摘要： [Problem] It is to provide a converter steelmaking method capable of efficiently performing dephosphorization refining in the production of molten steel by simultaneous decarburization refining and dephosphorization refining of molten iron in a converter, which is advantageous over the conventional method.
[Solution] In a converter steel making method by supplying gaseous oxygen into a converter to perform decarburization refining of molten iron while adding a powdery CaO-containing dephosphorizing agent to form a slag of the dephosphorizing agent to perform simultaneous decarburization and dephosphorization of molten iron to thereby produce molten steel, the dephosphorizing agent is supplied to a bath surface of the molten iron together with at least one gas jet from the top blowing lance and a dynamic pressure when the gas jet from the top blowing lance is impinging onto the bath surface of the molten iron is controlled to an appropriate value in consideration of an increase due to the kinetic energy of the accompanying dephosphorizing agent.

摘要： A method of refining molten metal in a vessel by the reaction of oxygen with impurities in the molten metal comprises the steps of: a) ejecting at least one primary jet of oxygen from a lance positioned above the molten metal into the molten metal to react with impurities therein and to form a layer of molten slag; b) continuing to eject the primary jet of oxygen from the lance and thereby causing the primary bet of oxygen to pass through the slag layer into the molten metal; c) ejecting a plurality of secondary jets of oxygen from the lance, the secondary jet of oxygen travelling for a distance separately from the primary jet of oxygen; and d) entraining the secondary jets of oxygen into the primary jet of oxygen upstream of the entry of the primary jet of oxygen into the molten metal. A lance head for use in the method has at least one primary oxygen port and a plurality of secondary oxygen ports, the axis of the second oxygen port diverging in the direction of flow from the primary oxygen port at an angle of up to 45°. The method and lance head are particularly of use in the Basic Oxygen Steelmaking (BOS) process. If desired, a stirring gas such as argon may be mixed with the primary oxygen.

摘要： Apparatus for injecting gas into a vessel including a gas flow duct 31 which receives hot gas through a gas inlet structure 32 at a rear end of the duct. An elongate central structure 33 extends throughout the length of duct 31 and carries a series of vanes 34 for imparting swirl to the gas flow exiting the forward end of the duct. The forward end of duct 31 has an internally water cooled tip 36 and water flows to and from tip 36 through annular passages 43, 44 in the wall of duct 31. tip 36 comprise a hollow shell internally divided by a partitioning structure to form a series of water flow galleries each extending circumferentially around the tip and interconnected for flow of cooling water sequentially through the galleries from the water supply passage 43 to the water return passage 44. The partitioning structure also provides a structural interconnection between inner and outer tubes 37, 39 of the duct wall to transfer gravitational load force from the inner tube to the outer tube when the apparatus is supported vertically through the outer tube.

That is, the process is as follows. A process for dephosphorizing a hot metal, wherein oxygen is top blown into a hot metal and a flux containing as a major component a component that is one or at least two substances selected from quick lime, limestone and iron oxide and that contains at least iron oxide is blown thereinto with oxygen, an inert gas or a mixture of the two gases used as a carrier gas, characterized by that the process including the step of blowing the flux into a hot metal in such a manner that the ratio of a mass of CaO in the blown flux to a total mass of oxygen (CaO/O) contained in iron oxide in the blown flux and in the carrier gas exceeds 2.5. Moreover, the present invention provides a process for dephosphorizing a hot metal comprising blowing the flux into a hot metal in such a manner that the proportion of solid oxygen based on the entire oxygen added becomes from 5 to 40% by mass.

摘要： When decarburization blowing is carried out using a top-blow lance having at least one independent system of gas feed pipes; while the nozzle absolute secondary pressure Po of the lance of at least one system is kept in a range of 0.7 to 2.5 times the nozzle optimum expansion absolute secondary pressure P of the lance, the oxygen feed speed is changed by changing the nozzle absolute secondary pressure during the blowing by the system so that its maximum value is at least 1.1 times its minimum value. The top-blow refining method uses a top-blow lance having a slit-like nozzle which has two to ten shield portions disposed at a part of the opening at the end of the lance, has a concentric polygonal or circular cross section, has a ratio B/h of 10 to 225 where B (mm) is the long side of the openings separated by the shield portions and h (mm) is the short side, and has a value (B.h)R of 0.4 to 4 mm where R (mm) is the lance diameter R (mm), and one to six circular nozzles connected to a gas feed pipe independent of the slit-like nozzle and disposed inside the concentric polygon or circle.
