Abstract: A metallurgical vessel, such as a converter, a ladle or an electric arc furnace, has coolant gas channels (10) on the internal side (6) of its steel jacket (1), under its refractory lining (7, 8, 9.) The coolant channels are connected to a gas feed duct (12) and, if desired, to a gas discharge duct (16, 17). Preferably the coolant is air, saturated or oversaturated with water.

Abstract: An arrangement for introducing and removing a lance into and out of a tiltable metallurgical vessel has drive means stationarily arranged in the direction of the lance axis and means for pivotal mounting of the drive means.The lance is deoigned as a guide and is guided by the drive means and is movable in the direction of its axis. In a method using the above arrangement for positioning the lance relative to the metallurgical vessel, the actual position of the vessel is taken up by a position transmitter on said vessel, and the drive means is actuated to position the lance in dependence on that actual position.

Abstract: Process control for molten metal involves using a dynamic computer process model together with a correction model. To produce a molten metal in a metallurgical plant, a process model is used with the plant computer control. The process model has the behavior for at least one variable process parameter between an actual process value, a setting value, and a final process value. The process model takes the actual process value data to a given time point, as the temperature and/or the chemical composition where a computer simulation gives the direct time point where the actual process value gives the final process value at a later point in time. On deviations of the simulated process value from a nominal value, corrections are computed and the actual process value is altered accordingly. The actual process value is repeated from the data taken to the further time point. The process module has at least one module with intelligent self-optimizing e.g. with a neural network.

Abstract: The method uses a measuring device which blows a gas into the melt (3) to form a gas-filled cavity (26), with detection of the electromagnetic UV or IR radiation emitted into the latter via an optical system (20) and an associated detector (22). The optical system has a wave scattering device (42) for elimination of the electromagnetic waves oblique to the optical axis (38) of the optical system. Only the waves parallel to the optical axis are received by the detector and/or the optical system is displaced and the optical axis aligned until the detector signal reaches a maximum value.

Abstract: A process and apparatus for processing a shredder light fraction including multi-duct nozzle having at least an end section positionable within a metallurgical vessel containing a molten metal bath. The shredder light fraction may be fed into the molten metal bath while using only small quantities of carrier gas, e.g., air or nitrogen, and protective gas, e.g., hydrocarbon or inert gas. The shredder light fraction and the carrier gas may be injected into the molten metal bath as a main jet and oxygen may also be injected into the molten metal bath as a secondary jet. The primary jet and the secondary jet may be surrounded by a gas jet formed by the protective gas being injected into the molten metal bath.
