Mathematical modelling of the pure oxygen blowing process on surface of liquid bath in metallurgical aggregates
Original language description
This contribution describes numerical solution of multiphase flowing in metallurgical aggregate for steelmaking with help of software Fluent 6.1.18. Model of furnace contains liquid steel and gaseous phase 1 (clean oxygen) which is blown on surface of liquid bath through the gaseous phase 2 (air) by means of refine nozzles and additional fuel oxygen burner. Three-phases VOF mathematical model was used for solution. Situation when current technology of oxygen blowing on bath surface (application of two refine nozzles) was completed by another auxiliary burner is described in text. Contribution includes information about velocity field distribution inside of furnace in both investigated variants (variant using two refine nozzles and variant with auxiliary burner) and at the same time information about influence (penetration) of oxygen flow on surface (under surface) of liquid bath under condition of oxygen speed variation in outlet cross-section of auxiliary burner.
