Definitions

  • the invention relates to a cold rolling mill and to a method of cold rolling metal strip, especially steel strip, with a single-frame rolling mill with means for adjusting a rolling gap and a coiler device upstream of the cold rolling mill frame for uncoiling the strip fed to the mill.
  • a Steckel rolling mill for hot rolling, having at least one reversible rolling mill frame as well as coilers disposed upstream and downstream thereof. Between the coilers and the reversing mill frame, respective loop lifters are provided which supply actual values for a tension control and a mass flow control.
  • Such a Steckel rolling mill relates to hot rolling mills and, therefore, not to any cold rolling process.
  • the invention has as its object to provide a method of cold rolling as well as a cold rolling mill with a single-frame mill and which in spite of changes in the strip thickness and large strip speeds does not have any problems with respect to the mass flow and/or the strip tension.
  • a strip storage is disposed for a mass flow regulation and/or a stripper tension regulation of the rolling process, especially in the case of flexible rolling.
  • each of the strip storages has a dancer roller.
  • a dancer roller or a dancer roller arrangement includes a roller which is pressed with a certain force against the strip and which is adjustable within a certain angle so that a loop is formed in the strip around the dancer roller and such that the loop length varies with the position of the roller. In this manner more or less of the strip can be stored.
  • a respective dancer roller is provided both at the inlet and at the outlet regions of the single mill frame and both are advantageously of identical construction.
  • FIG. 1 a layout of an apparatus of an embodiment of a cold rolling frame according to the invention with flexible cold rolling with respective dancer rollers at the inlet and outlet regions;
  • FIG. 2 a detailed elevation of the dancer roller as well as a preferred embodiment of its positioning and control;
  • FIG. 3 an overview of the strip tension and mass flow control circuits with flexible cold rolling using a single frame mill
  • FIG. 4 an overview of the strip thickness control circuit in combination with the strip tension control as well as a compensation of the mass flow faults with flexible cold rolling with a single frame mill.
  • FIG. 1 provides an overall view of an apparatus having a single frame cold rolling mill 1 with strip storage 2 , 3 at both the inlet region ( 4 ) and the outlet region ( 5 ) of the single frame mill 1 and each of which encompasses a dancer roller 6 , 7 .
  • the coiled up strip 8 is uncoiled with the aid of a coiling device 9 and is fed into the rolling frame 1 in the direction of the arrow. After traversing the single frame mill 1 , the strip is coiled up by means of a second coiler 10 .
  • a respective dancer roller 6 , 7 is provided, the dancer coilers being of identical construction and have been illustrated in detail in FIG.
  • the single frame mill 1 itself is comprised, in the illustrated embodiment, of two backup rolls 11 , two intermediate rolls 12 and the working rolls 13 , 14 . Any other arrangement of rolls in a single frame can also be used. Between the roll frame 1 and the dancer rolls 6 , 7 , for example at the outlet side 5 , a marking device 15 can be arranged in the strip line.
  • FIG. 2 shows the mechanism and control of a dancer roller 6 with a flexible cold rolling.
  • a loop is formed inteh striper 8 with a loop length which changes with the position of the dancer roller 6 or its angular setting with respect to the roller 16 .
  • the deeper the dancer roller 6 penetrates into the strip 8 the more of the strip which is stored.
  • the illustrated embodiment shows a hydraulic adjustment 18 for the dancer roller 6 .
  • the dancer roller 6 is associated with a force controller 19 .
  • a force controller 19 For this control, an actual force value as well as an actual angle value of the positioning of the dancer roller 6 are obtained.
  • This actual force value is supplied to the force controller 19 together with a force setpoint value.
  • the force setpoint value is not predetermined but rather is calculated from the measured actual angle value and a predetermined setpoint tension.
  • the force control circuit provides, as a result of the comparison of the setpoint and actual force values, a force correction value which is applied to the positioning unit 18 , here a hydraulic piston and cylinder unit for the dancer roller 6 . By means of the force correction, a correction of the tension developed by the strip in traction is achieved.
  • the actual angle value measured at the dancer roller is also used for the control of the rotary speed setting of the coiler devices ( 9 , 10 ) and thus torque control of the coilers for mass flow control.
  • the actual angle value as well as a predetermined setpoint angle are fed to an angle controller.
  • an angle correction value is calculated. This angle correction value serves for control of the speed in the coiler devices for mass flow control.
  • FIG. 3 An overview of this strip tension control and mass flow control by means of the dancer rollers 6 , 7 at the inlet and outlet regions ( 4 , 5 ) of a cold rolling frame 1 has been shown in FIG. 3.
  • the strip tension control is effected by calculating a setpoint force for controlling the hydraulic setting of the dancer roller, starting from the actual force value while the mass flow control results from control of the speed of the coilers.
  • the setpoint value is the strip speed. This also serves as a setpoint for the roll speed control.
  • a flexible rolling process means that there will be a change in the rolling gap in the course of rolling and thus an valuation in strip thickness patterns over the strip length.
  • a setpoint strip thickness pattern is predetermined. This setpoint value of the course of the strip thickness is used for initial control of the inlet side dancer roller. From the setpoint course of the strip thickness, the change in the inlet speed of the strip in the rolling mill frame is calculated together with the strip tension required for it to maintain a constant strip tension. For mass flow compensation, the inlet tension can be further smoothed out.
  • values of the setpoint strip thickness course can be supplied to a thickness controller which with the aid of actual strip thickness values obtained at the inlet and outlet side, corrections and values for the strip thickness can be calculated, these correction values further supplied to a position controller which controls the rolling gap setting in the cold rolling frame.
