本文研究400kHz高频电磁铸造小截面铸锭的过程。在高频条件下,液态金属成形稳定,液相区内没有强烈的搅拌作用。在感应器作用区内,表面功率密度高。铸出的铸锭表面光滑,铸锭宏观组织为细密的等轴晶。铸锭经机械性能测定表明,硬度低,延伸率高,变形均匀。 This paper studies the process of 400kHz high frequency electromagnetic casting of small section ingot. At high frequencies, liquid metal is stable and there is no strong agitation in the liquid zone. In the sensor area, the surface power density. Cast ingot smooth surface, ingot macro-organization for the fine equiaxed crystal. Measured by mechanical properties of ingot shows that low hardness, high elongation, uniform deformation.
