Abstract

The paper is devoted to the research of application of vortex technologies of the gas jets to increase the efficiency of fire-resistant coatings on the converter lining. Using numerical simulation, the authors considered the aerodynamic pattern in the working space of the unit and the features of the converter slag drop motion when supplying neutral gas through a special lance with the elements of the vortex device. The laws of slag drop motions of different size to the converter lining have been refined, as well as the dependence among the parameters of slag drop movement and the characteristics of the vortex jet has been defined. It has been established that the trajectory of the slag drops, regardless of their size is mainly determined by the degree of twist of the vortex jet. The article also shows the principal possibility of increasing the technological flexibility of the slag skull application process on the lining converter when using vortex gas jets.
