Abstract: The invention concerns a process for fitting a gas-injecting nozzle in the wall of an installation. The process is characterized in that: an external supporting surface (11) whose shape matches the so-called internal supporting surface (12) of the passage (6) provided in the bedding brick is associated with the nozzle (2); the nozzle is placed opposite the passage (6) in the bedding brick; the nozzle (2) is moved in axial translation so as to adjust the position thereof along the longitudinal axis of the passage and move the front face of the nozzle into a desired initial position; the nozzle is locked in this desired initial position; and, at least periodically, the nozzle is inserted further forwards into the passage in the bedding brick in order to compensate the wear in the front face of the nozzle. The invention can be used to prevent clogging, such as in a cement-producing plant.

Abstract: A lance (14) comprising a first elongate tube (28) extending through an elongate tubular shroud (30), is used for top submerged injection of a fluid such as air (possibly including oil or particulate coal) into a liquid pyrometallurgical bath (18) comprising slag or having slag on its surface. The first tube (28) defines a duct (38) for the flow of the fluid. The shroud (30) defines a flow passage (40) for a coolant such as air. The shroud (30) terminates above the lower end portion of the first tube (28). In use, the coolant cools the lance (14) and discharges above the bath (18) when the outlet of the first tube (28) is inserted into the bath (18). A furnace installation (10) comprises a lance (14), a furnace (12), and a lowering means (32).

Abstract: An annular nozzle for an oxygen lance, e.g. an oxygen lance for blowing steel in a converter, gives an annular hot spot on the liquid steel in the converter. When exiting the nozzle, the annular jet has disruptions that result in ambient atmosphere being sucked in towards the centre of the annular jet. Thus, a sub-pressure is prevented which would otherwise prevent the jet from diverging conically. In one embodiment, the nozzle can be switched during a blowing operation between forming a tight jet and forming a diverging jet.

Abstract: The disclosure relates to a method for scavenging of gas through a melt in a ladle by a nozzle disposed in the bottom of the ladle. By varying the gas pressure, the nozzle is caused to assume one open and one substantially closed position. At a low gas pressure, the nozzle allows the passage of a gas flow which is sufficient to keep the nozzle free of the melt but is insufficient to influence the melt proper. At a high gas pressure, the nozzle allows the passage of a gas flow of such magnitude that agitation and refining of the melt take place. The nozzle is, in this instance, of a cross-sectional area of the order of magnitude of between 0.2 and 15 mm . The differential pressure at substantially closed nozzle, i.e. the difference between the gas pressure in the nozzle and the ferrostatic pressure from the melt, is greater than 0.05 bar, and the differential pressure at open nozzle lies in the range of between 5 and 250 bar.
