Patent number: 10161828Abstract: In a method for calibrating a polarization axis measuring device, both flat sides of a calibration element in a polarization axis measuring device are irradiated with polarized light, wherein the method involves aligning in each case at least one polarization direction of the light in a first and/or second rotational position with a principal axis in a predefined angular relationship with respect to a polarization axis of the calibration element. Determining the rotational position of an axis of the calibration element is carried out by determining an angle bisector between the first and second rotational positions of the polarization direction of the incident light. The method involves assigning a predefined angle value for the rotational position of the principal axis of the polarization direction for which the latter is in the predefined angular relationship with respect to the axis of the calibration element inserted as intended.Type: GrantFiled: April 15, 2016Date of Patent: December 25, 2018Assignee: RODENSTOCK GMBHInventors: Stephan Trumm, Johann Auer, Werner Müller

Patent number: 5835524Abstract: A scrap-melting electric arc furnace operating at an elevated melting power having a simple construction that also avoids thermal loads of the side wall caused by the electrodes. The electrodes are protected from damage during scrap-charging. The electric arc furnace includes a bottom for receiving a melt. An upper part rises from the bottom part and has side walls. A lid covers the upper part. A charging shaft is disposed approximately centrically relative to the upper part, and has a diameter that is substantially smaller than the diameter of the upper part. The charging shaft interior communicates with the furnace interior via an opening in the lid. Electrodes arranged approximately radially symmetrically are directed obliquely into the furnace interior and project toward the center of the electric arc furnace.Type: GrantFiled: February 28, 1996Date of Patent: November 10, 1998Assignee: Voest-Alpine Industrienlagenbau GmbHInventors: Harald Berger, Peter Mittag, Heinrich Auberger, Peter Wimmer, Johann Auer, Alfred Weber, Johannes Steins

Patent number: 5472178Abstract: In a device for controlling a plug (5) of a metallurgical vessel (1), in particular a distributing launder of a continuous casting installation, with a plug (5), which can be raised and lowered and which is supported in a support frame which is movable relative to the metallurgical vessel (1), the support frame for the plug (5), which can be raised and lowered, is supported outside of the metallurgical vessel (1) displaceable in a direction crosswise to the lifting direction of the plug (5) and can be releasably locked together with the metallurgical vessel. By means of this a simple separation of the plug mechanism (9) and the metallurgical vessel (1) is possible without operational elaboration and an exchange of the metallurgical vessel (1), for example, is made possible without having to dismantle the entire plug mechanism (5, 9).Type: GrantFiled: July 11, 1994Date of Patent: December 5, 1995Assignee: Voest-Alpine Industrieanlagenbau GmbHInventors: Leonhard Paar, Franz Hammerer, Gerhard Grabner, Walter Engleitner, Werner Brandl, Ernst Weninger, Johann Auer, Walter Schiman

Patent number: 5190719Abstract: A plant for the production of molten metals includes a melting vessel in whose wall burners and optionally oxygen-containing-gas feeding ducts are installed and on whose upper end a charging device as well as a gas evacuation duct receiving the offgases forming enter.In order to enable the continuous charging of the melting vessel by avoiding any unintentional escape of gas from the melting vessel, both the gas evacuation duct and the charging means run into the upper end of the furnace shaft laterally and approximately diametrically opposite each other. The charging means projects into a charging opening brushed over by a gas curtain and an intake chute for charging material is provided below the charging opening in a manner directed towards the center of the furnace shaft.Type: GrantFiled: November 6, 1991Date of Patent: March 2, 1993Assignee: Voest-Alpine Industrianlagenbau GmbHInventors: Wilfried Pirklbauer, Alfred Weber, Johann Auer
