摘要

采用近液相线保温的半固态熔体制备技术

制备了C级钢半固态熔体

对该半固态熔体在金属型加压条件下的流变充型能力进行了研究。结果表明

充型压力和模具预热温度越高

半固态低合金钢的流变充型能力越好

其中模具预热温度对低合金钢半固态合金熔体流变充型能力的影响大于充型压力的影响;浇注量的增大将提高低合金钢半固态合金熔体的充型能力;在模具设计过程中

压室的体积和浇道长度的优化设计是关键所在。

Abstract

Near-liquidus techniques was adopted to prepare C-grade steel semi-solid melt

and rheological filling behavior of the semi-solid melt in metal mold under external pressure was investigated.The results indicate that

with the increase of filling pressure and mold preheat temperature

rheological filling behavior of low-alloy steel semi-solid melt is improved increasingly.In addition

the effects of mold preheat temperature is higher than filling pressure on filling behavior.The rheological filling capacity of low-alloy steel semi-solid melt is improved by increasing the pouring volume.Optimization of pressure chamber volume and runner length during design of mold is the key important for desirable filling of semi-solid melt.
