Definitions

  • the present invention relates to a coiling apparatus.
  • the coiling process in the hot rolling line will be described. As the wire passes through the pair of pinch rolls, the leading end of the strip bends downward. The tip of the bend strip then wraps around the mandrel between the mandrel and the wrapper roll surrounding it. After a certain period of time has elapsed, the mandrel expands outwardly in the circumference and coil tension is applied between the pinch roll and the mandrel.
  • a coiling apparatus that allows a steel sheet entering a coil in a hot rolling line to be wound well in a coiler mandrel.
  • a coiling apparatus comprising: a pinch roll unit having an upper pinch roll for bending a steel plate; A coil ring model calculator for calculating a moving distance and moving the position of the upper pinch roll along the moving direction of the steel plate, a position controller for moving the upper and lower positions of the upper pinch roll according to the calculated value of the coil ring model calculator, And a coil portion for coiling the steel sheet bent by the pinch roll portion.
  • a desirable bending shape can be obtained, and the coiling quality is stabilized.
  • FIG. 1 is a schematic configuration diagram of a coiling apparatus according to an embodiment of the present invention.
  • FIG. 2 is a flow chart schematically showing the operation of the coiling apparatus according to an embodiment of the present invention.
  • FIG. 1 is a schematic configuration diagram of a coiling apparatus according to an embodiment of the present invention.
  • a coiling apparatus 100 includes a coil ring model calculator 110, a position controller 120, a pinch roll unit 130, and a coiler unit 140 .
  • the coil ring model calculator 110 can control the bending of the steel sheet s by calculating the load and the moving distance of the upper pinch roll 132 of the pinch roll part 130 according to the material information of the steel sheet s.
  • the material information of the steel sheet s may be at least one of the thickness, the steel grade, and the initial shape of the steel sheet s.
  • the position controller 120 can control the position of the upper pinch roll of the pinch roll part 130 according to the calculation value of the coil ring model calculator 110.
  • the pinch roll part 130 may include an upper pinch roll 132 and a lower pinch roll 133 inside the housing 131.
  • the upper pinch roll 132 and the lower pinch roll 133 may be included in separate housings.
  • the steel sheet s introduced between the upper pinch rolls 132 and the lower pinch rolls 133 can be bent due to the rotation operation of the upper pinch rolls 132 and the lower pinch rolls 133.
  • the pinch roll portion 130 may include a position-moving cylinder 134, a vertically-moving cylinder 135, and a hinged block 136.
  • the upper and lower moving cylinders 135 can move the upper pinch rolls 132 in a direction perpendicular to the moving direction of the steel sheet s It can be moved in one vertical direction.
  • the coil unit 140 may include a mandrel 141 and a unit roll 142 to coil the bent steel sheet s.
  • FIG. 2 is a flow chart schematically showing the operation of the coiling apparatus according to an embodiment of the present invention.
  • the coil ring model calculator 110 acquires material information, such as thickness, steel grade, and initial shape, of the steel sheet when the steel sheet s enters the pinch roll portion 130,
  • material information such as thickness, steel grade, and initial shape
  • the pressure of the upper pinch roll 132 forming the bending of the material and the amount of movement of the upper pinch roll in the advancing direction of the steel sheet can be calculated (S10).
  • the coil ring model calculator 110 adjusts the bending of the steel plate by the following model formula.
  • T is the thickness of the steel sheet
  • w is the width of the steel sheet
  • sigma strip is the yield strength of the steel sheet
  • D is the yield strength of the steel sheet
  • D is the tensile strength of the mandrel of the coil section
  • Diameter is the thickness of the steel sheet
  • the load and the moving distance of the upper pinch roll for each material of the steel sheet are calculated by using the calculated values. Based on this value, the position-moving cylinder 134 performs movement control in the advancing direction of the steel sheet s, (132) is moved in the advancing direction of the steel sheet (s).
  • the position shifting cylinder 134 is installed in the housing 131 and fixes the upper pinch roll 132, it is possible to absorb the impact at the time of entering the steel plate.
  • the position shifting cylinder 134 is mounted on the inlet side and the outlet side of the upper pinch roll 132, respectively, to fix the housing of the upper pinch roll 132.
  • the hinge type block 136 is provided so that the up-and-down moving cylinder 135 that applies pressure to the upper pinch roll has a rotatable shape.
  • the position controller 120 controls the up-and-down cylinder 135 to move the upper pinch roll 132 in the up-and-down direction with respect to the calculated travel distance in the position-moving cylinder 134 (S20).
  • r denotes an adjustment coefficient
  • S denotes a moving distance of the upper pinch roll
  • G denotes a roll gap of the up-down moving cylinder.
  • the position shifting cylinder 134 and the up-and-down moving cylinder 135 are provided to move the upper pinch roll 132 in two axes so as to control the bending of the steel sheet s to a desired position (S30).
  • a desired bending shape can be obtained by moving the upper pinch roll in the coiling direction from the material information such as the thickness and rigidity of the steel sheet material entering the hot-rolled coiler to adjust the bending,
  • the ring quality can be stabilized.
