  • MASS FLOW REGULATION IN ROLLER DEVICES
    Publication number: 20190039107
    Abstract: A method for controlling a roller line, preferably a cold roller line, which has one or more roller stands each with two working rollers, which form a roller gap, through which a roller band is transportable. One or both working rollers can shift relative to the other, so that the roller gap is adjustable. The method includes making available a reference speed, which is a parameter for controlling the roller line, measurement of speed of the roller band before the inlet into the roller gap, measurement of the thickness of the roller band before the inlet into the roller gap, and adjustment of the roller gap of one or more roller frames in the roller line on the basis of measured speed and thickness before the inlet into the roller gap as well as the reference speed.

  • VOLUME FLOW REGULATING VALVE
    Publication number: 20180345340
    Abstract: A volume flow regulating valve for controlling the volume flow of a fluid medium in two outflow ducts. The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.
