Abstract: A composite body includes a main part made of a molybdenum-based material, on at least sections or portions of which a tungsten-carbide-containing coating is formed. The coating has a microstructure that consists or is formed substantially of fine or microcrystalline and/or nanocrystalline tungsten carbide grains. A method for producing a composite body is also provided.

Abstract: A support frame for holding a radiation shield for a high-temperature furnace is configured to connect the radiation shield to a wall of the high-temperature furnace and to space the radiation shield from the wall at a normal distance. The supporting frame has at least one holding element which is inclined in relation to a normal distance direction at an angle at least in sections between the radiation shield and the wall and is configured to be rotatable and/or flexible at least in sections in such a way that a lateral expansion of the radiation shield brings about an increase in the angle and therefore a reduction in the normal distance. An arrangement including a cover or a side wall for a high-temperature furnace and a support framework, as well as a high-temperature furnace with a support framework, are also provided.

Abstract: A shielding module for a high-temperature furnace has a packet of interconnected shielding plates. The packet of interconnected shielding plates is mounted to a common base body. The base body has fixing points for fixing to base bodies of other shielding modules of the same kind.

Abstract: A ceramic holding element for a high-temperature furnace includes at least one fastening portion formed on a part of the holding element surface for mechanically connecting the holding element to a supporting structure. At least one heat conductor receiving portion on a part of the holding element surface receives a heat conductor. At least one groove is formed on a peripheral part of the surface of the holding element between the fastening portion and the heat conductor receiving portion. The groove extends substantially over the entire periphery of the peripheral part and at least one imaginary path between the fastening portion and the heat conductor receiving portion along the holding element surface crosses the groove. The groove has an aspect ratio, formed by a depth to width ratio of the groove, being greater than or equal to 1.5.

Abstract: A holding device for a heating element and a heater with at least one such holding device. The holding device is produced from a refractory metal or from an alloy on the basis of refractory metal, has at least two holding elements which are arranged perpendicularly or at least substantially perpendicularly to each other. A first holding element is at least partially arranged in an opening of a second holding element.

Abstract: An electrical heating conductor arrangement for heating a furnace has one or more strip-shaped portions with a generally horizontal sheet-like extent. The strip-shaped portions are formed by individual bands which have along their width an arcuate curvature with respect to a horizontal plane. The individual bands are partially mounted by at least one bearing element pivotably in the longitudinal direction of the respective band.
