Research objective: to analyze the impact of different factors on the change in the structure and crystallization, thermal and chemical-thermal treatment of steel and cast iron. Methods: mathematical, physical and structural methods of research technology for castings. It developed methods include: research methodology transformations during continuous cooling of steel in the bulk graphite, in-mold technique to study the process of modifying and methodology of the study the influence of chemical heat treatment of steels and cast irons on the formation of surface diffusion layers; technique to study the processes of melting and crystallization of alloys technique to study the influence of computer-aided design foundry equipment for casting quality and methodology of studies of the influence of various factors on the quality of cohesion bimetallic castings; technique to study the influence of isothermal annealing and isothermal hardening on structural transformations and mechanical properties of tool steels. Theoretical and practical results. The regularities of the structural and phase changes during crystallization, thermal and chemical-heat treatment of steels and cast irons. Proposed and investigated for effective technological options in-mold melt processing. The mathematical and graphical dependency characterizing the effect of saturating the mixture on the formation of surface layers in a multi-component chemical and thermal treatment of carbon steels. The dependence between the structure of the surface layer and the nature of the formation of cracks in the surface layers after chemical and thermal hardening heat treatment of steels. The possibility of obtaining bimetallic castings by melting without pre-processing of the workpiece surface, and the optimal ratio of wall thickness, so that the resulting high quality bi-metal adhesion. The design of the spray nozzle assembly of industrial cooling systems. Novelty. Is to establish the relationships between technological factors and structural and phase transformations during crystallization, thermal and chemical-heat treatment of steels and cast irons. The obtained dependences allow to develop new and improve existing processes molding, thermal and chemical-thermal treatment. The effectiveness of the implementation is provided by the need for research results. The area of application. Machine-building enterprises in the production of castings made of steel and cast iron.
