring device and a dumping device, wherein the fixing device is used for installing the moving device, the mechanical stirring device and the dumping device, the moving device is used for storing and moving a metal melt, the mechanical stirring device is used for stirring the metal melt, the dumping device is used for dumping the metal melt, and the fixing device comprises a stainless steel base support, a stainless steel base top plate and a base bottom plate which are welded into a whole. According to the device and method, a mechanical crushing principle is used, crystal nucleuses of the metal melt are crushed through a balance body, heterogeneous nucleation is promoted, grains are refined, the grains in the metal melt are evenly distributed through mechanical stirring of the rotating balance body and disturbance of a temperature field, and the pure metal semi-solid material with the fine grains evenly distributed is obtained.

Description

technical field [0001] The invention relates to the field of processing semi-solid metal materials, in particular to a device and method for preparing metal semi-solid materials. Background technique [0002] Semi-solid metal processing is a hot spot in metal processing technology research in recent years. Semi-solid technology has a series of characteristics, such as high precision and good quality of formed parts, and can be in line with net near forming or net final forming. Compared with ordinary processing methods, semi-solid forming has a wider range of applications, and all alloys with solid-liquid two-phase regions can achieve semi-solid forming. And it can be applied to a variety of forming processes, such as casting, extrusion, forging and welding. The semi-solid filling is stable, without turbulence and splashing, the processing temperature is low, and the solidification shrinkage is small, so the dimensional accuracy of the casting is high, and the size of the ...
