Abstract: Energy-efficient production of a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1), which modifies the known processes for producing a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1) so that the ferritic hot-rolled strip (6) can be produced significantly more energy-efficiently but nevertheless has good metallurgical properties and a good surface quality.

Abstract: A combined casting and rolling installation that produces hot-rolled strip with a final thickness<1.2 mm, and includes a first continuous casting installation and a second continuous casting installation, each producing slabs from liquid steel; a slab manipulator that conveys the slabs into a walking beam furnace that conveys the slabs into a rolling installation and heats the slabs to rolling temperature. The rolling installation includes a rough rolling mill forming rough-rolled strips from the heated slabs; a coil box forming a coil from the rough-rolled strip and unwinding the rough-rolled strip; a joining device forming an endless rough-rolled strip by connecting its ends without filler material; a multi-stand finishing rolling mill finish-rolling the endless rough-rolled strip to form a finished strip with the final thickness; a cooling section forming the hot-rolled strip; and a plurality of coiling devices coiling the hot-rolled strip.

Abstract: A device for stabilizing of working rollers and back-up rollers of a mill stand that has, for each bending block, first hydraulic pressing units being arranged upstream of the working roller, each first hydraulic pressing unit having a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the bending block and the pressure plate being pressable against a working roller chock, and for each stand column, at least one second hydraulic pressing unit, the second hydraulic pressing unit being arranged downstream of the back-up roller and having a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the stand column and the pressure plate being pressable against the back-up roller chock, and a first hydraulic pressing unit containing a first oscillation absorber.

Abstract: A method and an installation for inductively heating flat objects that are transported in a feed direction. The installation has at least one transverse field inductor device which extends transversely to the feed direction over the width of the flat object and has a longitudinal axis running parallel to the transverse axis of the flat object. The transverse field inductor device is positioned such that the longitudinal axis extends in a vertical plane obliquely with respect to the transverse axis of the flat object. With the method it is possible to vary the distance between the flat object and the inductor device and thus the temperature distribution over the transverse profile of the flat object so that the flat object is heated homogeneously.

Abstract: The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

Abstract: A device (1) for inductive heating of a workpiece (2) in a rolling mill, the device (1) including: a converter (3) for creating an alternating voltage, a capacitor bank (6) electrically connected to the converter (3), and having a plurality of capacitors (7) connected in parallel, a working field (8), in which an upper coil (10) and a lower coil (11) are arranged. The workpiece (2) is able to be passed between the coils (10, 11) and is thereby inductively heated by cross-field heating. A housing (4) arranged next to, below or above the working field (8). The converter (3) and capacitor bank (6) are arranged in the housing (4). The coils (10, 11) are each electrically connected to the capacitor bank (6) by a flexible cable (12, 13). The cable (12, 13) is a coaxial cable (27), with one phase of the alternating voltage applied to an inner conductor (28) and the other phase of the alternating voltage applied to an outer conductor (29) of the coaxial cable (27).

Abstract: The invention relates to a process for preparing a pigmented curable molding compound comprising mixing together an unsaturated polyester resin, a thermoplastic polymer, a color paste and optionally a filler, and is characterized in that the color paste is obtained by dissolving pigment particles in a solution of a thermoplastic polymer in a suitable solvent. The invention further relates to the color paste itself and to homogeneously and uniformly colored moldings obtained thereform.

Abstract: A conductor bar and a method for producing a conductor bar of a stator winding for an electric machine, in particular a generator, having a stator as well as a rotor disposed rotatably therein. Each conductor bar is formed of component conductors which are made from conductive material, are situated one above another in pairs, traverse a stack from a top layer obliquely to a bottom layer and each have uniform cranks in the vicinity of the top layer and in a bottom region. The cranks of each two component conductors placed one above another and assigned to one another in pairs are disposed offset in the longitudinal direction at a spacing relative to cranks of a succeeding or preceding pair of component conductor bars. The component conductors are disposed in two stacks located next to one another and laterally adjoining one another. The component conductors are each situated one above another in pairs and are each mutually interlocked through the use of the laterally neighboring component conductors.

Abstract: The invention relates to a process for preparing a conductive curable moulding compound with reduced electrical surface resistance, comprising mixing together an unsaturated polyester resin, a thermoplastic polymer, a conductive paste and optionally a filler, and is characterized in that the conductive paste is obtained by dispersing conductive pigment particles in a solution of a thermoplastic polymer in a suitable solvent. The invention further relates to the conductive paste itself and to mouldings having reduced surface resistance, obtained therefrom.
