DEVELOPED AND APPLIED OF THE HEAT-TRANSFER SIMULATION INGOT CRISTALLIZATION AND HEATING
A mathematical model of the thermal state of the ingots in the crystallization process, the essence of which is to replace the space variables of the differential equation of heat conduction new variables, transforming the area of irregular shape to a single rectangle. With the developed model conducted studies of the dynamics change of temperature fields in large ingots using different modes of transport and heating. Based on these data, a new power-saving mode of transportation and rapid heating of large ingots. Production experiments proved that the use of a new mode of transport and heating of large ingots does not adversely affect the quality of the internal structure of castings. Macrostructure of ingots subjected to rapid heating and transportation, meets the requirements of high-quality steels and chemical heterogeneity of segregating the main elements is different from ingots heated by traditional technology.
