Embodiment Construction
[0025] An uncoiler tension building control system provided by an embodiment of the present invention includes a micro-tension coefficient module, a micro-tension calculation module, a motor torque limiting value module, and a control module;
[0026] Among them, the micro-tension coefficient module is used to determine the micro-tension coefficient according to the strip thickness;
[0027] The micro-tension calculation module is used to calculate the micro-tension value according to the micro-tension coefficient and the tension setting value, wherein the range of the tension setting value is 0-40kN;
[0028] The motor torque limit value module is used to calculate the uncoiler motor torque limit value according to the micro tension value and the actual value of the outer diameter of the steel coil on the uncoiler;
[0029] The control module is used for controlling the motor torque of the uncoiler according to the motor torque limit value of the uncoiler.

Abstract
The invention discloses a tension-establishing control system of an uncoiling machine and a method of the tension-establishing control system, and belongs to the technical field of rolling of cold-rolled strips. The system comprises a micro-tension coefficient module, a micro-tension calculation module, a motor-torque amplitude-limiting-value module and a control module, wherein the micro-tension coefficient module is used for determining a micro-tension coefficient according to the thickness of strip steel; the micro-tension calculation module is used for calculating and obtaining a micro-tension value according to the micro-tension coefficient and a tension setting value; the motor-torque amplitude-limiting-value module is used for calculating and obtaining a motor-torque amplitude-limiting value according to the micro-tension value and an actual value of the outer diameter of an upper steel coil of the uncoiling machine; and the control module is used for controlling the motor torque acording to the motor-torque amplitude-limiting value of the uncoiling machine. The tension-establishing control system disclosed by the invention has the advantage that the scratching problem caused by falling of the strip steel when the steel coil penetrates to a coiling machine continuously after being split can be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of cold-rolled strip rolling, and in particular relates to a tension building control system of an uncoiler and a method thereof. Background technique [0002] Before leaving the factory, the automotive sheet products need to trim the edge and cut off the head and tail of the strip that does not meet the specification requirements, conduct quality inspection and oiling on the surface of the strip, and adjust the weight of the steel coil according to the user's requirements. According to this, the recoil inspection unit is set up, equipped with welding machine, disc shear and electrostatic oiler, to inspect, trim, oil and divide the steel coil after leveling. In this way, the strip length running through the recoiling inspection unit is nearly double that of the ordinary recoiling line. The tension of the recoiling inspection unit is jointly provided by the uncoiler and the coiler at the entrance and exit. T...
