Originální abstrakt

An original three-dimensional numerical model (the first of the two) of a concasting temperature field had been used. This model is able to simulate the temperature field of a concasting machine (CCM) as a whole, or any of its parts. Simultaneously, together with the numerical computation, the experimental research and measuring have to take place not only to be confronted with the numerical model, but also to make it more accurate in the course of the process. The second original numerical model of dendritic segregation of elements. In order to apply this model, it is necessary to analyze the heterogeneity of samples of the constituent elements and impurities in characteristic places of the solidifying slab. The samples are taken from places which provide information on the distribution of elements under both standard and extreme conditions for solidification, where the mean solidification (crystallization) rate is known for points between the solidus and liquidus curves. Using this method it is possible to forecast the occurrence of the critical points of a blank from the viewpoint of its susceptibility to crack and fissure. Verification of technological inpacts of optimization resulting from both models is made at real industrial CCM. Both models can be used also for continuous casting of billets.
