Modeling was carried out and calculations were obtained of the temperature indicators of the main components of a laboratory-industrial installation for the production of long flat bimetallic products. The design of the die of the casting unit was improved. The optimal and technologically feasible range of die heating temperatures was determined. It was shown that changes in the design of the die together with its additional heating increase the manufacturability of the bimetallic billet production process with a more favorable heat distribution in the casting unit. The general scheme for continuous production of bimetallic bars has been modernized. Based on mathematical modeling and full-scale experiments using a new design die and its simultaneous heating by an induction source, a technological process for the production of bimetallic bars made of steel and bronze by a continuous casting-induction method has been developed for a ratio of the melt thickness to the billet thickness of 10/3. A study of the liquid-solid phase connection and the formation of a transitional contact layer under conditions of electromagnetic levitation of materials with a sufficiently large difference in melting temperatures, in particular, liquid copper and aluminum with a solid steel substrate, has been conducted. The mechanisms and sequence of the formation of transitional layers have been established. Product Description popup.authors Liudmyla V. Mosentsova Pavel I. Kirchu Oleksandr P.
