CONTRIBUTION OF THE CHAIR OF FERROUS METALLURGY TO THE DEVELOPMENT OF THE THEORY AND TECHNIQUE OF HIGH-TEMPERATURE MODELING OF CONVERTER BATH BLOWING

The paper presents the results of developing and improving the
systems and methods of high-temperature hydrogasdynamic and mass transfer modeling of top and combined blowing in a converter bath. The role of the Chair “Ferrous Metallurgy” of Siberian State Industrial University in the development of theoretical aspects of blowing the metal melt in converter with gas jets has been shown. Owing to the use of converters with viewing windows, the usage of special techniques of visualization of the reaction zone and a video, it has been able to observe and record the picture of physical phenomena on the surface of the blown bath converter with the video camera. The developed technique of a converter transparent wall has allowed obtaining reliable information on the condition and movement of slag-metal interface at various ways of blowing and formation mechanism of emissions. The developed and proved main propositions of the methodology of high-temperature simulation of different options of converter bath blowing with a proposal of the dynamic similarity criteria allow with high confidence to transfer
the data obtained from the model for the industrial design. Practical options of the approach have been proposed to study hydrogasdynamic and heat-and-mass transfer processes occurring in the main reaction zones of a converter workspace at the top and combined blowing.
