Abstract: The USTB(University of Science and Technology Beijing)furnace wall oxygen injection technology have been used for a 50 t EBT arc furnace and a 60 t shaft arc furnace at Nol melting shop at Fushun Steel by cooperation of Fushun Steel and University of Science and Technology Beijing. The application results showed that the tap to tap time re- duced by 4.9~7.2 min with 100% scrap charging and reduced by 9.4～10.9 min with 70% scrap and 30% hot metal charging; the electric power consumption decreased by 17.9~37.2 kWh/t,while oxygen consumption increased by ~4.5 m³/t.The service life of USTB oxygen lance was up to more than 1000 heats to get good economic and technical effect.
