Development of Extra-Furnace Treatment Technology for Blast-Furnace Iron in Order to Manufacture Replacement Metallurgical Equipment with Improved Operating Life

  • Published:
Metallurgist Aims and scope

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 conditions for heat-resistant components.
