Abstract
A method for smelting of steel in the basic open-hearth furnace comprises the charging of metal scrap, limestone, return converter slag and others lime-containing materials, oxidizers, melting and finishing. Briquettes of lime fractions to are used during of finishing and (or) charging, at that maximal size of briquette is 0.020- from depth of furnace bath to lever of basic baffles. The consumption of briquettes does not exceed 80 % from sum of all slag-formation materials, which are introduced into furnace in suitable melting period.
