Generalized and systematized materials on the construction, technology and thermal operation of continuous casting machines of workpieces (MNLZ). The results of experimental and computational-theoretical studies are presented, recommendations for improving the thermal work of the MNLZ, the basic principles and methods of heat engineering calculations, including the use of computers. The issues of continuous bottling related to the thermal operation of the main technological units, the crystallizer and the secondary cooling system are covered. For students studying in the specialty "Metallurgy of ferrous metals" .
