A device for the chemical analysis of solid or molten material samples, based on laser-induced emission spectroscopy, including a laser source generating a laser beam, a deflection device deflecting the laser beam, a focusing device focusing the laser beam, a device that guides the reflections of a plasma ignited by the laser beam on the material sample to an evaluation device. To arrange the laser source and the evaluation device remotely from the material sample, an arm having at least one movable joint and a cavity for the laser beam is provided between the laser source and the material sample for guiding the laser beam. The deflection device is shaped as a mirror or a prism and is provided at the articulation of the arm, whereby the laser source and the evaluation device are arranged to be independent of the material sample in terms of their movements.

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.

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 designed 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.

Method for installing and removing a lance into and from a metallurgical

There are disclosed a method and an arrangement for preventing the agglomeration of crusts in a lance opening passing a wall of a metallurgical vessel and provided for a lance carrying a measuring and/or sampling probe. During the metallurgical process proceeding within the metallurgical vessel and during the taking of a measurement and/or sample by means of a lance introduced into the metallurgical vessel through the lance opening, a gas that is inert relative to a melt bath contained in the metallurgical vessel, or air, is injected into the lance opening from outside, which gas produces a gas veil at the mouth of the lance opening facing the melt bath.

There is disclosed a metallurgical vessel, such as a steelworks converter, having a refractory brick lining and a probe opening passing a wall of the vessel for introducing a measuring and/or sampling probe. In order that the probe opening will get obstructed only minimally, if at all, and possible deposits of slag will be removed easily and quickly, the probe opening is provided with a lining of graphite or a graphite/alumina mixture.
