Definitions

  • the present invention relates to a wire rod manufacturing method for manufacturing a wire rod by rolling a material.
  • Patent Documents 1 and 2 When a wire rod is manufactured by rolling a material such as a billet made of steel, for example, the methods described in the following Patent Documents 1 and 2 are known. Specifically, the wire is fed to the spiral guide tube of the rotating wing head while being sandwiched between paired pinch rolls so as to maintain the tension of the wire rolled by the rolling mill, and looped onto the conveyor. Send to. The wire rod is conveyed to a columnar focusing device by a conveyor, and is focused in a coil shape by the focusing device.
  • the rolling drive of the rolling mill, the pinch roll, and the wing head are synchronized in order to run the wire rod at a constant tension without loosening it. Further, when the end of the wire rod passes through the pinch roll, the wing head needs to deliver the wire rod only by the inertial force accompanying the traveling movement of the wire rod and its own rotational force. Further, the rolling speed becomes slower as the size of the material is larger, that is, the diameter of the wire rod to be manufactured is larger.
  • the wire is all sent out from the guide pipe of the lining head. Sometimes it stayed in the guide tube without being used.
  • the material is rolled into a wire rod, and the wire rod is formed on a spiral guide tube of a wing head that rotates at a rotation speed set according to the rolling speed.
  • the wire rod manufacturing method in which the wire rod is wound into a coil shape by feeding and sending the wire rod in a loop shape, when the material is rolled at a rolling speed lower than the reference speed to manufacture the wire rod, the end of the wire rod is terminated.
  • the rolling head is characterized in that the rolling speed of the wing head is increased to be equal to or higher than the rotation speed set according to the reference speed before the wing head enters the guide pipe.
  • the rotation speed of the lining head is used as a reference before the end of the wire rod enters the guide pipe of the lining head. Try to increase the speed so that it exceeds the rotation speed set according to the speed. As a result, the inertial force of the wire rod is increased, and the transmission / output of the wire rod by the wing head is also increased. Therefore, it is possible to ensure that all the wire rods are sent out from the guide tube without staying in the guide tube of the laying head.
  • the wire rod manufacturing apparatus 100 includes a rolling mill 110 that rolls a material 1 such as a billet made of steel into a wire rod 2.
  • the rolling mill 110 includes a plurality of pairs of rolling rolls 111 and 112 in series. Paired pinch rolls 121 and 122 are arranged on the downstream side of the wire rod 2 of the rolling mill 110 in the delivery direction.
  • a wing head 130 that feeds the wire rods 2 in a loop shape is arranged.
  • the laying head 130 includes a spiral guide tube (not shown), and by rotating, the wire rod 2 fed to the base end side of the guide tube is sent out in a loop shape from the tip end side of the guide tube. You can do it.
  • the upstream side of the conveyor 140 which conveys the wire 2 in a loop shape, is in contact with the downstream side of the wire 2 of the lining head 130 in the delivery direction.
  • a columnar focusing device 150 for concentrating the wire rod 2 from the conveyor 140 in a coil shape is arranged on the downstream side of the conveyor 140 in the transport direction.
  • 101 is a hot mass detector (HMD).
  • the HMD 101 is arranged near the receiving port of the material 1 of the rolling mill 110 so that it can detect that the end of the material 1 has passed.
  • the material 1 is fed to the rolling mill 110, rolled to the desired diameter size by the rolling rolls 111 and 112, and sent out as the wire rod 2.
  • the pinch rolls 121 and 122 feed the wire rod 2 to the base end side of the guide pipe of the rotating wing head 130 while maintaining the tension of the wire rod 2 sent out from the rolling mill 110.
  • the lining head 130 sends the wire rod 2 fed into the guide pipe from the tip side onto the conveyor 140 in a loop shape.
  • the conveyor 140 conveys the wire rod 2 to the focusing device 150 in a loop shape and delivers it.
  • the focusing device 150 winds the wire rod 2 into a coil and focuses it. As a result, the wire rod 2 having the desired diameter size can be obtained from the material 1.
  • the rotation speed of the lining head 130 is set according to the rolling speed of the rolling mill 110. As the rolling speed increases, the length of the wire rod fed to the lining head 130 and sent out from the lining head 130 per unit time becomes longer. Therefore, if the rotation speed of the lining head is the same, the diameter of the loop of the wire rod formed by the lining head 130 becomes large.
  • the diameter of the loop is substantially equal to the diameter of the wire coil formed by focusing by the focusing device 150. Since the coil diameter to be manufactured is predetermined, when the rolling speed is high, the operation of increasing the rotation speed of the lining head 130 is performed. That is, the rotation speed of the lining head 130 is set according to the rolling speed.
  • the rolling speed of the rolling mill 110 generally becomes slower as the diameter of the wire after rolling becomes larger.
  • the rolling speed of the rolling mill 110 means the speed of the wire rod on the exit side of the rolling rolls 111 and 112 at the most downstream side of the rolling mill 110, which is the feeding speed of the wire rod to the lining head 130. ..
  • the feeding speed and diameter of the rolling material to the rolling mill 110 are constant, the smaller the diameter of the wire after rolling, that is, This is because the larger the surface reduction rate due to rolling, the higher the speed of the wire rod on the exit side of the rolling mill.
