GAS DYNAMICS IN THE SMELTING ROOM OF THE MODERN ELECTRIC ARC FURNACE

Abstract

The results from the motion analysis of gas flows which the fuel-burning arrangements give rise inside the operating electric arc furnaces are given in the article and the practical guidelines on the burner's efficient installation diagram were laid down. The controlled round motion of aerodynamic flows inside the smelting room between the wall and electrodes acts to raise of the convective heat transfer exchange with the cold solid batch, and to the reliable even skull layer formation on the water-cooled wall, as well as it promotes the lowering of the dust deposition on the electrodes. The calculation investigation was performed with the using of SolidWorks Flow simulation computational program at the actual boundary conditions. Ill. 4. Ref. 3.
