半固态制浆(坯)工艺研究新进展

Research Progress of Semi-solid Slurrying Technology

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 research progress of semi solid metal pulping technology were reviewed, mainly introducing some new process and new technology in recent years in the semi-solid slurry preparation process, including liquidus casting, tilting plate method, melt spreading and mixing method, low superheat pouring and weak electromagnetic stirring composite pulping technology, melt treatment and reversible electromagnetic stirring composite pulping technology, self-inoculation method. The development trend of semi solid processing technology is further simplifying process, improve production efficiency, reduce processing cost, expand its scope of application.
