摘要：
Production of high-alloy special steels in the electric arc furnace (EAF) requires the use of several different melting practices - from standard foaming slag operation through recovery heats with no foaming slag, to heats with large amounts of FeCr charged into the furnace after earlier phosphorus removal. To reach target carbon content in steel, decarburization by oxygen lancing or recarburization by carbon injection are required. This paper presents the operational results after the installation of INTECO PTI JetBurner and Annulus Burner injection tools on the EAF at Metal Ravne, a Slovenian special steel producer. The installed tools proved to be very efficient and successfully replaced previously used door lance manipulator.
