Abstract: Refractory lining damage fixing is a complicated task, because of high temperature usage of installation and various characters of possible lining damages. So, only damages, which have connections with working surface of the lining, could be fixed directly. Such dangerous damages as metal penetration between working and control layer of the installation of thin inner cracks are invisible for visual methods of control, laser scanning of the surface for example. But all these damages have some temperature effects on the outer surface of the metal casing of the installation. This temperature effect can be fixed with up-to-date measurement equipment and the obtained data is enough for fixing and characterization of the damage. A Complex of mathematics and physics methods (such as FEM, Relaxation, heat likeness and so on) is needed for transformation of the outer temperature field of installation into the 3-dimentional damage map of the lining. This Complex was successfully applied for heat transfer modeling and damage fixing for such equipment as casting ladle, RH-degasser and VD-VOD degasser.
Brief Biography of the Speaker:Andrew V. Zabolotsky was born in St. Petersburg, Russia in 1975. He had graduated from St. Petersburg State Institute of Technology (Technical University), department of High-Temperature Materials in 1998. He had defended a thesis about technology of silicon nitride ceramics and received PhD degree in technical sciences in 2002. After graduating he worked at JSK “Sigma-T” (2000-2002) – a producer of high-temperature testing equipment for ceramics and refractory materials as a head of heat insulation department. Between 2002 and 2004 he was a technologist at laboratory of “Refractory materials ltd.”, a company which produced refractory concrete for iron and steel industry. At the present time he is an engineer-technologist of “Magnezit Group ltd.” – one of the main producers of periclasse-carbon refractory materials in Russia and Europe. He had prepared about 20 papers for different journals in Russia and other countries (mostly between 2009 and 2011). He was a participant of several international conferences (for example IAS Conference in 2009 at Buenos Aires, Argentina, WSEAS Conference in Puerto de la Cruze, Spain in 2010). He is WSEAS (since 2010) and AIST (Association of Iron and Steel Technology) member since 2011. At the present time he is working with problems of heat exchange in refractory linings of metallurgical installations and using of mathematics methods for emergency forecasting in metallurgy.