  • the wire rod manufacturing apparatus 100 detects the end of the material 1 when the HMD 101 detects the end of the material 1. Based on, do as follows. That is, the wire rod manufacturing apparatus 100 increases the rotational speed of the laying head 130 so that the end of the wire rod 2 becomes equal to or higher than the reference speed Vs immediately before entering the guide pipe of the lining head 130.
  • the lining head 130 needs to send out the wire rod 2 only by the inertial force accompanying the traveling movement of the wire rod 2 and its own rotational force. For this reason, conventionally, when the rolling speed (running speed) is slow and the rotation speed of the wing head is slow, after the end of the wire 2 passes through the pinch roll, the wire 2 is all sent out from the spiral guide tube of the lining head. Sometimes it stayed in the guide tube without being used.
  • the wire rod 2 when the rolling speed (running speed) is slow and less than the reference speed Vs, that is, the wire rod 2 may not be completely delivered from the guide pipe of the laying head 130 and may stay in the guide pipe. If there is, the above method is used. That is, the rotation speed of the lining head 130 is increased so that the end of the wire rod 2 becomes equal to or higher than the reference speed Vs immediately before entering the guide tube of the wing head 130.
  • the reference speed Vs includes various types of the wire rod manufacturing apparatus 100, such as the length of the guide pipe of the wing head 130, the diameter size of the spiral shape, the length between the rolling mill 110 and the pinch rolls 121, 122 and the wing head 130, and the like. It is a value that can be set for each manufacturing apparatus by conducting an experiment based on the original.
  • the rotation speed of the lining head 130 is increased so that the end of the wire 2 becomes equal to or higher than the reference speed Vs immediately before entering the guide tube of the wing head 130, but the timing for increasing the rotation speed is set. It does not have to be immediately before, as long as the end of the wire 2 is before entering the guide pipe of the wing head 130.
  • the wire rod manufacturing apparatus 100 runs the wire rod 2 with a constant tension without loosening, so that the rolling mill 110
  • the rolling speed, the peripheral speeds of the pinch rolls 121 and 122, and the rotational drive of the lining head 130 are synchronized.
  • the rotation speed is synchronized with this.
  • the rolling speed and the peripheral speed of the pinch roll are also increased.
  • the rolling speed and the peripheral speed of the pinch roll are increased in synchronization with the rotation speed of the lining head 130, so that the traveling speed of the end of the wire 2 is also increased.
  • the approach speed of the rolling head 130 to the guide tube is also increased. Therefore, the effect of preventing the end of the wire rod 2 from staying in the guide tube becomes greater.
  • the rolling speed of the rolling rolls 111 and 112 may be increased during rolling, which may lead to deterioration of the quality of the wire rod 2.
  • the portion of the wire rod 2 rolled by increasing the rolling speed of the rolling rolls 111 and 112 is not so long and is not much different from the length cut by normal trimming, so that it can be removed by trimming. , No particular problem arises. If the rotation speed of the lining head 130 is to be increased at the time when the end of the wire 2 is between the rolling mill 110 and the pinch rolls 121 and 122, the peripheral speed of the pinch rolls 121 and 122 is used to rotate the lining head 130. You just have to synchronize with the speed and speed up. Even in this case, the traveling speed at the end of the wire 2 and the approach speed at the end of the wire 2 to the guide pipe can be increased.
  • the traveling speed of the wire rod 2 may not increase as expected.
  • the pinch rolls 121 and 122 are located closer to the lining head 130 than the rolling mill 110, depending on the distance between the pinch rolls 121 and 122 and the lining head 130, the pinch rolls 121 and 122 may be used as the guide pipe of the lining head 130. It is possible that the time required for the end of the wire 2 to reach is short, and sufficient time for accelerating the end of the wire 2 cannot be secured.
  • the rolling mill 110 and the pinch Since both the rolls 121 and 122 serve as drive sources for increasing the traveling speed of the wire rod 2, the traveling speed at the end of the wire rod 2 can be surely increased. Further, the rolling mill 110 is upstream of the pinch rolls 121 and 122.
  • the speed of the rolling mill and the pinch roll is increased when the end of the wire 2 does not pass through the rolling mill 110, the time until the end of the wire 2 reaches the laying head 130, that is, Since the acceleration time can be secured longer, the rotation speed of the rolling head at the time of entering the guide pipe at the end of the wire 2 and the approach speed of the end of the wire 2 to the guide pipe can be made faster. Therefore, when the end of the wire rod 2 does not pass through the rolling mill 110, it is preferable to increase the rolling speed and the peripheral speed of the pinch roll in synchronization with the rotation speed of the lining head 130.
  • the present invention is not limited to this.
  • the HMD 101 is arranged in the vicinity of the receiving port of the material 1 of the rolling mill 110 so that the passage of the end of the material 1 can be detected.
  • the invention is not limited to this.
  • the HMD 101 is arranged between the rolling mill 110 and the pinch rolls 121 and 122 so that it can be detected that the end of the wire rod 2 has passed. It is also possible to do.
  • the timing for increasing the rotation speed of the lining head 130 is determined based on various manufacturing conditions such as the sizes of the material 1 and the wire rod 2 and the rolling speed by omitting the detection means such as the HMD 101. It is also possible to request it in advance and respond to it.
  • the wire rod manufacturing method according to the present invention can be used extremely beneficially in the steel industry and the like because all the wire rods can be sent out from the guide pipe of the wing head even when the wire rod having a large diameter is manufactured. can.
