  • Patent number: 5227118
    Abstract: The present invention relates to a refining lance. It relates more particularly to a lance of the kind used for supplying from above, onto a metal bath, the oxidizing gas required for refining the molten metal contained in a metallurgical vessel. It includes a rotating device to divide the refining gas flow into an even number of separate gas jets that are more or less identical. The gas jets exit the head of the lance in angles which are substantially equal with respect to the longitudinal axis of the lance but in diametrically opposite directions with respect to the said axis.

  • Patent number: 5037069
    Abstract: The invention relates to an automatic coupling for coupling lances used in steel production to a coupling head of a lance carrier, the required materials and cooling liquids being supplied to the lance through the coupling head.Coupling takes place by means of coupling hooks (4) which are provided on the coupling head (6), mounted by means of eccentrics (12), and vertically movable by actuation of these eccentrics (12).

  • Patent number: 4993691
    Abstract: A gas injection lance for use in metal refining is disclosed. The lance includes a tube having an inner diameter profile and a throttle member slidably received with the tube. The tube and throttle member define an annular gas flowpath. The throttle body may be moved axially within the tube to modify the characteristics of the flowpath.

  • Patent number: 4971297
    Abstract: Nozzles for a refining lance are presented which are spaced upwardly from the head of the lance and supply post-combustion oxygen to the space above a molten metal bath undergoing refining. Each of the nozzles has a mouthpiece with two parallel sharp edges which are arranged in planes passing substantially through the axis of the lance and which are connected by slightly rounded edges. Above the mouthpiece of each nozzle is a converging part.

  • Patent number: 4893791
    Abstract: An automatic lance changeover device is presented wherein a radially guided ring is axially vertically displaceable by two lifting spindle systems provided on each side of the ring and bears pivotable hooks for receiving the lance and for pressing the latter axially against a sealing surface on the coupling head. The hooks are connected to the stationary coupling head via pivotable connecting rods whose length is alterable, these connecting rods being eccentrically articulated on the support pin of the hooks with the bearing bore at the coupling head end of the connecting rods having a larger diameter than the associated wrist pin. When the ring is axially displaced, the hooks, which have swung out, in a first phase, initially surround the supporting pins on the upper part of the lance as the ring is displaced further, the hooks, without executing any further pivoting movement, pull the lance head into sealing contact with the coupling head.

  • Patent number: 4730784
    Abstract: A nozzle for the refining of metals by oxygen blasting from above the melt is presented. The nozzle includes a nozzle head having a blast pipe therethrough upstream of the mouth of the nozzle. The blast pipe directs a jet of gas comprised, at least in part, of oxygen, having a supersonic speed onto the melt. The blast pipe includes an inner tube. The lower portion of the inner tube has a throat positioned between a convergent and divergent sections, this lower portion defining a laval nozzle. The blast pipe also includes an outer tube coaxial with the inner tube and having a greater cross section than the inner tube. The mouth of the inner tube is spaced back (downstream) from the mouth of the blast pipe. The inner and outer tubes are each provided with flow control valves, and are connected to sources of pressurized gas. Devices are provided to vary the cross sectional area of the mouth of the inner tube.

  • Patent number: 4730813
    Abstract: A nozzle for refining metals or ferroalloys by oxygen blasting from above the melt is presented. The nozzle terminates at a nozzle head and includes at least one central blast pipe for directing a jet of oxygen having supersonic speed. A chamber is interposed between the mouth of the blast pipe and the mouth of the nozzle head. This chamber widens progressively from the mouth of the blast pipe, and narrows toward the mouth of the nozzle head. At least one opening from at least one lateral duct opens to the chamber in the vicinity of the blast pipe mouth. Each lateral duct is connected to a source of gas, and includes an inidividual flow control valve. Preferably, at least three lateral ducts are arranged symmetrically around the blast pipe mouth.

  • Patent number: 4730814
    Abstract: A blast pipe for delivering refining oxygen to the space above a metal bath in a refining operation is presented. The blast pipe is positioned in a gas supply duct and is provided with a pressure regulating valve. The blast pipe comprises a fixed straight wall portion along which the gas flows in a linear path. The straight wall portion terminates at a sharp edge, constituting a portion of the blast pipe exit orifice. A bent wall segment is located adjacent to and downstream of the straight wall portion and connects the remainder of the straight wall portion to the exit orifice. The bent wall segment preferably has a convergent configuration, upstream of the sharp edge, and a divergent configuration downstream thereof. The exit orifice, in cross section, has the shape of a rectangle, one of the long sides of which constitutes the sharp edge.

  • Patent number: 4052044
    Abstract: A method of removing encrustations from a metallurgical lance comprising the steps of relatively displacing the lance and a tool with the tool in contact with a layer of encrustation on the lance and applying a repetitive movement to the tool against the layer to dislodge the layer from the lance and permit the layer to fall therefrom by its weight.
