摘要

This report describes research of thermal processes in primary cooling area in terms of assessment of temperatureprofiles and determination of thermal flows of the mould. Even formation of casting crust in mould dependson its thermal work, related to distribution of temperature along the height of individual mould walls,which affects operation of the whole continuous casting machine (CCM) in fundamental way. Ideal temperatureprofile along the height of the mould assures even removal of heat from a blank and it is an essential prerequisiteof high quality production. A separate part has been dedicated to ways of preventing breakouts withthe use of simulation of kinetics of the mould temperature field. Some of the achieved results are shown onparticular examples.
