【摘要】 金属熔体均细处理技术(或称外场处理技术)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,本文提出了评价外场处理技术的三个原则: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"。更多还原

【Abstract】 Melt Fine Treatment(or External Field Treatment) is one of the important categories of metal-melt treatment technology.It applies for semi solid or liquidus rheoforming to most of the casting occasions.The aim is achieving entire homogenization and refinement of the casting structures.Based on cost performance,here presents three principles for evaluation of the external field technologies:simple process,uniform refinement and low defect.Through objectively evaluate of the existing external field technologies,this paper suggests that a novel Rotary Shearing Dispersing technology(RSD) which similar to soymilk-maker is feasible in generous commercial applications.更多还原
