Summary

Subject is read with the purpose of understanding of basic theoretical and practical knowledge of methods of secondary metallurgy during treatment of liquid steel. Students will be also introduced to basic findings from the field of steel casting, namely during classic method into ingots and especially during progressive method by the help of continuous casting.
