Effect of Ultrasonic Inoculation Treatment on Distribution of Sulphur in Fe-S Alloy

Abstract

Influence of ultrasonic inoculation treatment on distribution of sulphur in Fe-S alloy was mainly studied. Results showed that Ultrasonic treatment could reduce the segregation degree of sulfur in Fe-S alloy and make the distribution more uniform. When the ultrasonic treatment time was 60s, sulfur segregation was in the lowest of 0.3799, and homogeneity was in the maximum of 0.5470.While treated with ultrasonic power of 150W, sulfur segregation was 0.5068, and sulfur segregation was improved, but homogeneity of sulfur decreased to 0.3411, overall homogeneity distribution of sulfur decreased.
