Povshuk V. Nano-reinforced periclase-carbon refractories for converter lining using a complex antioxidant

The object of research is the technological parameters of the production of periclase carbon refractories for lining of different converter zones. The aim of the study is the development of the compositions and technology of periclase carbon refractories for different zones of the converter lining with specified physical and mechanical properties as well as increased resistance against slag and oxidation action. Research methods - thermodynamic, X-ray diffraction, differential-thermal, petrographic, electron microscopic. Physical-mechanical and technical properties were determined according to the State Standard of Ukraine. The processing of experimental data was carried out using mathematical statistics methods. Theoretical and practical results - on the basis of the scientific positions and experimental data obtained the technological processes and compositions of periclase carbon refractories and fluxes have been developed. Novelty - obtaining the nanostrengthened periclase carbonaceous refractories by synthesis of nanosized β-SiC and NiO carbon matrix-base with given structure and providing its maximum structural strength through the use of optimal sol-gel ratio of additives, which modify the phenol-formaldehyde resins, and nickel antioxidant components precursors, have been proved theoretically and experimentally. Degree of implementation - the results of the thesis introduced in the LLC "PA"Ukrspetsohneupor"(c. Zaporizhzhya); in the educational process of the department of technology of ceramics, refractories, glass and enamels NTU "KhPI". Scope of application - the developed technology can be used at the enterprises of refractory industry, and items - at metallurgical enterprises as lining converters materials. The results of research can be recommended for training of specialists in the technology of refractory non-metallic and silicate materials in high schools.
