A system and method for measuring the inner space of a container provides for the measurement of the wear of the lining of a container such as a torpedo ladle optionally while the ladle is still hot. The interior lining of the container is scanned by a scanner head from a first position in the container which is at an angle relative to the vertical axis of the container. The scanner head is placed in a second position in the container at an angle relative to the vertical axis of the container and from the second position the scanner head scans the portions of the interior lining of the container which were not scanned during the first position scan. By comparing the scanning measurements of the lining from the first position scan and the second position scan after the container has been loaded and unloaded with an initial reference measurement of the lining the wear of the lining can be measured.

A method of a method for measuring wear in the lining of a metallurgical melting vessel such as a steel converter (), by a laser scanner () A laser having a contouring system on a cart can be moved between measurements The laser contouring system references three permanent marks behind the cart (PM, PM, PM) and two temporary marks positioned near the vessel (TM, TM) The distances from the movable cart to each of the five marks is determined during an initial measurement by the contouring system Every time the cart is moved and a new measurement is taken, the contouring system scans the vessel and the two temporary marks but not the permanent marks.

An optical beam separation element for a measuring apparatus includes a reflecting component with a reflecting surface and an aperture for forming an optical channel common to the transmission and the reception directions in the optical beam separation element. The reflecting surface of the reflecting component is positioned at an angle with respect to the optical channel. The aperture extends from the reflecting surface through the optical beam separation element allowing the optical beam to pass through the optical beam separation element to the optical channel in the transmission direction. The reflecting component separates the optical beams of the reception and the transmission directions.

To determine the carbon black distribution two measurements of spectral intensities of separately produced plasmas are carried out with different time delays relative to a particular laser pulse, the time delay for the second measurement for determining the spectral line intensities of a reference element carbon (I.sub.C') and at least one analysis element (I.sub.A.n') being smaller than for the first measurement; for determining the spectral line intensities of the reference element (I.sub.C) and the other analysis elements (I.sub.A.n). Evaluation of the measurements is performed by reference to calibration information based on reference measurements, which information shows the magnitude of the concentration ratio of the other analysis elements or the at least one analysis element to the reference element (c.sub.A.n /c.sub.C or c.sub.A.n /c.sub.R) as a function of the appurtenant intensity ratio values. By comparison between the intensity ratio values from both measurements with the calibration information, using the concentration of total carbon (c.sub.C) and that of the selected analysis element (c.sub.A.n), the magnitude of the carbon black concentration (c.sub.R) is determined.

To determine the carbon black distribution two measurements of spectral intensities of separately produced plasmas are carried out with different time delays relative to a particular laser pulse, the time delay for the second measurement for determining the spectral line intensities of a reference element carbon (I.sub.C,) and at least one analysis element (I.sub.A.n,) being smaller than for the first measurement; for determining the spectral line intensities of the reference element (I.sub.C) and the other analysis elements (I.sub.A.n). Evaluation of the measurements is performed by reference to calibration information based on reference measurements, which information shows the magnitude of the concentration ratio of the other analysis elements or the at least one analysis element to the reference element (c.sub.A.n /c.sub.C or c.sub.A.n /c.sub.R) as a function of the appurtenant intensity ratio values.

A method of analyzing elements of a metal melt contained in a melting vessel comprises the following steps: introducing an inert gas at a temperature in excess of 300.degree. C. laterally into a tube passing through a lateral wall of the melting vessel and opening thereinto; generating a laser beam; passing the laser beam through an adjustable first lens system; reflecting the laser beam by a mirror into the tube; guiding the laser beam through a quartz window which closes the tube; generating a plasma in the tube by focusing the laser beam by the adjustable first lens system onto the surface of the metal melt in the tube; guiding the light generated by the plasma through the quartz window to an adjustable second lens system; coupling the light by the adjustable second lens system with an optical waveguide; and introducing the light by the optical waveguide into a spectrometer.
