Abstract: A metallurgical vessel has a metal outer shell (7) and a refractory lining (8, 9) arranged on the inside of the metal outer shell (7) and an opening (1) which passes through the wall (3) of the vessel (4) and is intended for the introduction of a lance-like metallurgical implement, preferably a measuring and/or sampling probe (2). To prevent clogging of the opening (1), the metallurgical vessel (4) has the following features: - the opening (1) is formed, viewed from the outside inwards, from a part (12) tapering to a narrow region (11) and a part (13) diverging from said narrow region (11), - the tapering part (12) is lined with a metal shell (14) and - the diverging part (13) is provided, at least partially, with a metal reinforcement (16, 16') having a gas supply device (20) (Fig. 1).

Abstract: 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.

Abstract: A device for reception and transmission of electromagnetic waves in the visible and/or infrared spectral region and/or the UV-region, emitted by a gaeous, liquid or solid material sample, to an analytical unit, preferably for the determination of the temperature of the material sample. The device comprises a heat-resistant sleeve, open at the front end, with a light wave guide coupled to the analytical unit. In order to record the electromagnetic waves of high intensity, the device has a heat-resistant protective element, arranged at the front end region of the sleeve, which conducts electromagnetic waves.

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: En un método para determinar ondas electromagnéticas que se originan desde el interior de un fundido (3), en particular un fundido metálico, se forma un espacio (26) hueco lleno de gas dentro del fundido (3) al soplar en el interior gas, y se observan las ondas electromagnéticas emitidas desde el fundido (3) a través del gas soplado en el interior, evaluado mediante alimentacion de las ondas electromagnéticas vía un sistema (20) optico a un detector (22) para determinar la temperatura y/o composicion química. Con el fin de evitar falsificacion de los valores medidos, las ondas electromagnéticas emitidas son limpiadas de ondas electromagnéticas (36, 37, 39, 40) dirigidas oblicuamente al eje (38) optico del sistema (20) optico y se presentan más allá de un radio (41) límite extraído del eje (38) optico del sistema (20) optico, al refractar tales ondas electromagnéticas (36, 37, 39, 40) alejándolas del eje (38) optico del sistema (20) optico, en un medio (42) de dispersion de ondas del sistema (20) optico, y unicamente las ondas electromagnéticas dirigidas aproximadamente paralelas al eje (38) optico del sistema (20) optico llegan a un detector (22) colocado para seguir al sistema (20) optico y/o el sistema (20) optico se mueve en relacion al espacio (26) hueco mientras se ajusta su eje (38) optico, hasta que la intensidad de las ondas electromagnéticas emitidas alcanza un máximo durante la evaluacion de las mismas (figura 2).
