摘要： A method for treating molten metals (4) and/or slags in metallurgical baths comprises the introduction of a process gas into a melt bath. The process gas is accelerated to supersonic speed and is introduced below the melt bath surface (5) by means of at least one supersonic nozzle (6) with supersonic speed into the liquid phase of the molten metal (4) and/or into the slag and/or into the region of a phase boundary between molten metal and slag. The disclosure further relates to a metallurgical plant for treating molten metals.

摘要： A lance for conducting a pyrometallurgical operation by top submerged lancing (TSL) injection, has inner and outer substantially concentric pipes. The lower end of the inner or at least a next innermost pipe is set at a level relative to the lower end of the outer pipe required for the pyrometallurgical operation. The relative positions of the inner and outer pipes are longitudinally adjustable to enable the length of the mixing chamber to be maintained at a desired setting during a period of use to compensate for the lower end of the outer pipe wearing and burning back.

摘要： The inventive method consists in introducing a stirring gas through the vessel (1) bottom, in receiving a measurable mechanical vibration by at least one sensor fixed to the vessel or to the supporting frame thereof, in filtering the thus detected vibration signals by a high pass filter (13a) and preferably by a low pass filter (13b), in sampling and digitising (15) said vibration signals for exposing them to a second filtering which is digital and calibrated upon the vessel vibration responses, in sequencing said responses, in exposing each sequence to the calculation (17) of a temporal moving mean square, in extracting the total effective value RMS (for ‘Root Mean Square’) of the measured vibration signal therefrom, wherein said effective value is used for controlling the stirring gas flowrate supplied to the vessel. Said invention can be used for the stirring stand of steel making shop ladles, converters, RH processes, electric arc furnaces, etc.

摘要： A mechanism and flow conduits for introducing and transporting a set of separated fluids and a stream of solid fines through passageway in a rotating metallurgical converter for introducing such fluids and solid fines into a liquid metal contained in the converter.Stationary conduits from flow sources connect to a non rotative sleeve which forms the external portion of a rotary joint able to introduce a set of separated fluids into the rotating converter passageways. Each separated stationary fluid conduit connects to port holes in the fixed sleeve to lead the flow to the interior of the sleeve, and connects a circumferential channel formed in rotating rings located between a rotating shaft affixed to the converter vessel trunnion pin and the static sleeve with a seal between each adjacent ring and corresponding channel. A port hole is located in each rotating channel ring for leading the fluid through internal flow paths inside and along the axis of the shaft body.The flows paths connect to a plurality of pipes contained inside the trunnion pin central bore, which, in turn, connect a set of port holes of a multi passageway elbow, which serves for leading the fluids and solid fines stream to the ring side end of the trunnion pin and changes the direction of the fluids and stream of solids by ninety degrees so as to direct such fluids to the botton pipe lines which finally end up in the converter bottom injection nozzles.
