  • Patent number: 11040385
    Abstract: A cooling section for flat rolling stock has a working region, through which the flat rolling stock is guided. The working region can be supplied with a liquid coolant by means of a number of spray beams. The liquid coolant is fed from a reservoir for the liquid coolant to the spray beams by means of a pump and a supply system. Valves are arranged upstream of the spray beams in the supply system. Opening positions of the valves are set by a control unit of the cooling section according to a respective sub-flow that is to be applied to the flat rolling stock by means of each spray beam. Also, the delivery rate of the pump and/or a line pressure generated by the pump in the supply system are set by the control unit according to the total flow that is to be applied to the flat rolling stock by means of all the spray beams.

  • Patent number: 9878358
    Abstract: A cooling section for a flat rolled material (1) has a frame structure (2), in which a plurality of transport rollers (3) for the flat rolled material (1) are arranged one after another transversely to a transport direction (x) and spaced apart (a). Each transport roller (3) mounted in the frame structure (2) rotates about a respective roller axis (4). The roller axes (4) run orthogonally to the transport direction (x) and horizontally, so that the transport rollers (4) form a pass line (5) for the flat rolled material (1). At least one lower spray bar (6) arranged beneath the pass line (5) has a base block (7) beneath the transport rollers (3) for a liquid coolant (8). Guide sections (9) project upwards from the base block (7) into spaces between the transport rollers (3). Each guide section (9) has an upper terminating element (10) on which spray nozzles (11) are arranged, which feed the coolant (8), which had been fed into the base block (7), to be sprayed onto the flat rolled material (1) from below.

  • Patent number: 9868142
    Abstract: A flat rolled article (2) passes through a cooling device (1) in a transportation direction (x) at the level of a passline (3). Spray bars (5, 6) extend transversely with respect to the transportation direction (x). The spray bars (5, 6) have, as viewed perpendicular to the transportation direction (x), in each case two outer regions (7, 8) and a central region (9) in between. A liquid cooling medium (13) can be fed into the regions (7, 8, 9) via respective dedicated, individually controllable valve devices (10, 11, 12). Flow rate profiles, pertaining to each region may be set, wherein each region (7, 8, 9) is triangular in shape. The central triangle and the two outer triangles combine to form a rectangle.

  • Patent number: 8950227
    Abstract: A method and a device have high energy efficiency and high descaling performance, with which high-quality rolling stock can be produced. In a method in which the rolling stock is heated in an induction furnace and subsequently descaled, before the rolling stock is rolled in a rolling stand or rolling relay, the heated rolling stock is descaled by at least one rotating water jet from a rotary descaler; then at least one temperature of the descaled rolling stock is respectively recorded by a temperature measuring instrument and delivered to a controller; and the controller determines at least one control parameter with the aid of a control rule and by taking into account a setpoint temperature, and delivers it to a control component, at least one inductor of the induction furnace being driven so that the temperature of the descaled rolling stock corresponds as far as possible to the setpoint temperature.
