The purpose of the study: Analysis of the results of research on energy and resource saving in the foundry industry by increasing the tool life, improving the technology for making molds, cleaning and heat treatment of castings, and using computer-aided design techniques. Methods of research: CALPHAD-method, microanalysis, thermodynamic analysis, standard methods for studying the technological properties of molding mixtures, standard hardness testing methods, regression analysis method. Theoretical and practical results: A thermodynamic description of the binary systems Al-Si, Fe-Si, Al-Fe, and the Al-Si-Fe ternary system has been performed. The conditions for the formation of phases during the crystallization of silumin AK12 in the framework of the thermodynamic model of the system, as well as the conditions for the formation of phases during the crystallization of silumin AK12 in the thermodynamic model of the Al-Si-Fe-Mn system, are analyzed. The choice of the method for producing the compound is substantiated, which provides an increase in the specific strength of Constantine bentonite by 10 ... 23%, depending on the coal content, reducing the mixing time of the mixture to achieve maximum strength. Dependences are obtained that relate the design parameters of the cooling nozzles to the average irrigation density and the uniformity of its distribution over the irrigated surface; the dependences of the heat transfer coefficient on the density of irrigation are established. We have obtained mathematical dependencies which, depending on the different thickness of the metal, allow us to determine the width of the cut, the time for performing this operation, and choose the number of the torch die for these parameters; The features of structure-phase transformations during heating and cooling of gray alloyed iron with a plate-shaped graphite in free-flowing graphite are studied. The formulation of a complex binder (compound) for the formation of a raw material on the basis of a thermally stable Constantin bentonite has been developed. Software has been developed to automate the design of foundry technology using the Cad-System Solidworks. Efficiency of implementation is ensured by the need for research results. Scope: at machine-building enterprises in the production of castings from steels and cast irons.
