The content of the leading elements in the technical composition of high-ash coals on the territory of Kazakhstan makes it possible to obtain a complex alloy. In accordance with this, a comprehensive study of the possibilities of obtaining an Aluminium-chromium-silicon alloy, which can be a complex deoxidizer and reducing agent, is among the topical issues. The article presents the results of a study of the thermodynamic-diagram analysis of the Cr-Si-Al-C multicomponent system, where, on the basis of thermodynamic data, the boundary ternary systems of the basic four-component Cr-Si-Al-C system are constructed. As a result, the components of the condensed phases of a multicomponent system were determined. Descriptions are given for each of the defined phases, with the help of which it is possible to create an accurate model of the general system of compositions of chromium-containing melts with the calculation of their normative phase compositions. Triangles of the Cr-Si-Al-C system have been established, modulating the compositions of the resulting compositions of metal products during the smelting of the aluminosilicochrome alloy using high-ash coals. As a result of modeling, the main components of the phase of three-component systems Аl-Si-С, Аl-Cr-Si, were revealed. Volumes and color integrals indicating condensed and gaseous phases are determined. The technology of obtaining silicon-aluminum alloys is based on the reduction of oxides from the ash of high-ash coal with its own carbon in ore-thermal furnaces.
