以及高效铝熔体处理的理论及其关键技术

并进一步探讨了铝熔体高效净化、富Fe杂质相变质和晶粒细化处理技术的效果及其相互关系。提出"净化是铝熔体处理的关键

是细化和变质的基础"的熔体处理原则;据此研究获得了铝熔体高效综合处理技术

并在高性能罐用铝材等多种材料的制备中得到实际应用

显著地提高了铝材的冶金质量

从而使其力学性能、尤其是塑性得到了较大幅度的提高

有利于其后续的轧制加工及产品的最终性能的提高。该技术对其他高性能铝材也具有直接的应用价值。

Abstract

Important role of melt-treatment for liquid Al and theory on high efficient melt-treatment as well as key techniques were expounded.Furthermore

effects of melt-treatment techniques such as high efficient purification

modification of impurity-phase containing Fe-rich and grain refinement on the Al melt quality and interrelation among these treatment techniques were approached.The principle of melt-treatment that purification is a key process of Al melt treatment and base of refinement and modification is presented.Based on the principle

high efficient melt-treatment techniques were developed to be applied to the preparation of Al sheets for the can with high performance

which can significantly improve the mechanical properties of the Al sheets

especially the ductility

due to the great improvement of melting quality of the Al sheets

helpful for the sequent rolling and performance of the finished product.
