Abstract: A ring-rolling mill (1) includes a machine table (2) for accommodating the rolled material (3) and an axial stand (4) that supports at least one axial roll, preferably two axial rolls (5, 6), for rolling the end faces (7, 8) of the rolled material (3). The ring-rolling mill and a method for operation thereof facilitate rapid product change without elaborate setting-up or without conversion of the rolling mill. For that purpose at least one pressure roll, preferably two pressure rolls (9, 10), for rolling the outer circumference (11) of the rolled material (3) is further arranged on the axial stand (4). The at least one pressure roll (9, 10) is arranged so as to be translationally displaceable relative to the axial stand (4).

Abstract: A strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5′ with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5′ and its emission into the environment, pollutants, primarily dust, located in the steam-air mixture 5′ are depleted by a separator 6, 6′.

Abstract: A pickling system for surface treatment, using a pickling medium, of strip steel in the form of standard steel, electric strip, high-grade steel, and extra-high-strength and ultra-high-strength third-generation steel in order to thereby provide a surface suitable for a subsequent shaping process for further processing. The system includes a plurality of treatment tanks connected in series. The pickling system has a modular construction and, starting from the strip infeed, at least one first treatment tank in the form of a dipping bath module is provided in the working direction, downstream of which a plurality of treatment tanks in the form of spray pickling modules are arranged, and at least one final second dipping bath module is arranged downstream of the spray pickling modules.

Abstract: The metallurgical furnace comprises a closed vessel enclosing a reducing atmosphere. The vessel comprises at least one electrode providing energy to a burden. The burden comprises a body of molten metal having an upper surface. A carbon injecting lance, in an operational position thereof, extends from an inlet end thereof outside the vessel through a port in the vessel to an outlet end thereof inside the vessel where the lance terminates below the upper surface. The inlet end is connected to a source of carbon. The lance being movable between the operational position and a retracted position wherein the outlet end is outside the vessel. The furnace further comprises a gastight enclosure for the lance when in the retracted position. The enclosure locates on the vessel in gastight manner and over the port and maintains the reducing atmosphere in the vessel.

Abstract: Tracing forged parts over their production process includes: capturing process parameters of a forging process; marking a workpiece with a first identifier; storing the captured process parameters and the first identifier in a database; reading the identifier from the workpiece produced in the previous process step; capturing process parameters during subsequent process steps; storing the process parameters of the subsequent process steps in the database for the read identifier, if legibility of the first identifier of the workpiece remains during the subsequent process step; marking the workpiece produced in the subsequent process step with a further identifier, if legibility of the first identifier of the workpiece does not remain during the subsequent process step of the production process; and storing the process parameters of the subsequent process step together with the further identifier and process parameters of the previous process steps and the first identifier in the database.

Abstract: A method for rolling a ring-shaped rolling product (5) having an open cylindrical cross section in a ring rolling machine (1) with inductive heating of the rolling product (5) during the rolling process uses at least one inductor (12) which is held at a predefined coupling distance relative to the rolling product (5) and is tracked or carried along during the shaping process in accordance with the change in dimensions of the rolling product (5). An alternating magnetic field, preferably with a frequency of between 4 and 10 kHz, is coupled directly into the rolling product (5) using the inductor (12).
