Abstract

The efficiency of pyrometallurgical plants is determined by their thermal performance. The thermal processes in processing secondary copper-containing materials such as brass scrap are analyzed. The main goal of this research was to take the heat balance and to analyze the most significant heat inputs and outputs. The main heat inputs are from burning gas and exothermic reactions such as the oxidation of zinc and iron. The heat outputs are mouth, lining, and waste-gas losses.

Abstract

Results are presented from a study made of the hydrodynamics of the liquid bath in a TROF converter to find efficient operating parameters for conducting the blow through an unsubmerged lance. The study was performed on a cold physical model. Investigation of the character of development of the blast jet in the bubbling zone made it possible to establish the main forces associated with the mass of the liquid, friction, and buoyancy and to thus determine the hydrodynamics of the liquid bath.

Abstract

Aspects of the hydrodynamics of the bath of a furnace equipped with a submersible lance are studied by cold modeling. The model was made of plexiglass on a 1:12 scale. The main objective was to determine the relationship between the injection rate and the geometric parameters of the lance, as well as the relationship between the geometric parameters of the gas jet and its parameters at the outlet of the lance. This information will be used to design an optimized model of a unit equipped with a submersible lance and develop recommendations on selecting the optimum blast regimes.
