Abstract: Radial forging of long products made of metal workpieces in a radial forging machine uses at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted to simultaneously carry out the forging operation. An automatic pass schedule calculation includes entering start parameters for the radial forging process into a pass schedule calculation program and defining target parameters for the radial forging process. The pass schedule calculation program calculates a pass schedule or a forging sequence based on these start and target parameters. The pass schedule calculation program determines a temperature variation and the temperature distribution over the cross section of the long product and takes into account the change in shape during radial forging.

Abstract: A method for adjusting an inlet guide of a peeling machine controls a peeling material using the inlet guide in relation to a peeling head carrying peeling tools in such a way that the volume per unit length of the peeling material, which volume is to be machined by the peeling machine, is minimized while producing a bright steel having excellent surface quality. Furthermore, a peeling machine provides appropriate measuring equipment in order to be able to carry out the method described above.

Abstract: The present disclosure relates to a method for the pyrometallurgical smelting of metal-containing raw materials, waste materials and/or secondary waste materials (M), wherein these are fed in shredded form to a smelting unit (1) which includes a smelting zone (6), a main reaction zone (7) and a secondary reaction zone (8) and are smelted in the presence of an oxidizing, reducing and/or inert gas and/or gas mixture (G), such that a liquid melt phase (9), a liquid slag phase (10) and a gas phase are formed. The oxidizing, reducing and/or inert gas and/or gas mixture (G) is supplied in compressed form via at least one injector (11) and is expanded adiabatically within the smelting unit (1) and is then injected as adiabatically expanded gas and/or gas mixture into the liquid slag phase (10).

Abstract: In order to be able to determine the rolling or guiding gaps of the roll stands or guide stands in a multi-stand rolling mill, at a predetermined measurement precision, with the least possible effort, a master calibration and intermediate calibrations are carried out, wherein various calibration measures are refrained from, in a targeted manner. The targeted lack of recourse in the case of specific calibrations is also independently advantageous.

Abstract: A method for producing a metallic strip or sheet, in which the strip or sheet is rolled in a multi-stand rolling mill and is discharged downstream of the last roll stand of the rolling mill in a conveying direction. The strip or sheet is cooled in the multi-stand rolling mill and/or downstream of the rolling mill as viewed in the conveying direction, wherein a temperature of the strip or sheet is measured upstream of the last roll stand of the rolling mill as viewed in conveying direction. Based on this measured temperature, a temperature for the strip or sheet at the exit of the last roll stand of the rolling mill is then determined by calculation with the aid of a temperature calculation model, with which further temperature processes of the manufacturing method can be controlled or regulated after a comparison with a predetermined reference value.

Abstract: The invention relates to a method for the granulation of a metallurgical slag, wherein liquid slag (1) is atomized by blowing air (2) onto it and the slag particles (3) granulated in this way are collected. In order to ensure a high quality of the granulate and operate in the most energy-efficient manner possible, the invention provides that the atomization is done by blowing heated air jet (2) free from the addition of water onto the liquid slag (1) and the slag is supplied to a working chamber (4), wherein the granulated slag particles (3) are collected in the floor region of the working chamber (4), wherein the air (5) escaping from the working chamber (4) is either supplied to a heat exchanger (6), which preheats the air jet blown onto the liquid slag (1), or directly recirculated in order to atomize the liquid slag (1).

Abstract: A device for measuring a wear condition on the plain bearing surface of a sensor plate comprises a measuring apparatus, which has wear sensors of a sensor plate integrated into the plain bearing surface. To capture the material removal at the plain bearing surface due to wear an evaluation apparatus is in signal connection with the wear sensors. The evaluation apparatus is designed, with respect to programming, in such a way that a change, in particular an increase, in the ohmic resistance value of the electrical conductor of a certain wear sensor can be captured in dependence on its own material removal, in order to thereby ensure that the amount of the material removal at the plain bearing surface and/or the remaining thickness of the plain bearing surface at the location of said certain wear sensor can be inferred from the detected change in the resistance value.

Abstract: A method for setting different cooling rates of metal strips or metal plates (rolling material) over the strip width of a cooling stretch in a hot-strip mill or heavy-plate mill is presented. According to the method, for the calculation of the cooling rate, the initial enthalpy distribution over the material width of the rolling material before the cooling is determined. Proceeding therefrom, a target enthalpy distribution is determined in the width direction and length direction of the rolling material while taking into account a calculation of the flatness and the mechanical properties by means of a microstructure model. Subsequently, the coolant amount and the coolant curve of the cooling stretch are set.

Abstract: A flatness-measuring device for a hot-rolled strip within a hot-rolling mill includes an entry-side deflection roller and an exit-side deflection roller. A central deflection roller is arranged between the entry-side deflection roller and the exit-side deflection roller. The central deflection roller is used as a flatness-measuring roller. To prevent the hot-rolled strip from departing laterally during a flatness measurement, the flatness-measuring device has a sensing apparatus for sensing an actual position of the hot-rolled strip. An adjusting apparatus is connected to the sensing apparatus and to at least one of the deflection rollers. The flatness-measuring device is designed to vary an angle between a longitudinal central axis of the deflection roller respectively connected to the adjusting apparatus and a longitudinal axis of the flatness-measuring device based on a deviation of the actual position of the hot-rolled strip from a predefined target position.
