Summary

The subject is focused on the theory of thermodynamic and kinematic basics, it solves of mechanisms of metallurgical reactions. The atention is also devoted to the gases behaviour, removal of inclusions, to methods of secondary metalurgy, there are also outlined the priciples of production of clean steel.
