7. Thermal work of linings – solving of the temperature field of lining in a time- steady and unsteady state, one-sided heating, heating throughout the volume, continuous and cyclic heating, 1 and 2 Fourier's law, initial and surface conditions.
8. Solution unidirectional non-stationary temperature field in an infinite plate and in an infinite cylinder for various marginal conditions (q = const.; tarea = const; tsurf = const.; tsurf = f (time); tarea = f (time), etc.).
9. Corrosion effect on the lining and actions to its prevent - study of the interaction between slag and refractory materials (Application of ternary diagrams), a lining cooling.
10. Technology of making the linings. Linings of dense shaped material, unshaped building materials, lightweight and fibrous materials. Refractory monolithic linings. Anchoring and hanging of lining.
11. Lining construction of particular metallurgical aggregates (VP, hot blast, pig iron mixer, converter, tandem furnace, EAF, electric induction furnaces, etc.).
12. Lining construction in the secondary metallurgy (ladles, tundish + shielding and immersion tube, equipment vacuum treatment of steel, etc.).
13. Lining construction of furnaces in ceramic, glass industry and energetics (dryer of matters, chamber furnace, tunnel furnaces, shaft and rotary kilns for firing of raw materials, glass melting furnaces).
14. Repair of lining - lining repair technology "cold" and "hot" (shotcreting, slag splashing, slag coating, etc.), ways of increasing the life of a furnaces lining and thermal devices.
Practical part
