Description
Summary:This article discusses the aspects of the melting loss in electric steelmaking during continuous feeding of prereduced pellets into the bath of an electric arc furnace via hollow electrodes. It is shown that adjustment of the melting loss and the dust discharge from electric arcs by changing the pellet consumption and accounting for the heat parameters of furnace operation makes it possible to significantly increase the ingot-to-product yield during electric steelmaking.
