Oxygen injection and consumption of a lance at a basic oxygen furnace

Basic oxygen furnaces use significant amounts of oxygen (O2) to convert pig iron to steel by decarburization. A water-cooled top lance, with a single oxygen line, is used to inject O2 into the liquid metal. The flow rate, pressure, and temperature of the 2 must be controlled and adjusted correctly. While the flow of oxygen can be measured precisely with an ultrasonic gas flow meter, pressure sensors and thermo elements deliver precise and reliable measured values with short response times. Specific consumption parameters can be calculated from this combination.
