The invention concerns a method for feeding an optical cored wire into a molten metal bath and an immersion system and an immersion nozzle to carry out the method. The optical cored wire (6) is decoiled, a feeding and straightening device (4) with a plurality of rollers (20, 21) conducts feeding of the optical cored wire (6) in a feeding direction towards the metal bath (11) as well as a first straightening of the optical cored wire (6), and subsequently a separated further plurality of non-motor driven nozzle straighteners (13) arranged between the feeding and straightening device (4) and the metal bath (11) conducts a second straightening of the optical cored wire (6). Very high precision of temperature measurement can thereby be achieved.

A method for the handling of melt samples in a steelworks laboratory may involve processing and/or analyzing a melt sample in at least one first treatment apparatus and subsequently transporting the melt sample via at least one first transport path to at least one second treatment apparatus where the melt sample is subjected to further processing and/or analysis. As part of the transporting step, the method may involve clamping the melt sample on a sample carrier so that the sample carrier is transported together with the clamped-in melt sample between the treatment apparatuses and is positioned in the treatment apparatuses for processing and/or analysis.

The invention relates to a method and a device for quantitive determination of a number and size of particulate components contained in a medium flowing along a flow channel. Ultrasonic waves are coupled into the flowing medium, which are reflected at least partially by the particulate components and reflected ultrasonic wave portions which are detected in a ultrasonic time signals, on which the quantitive determination is based. Amplitude values associated with the individual ultrasonic time signals, are detected which are each greater than an amplitude threshold value established for each ultrasonic time signal: The detected amplitude values are assigned to values describing the size and the number of the particulate components.
