Короткий опис(реферат):
The present paper the basic solutions to the problem of obtaining wearfirmness thermite cast iron examined the use of thermite cast iron, the benefits of combining thermite steels with metallotermic methods of getting is showed. The advantages of metallotermic synthesis methods include: autonomy of processes, independence of energy sources, simplicity of equipment, high-performance process and easy transition from experimental research to industrial production. The need to developed the technology of synthesis wearfirmness thermite cast iron, as a result of aluminothermic reactions and establishment of technological features’ of synthesis it all led. At the first phase of the study of chemical composition of the synthesized wearfirmness thermite cast iron
is determined. In continuation of studies microstructure, mechanical and technological tests were performed. Technological features of the synthesis process and the impact of components exothermic reaction were revealed. The result of comprehensive research was the development of fusion technology wearfirmness thermite cast iron “OИ-1”, “OИ-3”, “ИЧХ4Г7Д”, “ИЧХ3ТД”, setting of the charge for the synthesis of the specified cast iron, revealing the microstructure and mechanical properties of thermite steels, the research of technological properties of steel, namely the casting of properties and effects on the structure of individual alloying elements. In addition, the authors have set the limits and boundaries of creep for thermite cast iron and their dependence on temperature.
