概述了半固态金属制浆(坯)工艺的研究新进展。半固态加工技术的发展趋势是进一步简化工艺、提高生产效率、降低加工成本、扩大其应用范围。主要介绍了近几年在半固态浆(坯)料制备过程中提出的几种新工艺和新技术。其中有液相线铸造法、倾斜板法、熔体分散混合法、低过热度浇注和弱(行波)电磁搅拌复合制浆技术、熔体处理+双向电磁搅拌复合制浆技术、自孕育铸造法。
The recent progress in research on semi-solid metal pulping (billet) process is summarized. The development trend of semi-solid processing technology is to further simplify the process, improve production efficiency, reduce processing costs and expand its scope of application. Several new techniques and new technologies proposed in the preparation of semi-solid slurry (billet) in recent years are mainly introduced. Including the liquid line casting method, inclined plate method, melt dispersion mixing method, low superheat pouring and weak (traveling wave) electromagnetic stirring composite pulping technology, melt processing + two-way electromagnetic stirring composite pulping technology, self-conceived casting law.
