Inoculation of Al-Si alloys using the electromagnetic stirring method


In this research paper results concerning the inoculation method based on electromagnetic stirring of hypoeutectic aluminum with silicon alloys AlSi2 and AlSi7 grade are presented. The inoculation process used a stirrer supplied by current with a high frequency, generating a rotating electromagnetic field. The efficiency of inoculation was estimated in the results of the metallographic macro- and microscopic research. Moreover, the possibility of using the obtained results in horizontal continuous casting process of Al-Si alloys was presented.
