Optimization of Calcium Treatment to Improve Cleanliness of Cast Steel
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.
