Optimization of Calcium Treatment to Improve Cleanliness of Cast Steel

Abstract

The effect of Ca additions on the composition, size, shape, number and distribution of inclusions in cast steel melted in a 1 ton induction furnace was studied. in order to achieve optimal inclusion modification and minimal inclusion content, several heats with different amounts and speeds of Ca wire and CaSi-wire injection in the ladle were performed. in some heats, Ar-stirring was used after Ca-wire injection. Samples collected from the furnace, ladle, and cast product were analyzed for inclusions using an automated Aspex Metals Quality Analyzer. This study summarizes the complex effects of Ca-wire treatment and Ar-stirring on inclusions in steel castings.
