With the use of numerical modeling an investigation of the process of the jet guniting of the walls of a steel-making converter is considered. By the jet guniting is meant the process of making an additional protective refractory coating on the basic lining of the walls of the steel-making converter with the aid of a system of two-phase jets transporting a softened refractory material (magnesite) to the converter wall. The results of numerical modeling agree quite satisfactorily with the experimental results in terms that the highest penetration rate of particles takes place in the region of high temperatures near the nozzle block axis into which the particles migrate under the action of turbulent fluctuations of the carrying gas flow.
