ABSTRACT

A method is proposed for calculating the basic parameters of a gas jet (its mean mass temperature and power) at a certain distance from the nozzle when slag melt is sprayed onto the converter’s refractory lining. On the basis of a mathematical model, the flow parameters of a complex supersonic jet are calculated, in conditions where not only gas but slag particles are injected into the working volume of a 350-t converter. The mean mass temperature and velocity are determined over the length of the gas jet. The influence of the added slag mass on the mass of added gas and on the gas jet’s temperature and speed is established, with variation in the nitrogen flow rate through the nozzle and the relative temperature in the converter’s working volume. Analysis of numerical results shows that slag injection significantly changes the interaction between the supersonic jet and the melt. Adding even small quantities of slag markedly slows the jet.
