摘要: A device for automatic thickness control of rolled strips which ensures an accuracy of the rolled material from + OR - 0.002 mm to + OR - 0.003 mm, does not call for major capital expenses and long stops of the rolling mills for its introduction and is characterized by high operating reliability and simple servicing. The device for automatic thickness control of rolled strips in installations for the manufacture of strip materials, comprising symmetrically located on both sides of the roll stand at least one hydraulic power cylinder installed between the supports of the working rolls, a damping hydraulic cylinder whose piston is fixed while the strip is passing through the roll stand, and a controllable valve connected so that the hydraulic system formed by said hydraulic cylinder and valve is closed and creates a local increase in the rigidity of the roll stand within the range of forces which is approximately equal to the range of variations of the rolling pressure from the preset value. The device has a positive feedback circuit actuated by the fluid pressure in the closed hydraulic system, this circuit comprising a pressure meter in the hydraulic power cylinder, an element for comparing the measured deviation of pressure with the value proportional to the preset coefficient of positive feedback, connected with the pressure meter, and an actuating element connected to said comparison element and to the correcting element made in the form of a hydraulic cylinder communicating with the hydraulic power cylinder.
