金属熔体外场处理技术是金属熔体处理技术的重要类别之一,它应用于金属半固态或低温液态流变成形等各种铸造场合,目的是实现凝固组织的整体均匀化和细化。基于性价比,提出了评价外场处理技术的3个原则:工艺简单原则、均匀细化原则和减少缺陷原则。结合对现有外场处理技术的客观评价,引荐了一种类似豆浆机原理的“金属熔体切割破散处理技术”。 Metal melt field treatment technology is one of the important categories of metal melt processing technology, it is used in metal semi-solid or low temperature liquid rheo-forming and other casting occasions, the purpose is to achieve uniform solidification organization and refinement. Based on the cost performance, three principles for evaluating the field processing technology are proposed: the simple process principle, the uniform thinning principle and the principle of reducing defects. In combination with the objective evaluation of the existing field treatment technology, a similar “smelting metal cutting”
