Abstract

Currently there is no systematic approach to the study of the properties and behavior of the steel melt – liquid slags, metals and their alloys. Constant changes in the raw material base, the use along with the traditional and well-established (blast furnace) dynamically developing modern units (EAF), the appearance and use of new ways to influence the melt (electro-magnetic field, electromagnetic hold metal) lead to a significant reduction in the reliability of the usual, the turned years of techniques to improve the efficiency of metallurgical equipment. The rapid development of information technology and computer technology makes it possible to gain new knowledge in the field of comprehensive studies of the properties of metallurgical melts and their behavior in specific circumstances under the given external actions. Scientific interest for authors are the processes occurring in real steel melts. Using the high-performance computing clusters in the simulation of melt structure by molecular dynamics method allows not only getting the latest knowledge on the physical, chemical and mechanical properties, but also to conduct a study of complex multicomponent systems comprising atoms of transition elements, which is a synergy in the melt does not allow to take into account other methods. Smelting (PVA) in the electromagnetic field has a distinct advantage in the absence of contact of molten metal with a refractory lining, eliminate metal contamination, such as oxygen. This is especially important for melting highly reactive and refractory metals. PVA is a progressive universal method for high physical and chemical research needed to improve the metallurgical processes, as well as the means for obtaining metals and alloys required for a number of areas of modern technology. The problems facing steelmakers theorists in the study of high-temperature melts and are the most appropriate methods to address these issues with an emphasis on the use of modern computer technology.
