Invented by PTI, Inc. the patented JetBOxTM supersonic oxygen injection system has proven to be an effective tool in increasing Electric Arc Furnace (EAF) production at the same time reducing conversion costs of the EAF. This effect has been achieved by developing for each individual meltshop a unique, efficient method of chemical energy introduction. As each system installation was optimized, the JetBOxTM system evolved to meet the different demands of each meltshop. The JetBOxTM system has been installed in EAF’s utilizing batch scrap charging, ConSteelTM process, DRI and hot metal operations with equally good results. Since 2001 JetBOxTM systems efficiently and safely operate at over 50 different steel facilities meeting the challenge presented at each individual mill.
