Summary
Subject is read with the purpose to understand the theoretical principles of
steelmaking, the steelmaking technology in particular aggregates, the steel
deoxidization and its treatment by secondary metallurgy, processes taking place during the casting, solidification and crystallization of the steel by the steel ingot casting, and also by the continuous casting machine.
