Abstract
A method of controlling independently of each other the stirring strength of a jet of oxygen gas and the flow rate of the oxygen gas to be blown onto a molten metal bath in a top-blowing oxygen furnace is disclosed. The method comprises providing an oxygen supplying conduit with a means of detecting the temperature of the supplied oxygen gas, a means of detecting the pressure thereof, and a means of heat-exchanging with the supplied oxygen gas, controlling the temperature and pressure of the oxygen supplied so that the stirring strength of the jet of oxygen gas and/or the flow rate of the oxygen gas are controlled independently of each other with the top-blowing lance being kept at a predetermined position.
