Parameters are developed for combined extra-furnace treatment of molten blast-furnace iron using pulsating blowing by inert gas. The new technology provides a marked improvement in operating life of replacement components of metallurgical equipment (molds, pallets, slag pots). The possibility is demonstrated of repeated use of naturally-alloyed pig iron in the form of mold scrap under induction melting...
A melt’s condition before solidification is important for improving low-alloy steel metal product quality. It depends on melting method, form or type of charge materials used, melting temperature and time parameters, mixing intensity during extra-furnace treatment, and other production methods. Improvement of the level of molten steel’s physical properties as a result of some action points to the...
