| Research Abstract |
In a horizontal electromagnetic casting (i.e.,HEMC), molten metal which flows out of a nozzle is levitated by imposing direct electric current and direct magnetic flux. Thus, this grocess makes it possible not only to eliminate the surface defects of ingot caused by contacting with wall of mold but also to intend near net shape casting. The additional advantage of this process is favorably applied to the casting of heavy metals at the smaller amount of the expence for investiment than that of the ordinary vertical electromagnetic casting (i.e.,VEMC) already used in the Aluminum industry.
In this work, to clarfy the fundamental process characteristics of HEMC, the experiments casting rod and thin plate of Bi-Sn-Zn alooy were conducted, and the theoretical analysis on the process stability is developed. The HEMC process promises that the products with the desirable shape and the good surface conditions can be obtained under the stable operating conditions determined by the theoretical analysis.
