Modeling and calculation of the temperature fields in two-layer articles

A mathematical model and algorithm for calculation of the temperature fields for two-layer articles are developed. Using the new algorithm a program is created and numerical calculations of the temperature fields that develop in a two-layer article (nonswirl nozzle) in the course of preparation of the pony ladle of a continuous-casting machine for service and in its operating regime are performed. With the use of the program and computer software (in light of experimental results) it becomes possible to perform calculations and predict the sintering mode of ceramic refractory materials as well as optimize the temperature and time heat-treatment diagrams of one-and two-layer articles.
