Correlation of Metallized Pellet Decarburization, Heating, and Melting in an Arc Furnace

Abstract

Features are considered for steel smelting in an electric furnace based on analyzing the correlation of metallized pellet decarburization and melting. A method is developed and proposed for controlling the metallized pellet charging regime into and electric furnace bath through hollow electrodes with observation of synchronous performance of melting and loose material (pellets, lime, etc.) charging rate into the hightemperature zone beneath electric arcs. It is established that with supply of pellets into the space below electrodes taking account of intensification of metal decarburization and heating by means of an oxygenfuel burner technical, economic, and production energy indices are improved.
