Abstract: A method and a device serve for treating primary gas from a metallurgical vessel for the effective reduction of NOx constituents. The primary gas is supplied with a reducing agent. Additionally, secondary gas is suctioned at an auxiliary suction point in the surroundings of the metallurgical vessel. The primary gas is mixed with the colder secondary gas to produce a gas mixture. Thereby NOx constituents in the primary gas are effectively reduced without an undesired reactive influence on the process within the metallurgical furnace and without requiring high investment costs. This is achieved in that the primary gas is mixed with the secondary gas prior to supplying the reducing agent, namely such that the gas mixture is cooled to a temperature ranging from 400° C. to 600° C. prior to supplying the reducing agent, and the reducing agent is then supplied to the gas mixture, containing the primary gas.

Abstract: A device for handling mandrel rods in a rolling plant for rolling seamless tubes comprises an inserter. The inserter moves a mandrel rod in a rolling direction such that the mandrel rod, starting from an initial state, is pushed into a tube blank situated upstream of the mandrel rod. A retaining device has a fixing unit that is movable along the rolling line and is designed to temporarily hold the mandrel rod at an action point at a rear end of the mandrel rod and to carry out a working stroke. The mandrel rod can be inserted into the rolling mill in the rolling direction and pulled out of the rolling mill counter to the rolling direction by the retaining device. The retaining device is designed such that the starting position of the fixing unit lies between the two ends of the mandrel rod in the initial state.

Abstract: A method for controlling a cooling device which is set up to control temperature of a rolling stock such as a metal strip, which runs through a cooling device along a conveying direction of a rolling train. The cooling device is arranged upstream of the rolling train. The method includes determining total enthalpy of a system formed by the rolling stock; determining a measure for the formation of scale, which includes a scale factor that depends on chemical composition and surface temperature of the rolling stock, and a heat transfer coefficient of the scale; calculating a temperature distribution and/or average temperature in the rolling stock based on a temperature calculation model, in which the determined total enthalpy and the measure for the formation of scale are included; and setting a cooling capacity of the cooling device taking into account the calculated temperature distribution and/or average temperature in the rolling stock.

Abstract: A method for operating a system of the iron and steel industry for producing a metal product with participation of a severing or forming device. The actual value of an indicator be calculated over a length section of the metal product for the metal product to be produced. The indicator represents the resistance of the metal product to severing or forming processes. The calculated actual value pIst for the indicator p is then compared to a predefined threshold value. The severing or forming also only actually takes place when the actual value of the indicator of the metal product is less than the threshold value. If a comparison should show that the actual value of the indicator is greater than the threshold value, before the severing or forming of the metal product, a local processing of the metal product is performed in the corresponding length section.

Abstract: A system for winding a rolled product includes a winder having a winding spool, a spool rotator, a distributor guiding positioning of the rolled product towards the spool at an instantaneous winding point, and a distributor translator. A control and command unit coordinates the rotator and the translator according to a predetermined winding program which is a function of predetermined reference operating parameters and of real time operating parameters. The detector includes a laser triangulation profilometer diametrically opposite to the distributor, and continuously detects the surface profile of the coil of rolled product at every added turn. A processing and calculation unit feedback adjusts translation speed of the distributor to minimize a difference between an actual operating parameter calculated based on the profile of the coil in formation detected by the profilometer and the same operating parameter calculated based on theoretical data related to a predetermined ideal coil winding.

Abstract: The invention relates to a method and a vacuum-coating system (10) for coating a band-type material (11), in particular made of metal. For this, the band-type material (11) is moved, via a conveying section (12), in a transport direction (T) and is vacuum-coated within a coating chamber (14), in which a vacuum is applied. As seen in the transport direction (T) of the band-type material (11), at least one flatness optimization device (39) is arranged upstream of the coating chamber (14), through which flatness optimization device the band-type material (11) can be guided. In this way, a desired flatness is generated for the band-type material (11).

Abstract: A device and a method for producing a continuous strip-shaped composite material. For this purpose, a base material, which is produced using at least one casting machine as a continuous strand, in particular made of steel, and providing at least one cladding material, which is unwound in the form of at least one metal strip by a coil unwinding unit are provided. Subsequently, a slab which has formed by solidification from the strand produced by the casting machine and the metal strip unwound by the coil unwinding unit, in the hot state are brought together, wherein the materials, which are moved in the direction toward one another, formed from the slab and the unwound metal strip are hot rolled, so that a single continuous strip-shaped composite material is thus produced by roll cladding. The base material is continuously cast in the vertical direction in the casting direction.
