Description

technical field [0001] The invention relates to an integrated equipment for semi-solid slurry preparation and molding, which belongs to the technical field of material processing equipment. Background technique [0002] Semi-solid molding technology, referred to as SSM, has received extensive attention and in-depth research since it was pioneered by Professor M.C.Flemings of the Massachusetts Institute of Technology in the early 1970s. Compared with traditional casting, semi-solid molding technology has a certain volume fraction of solid phase in its liquid phase, which has small latent heat of crystallization and small solidification shrinkage. Therefore, the formed parts have compact structure, high mechanical properties, high dimensional accuracy, can realize near-final molding, have little thermal impact on the mold, and can improve the service life of the mold. Compared with traditional forging, it contains a certain amount of liquid phase, has small deformation resist...

AI Technical Summary

Problems solved by technology

The preparation process of semi-solid alloys includes smelting, pulping and forming. The molten metal after smelting needs to be nucleated and then manually transferred to the forming equipment. Threat, can not meet the production requirements of the industry

For the nucleation process, commonly used methods include mechanical stirring method, electromagnetic stirring method and inclined plate cooling method, etc., but there are obvious deficiencies in all of them.

For example, the mechanical stirring and electromagnetic stirring equipment are huge, the investment is high, and the energy consumption is large, resulting in high preparation costs; and the inclined plate is easy to stick to the alloy melt, which needs to be cleaned continuously, which wastes the alloy
