摘要： PURPOSE:To improve detection accuracy and sensitivity by providing magnetical shield bodies on core side faces and maintaining the distance between the shield bodies and the cores at more than twice the distance from the cores up to the steel plate to be detected of its shape. CONSTITUTION:This device obtains the flatness of a rolled steel plate by making use of the fact that there is a fixed proportional relation between the magnetic permeability and internal stress of the rolled steel plate, wherein the detector comprises combining two laminated U-form cores 7, 8 at a right angle, providing an excitation coil 1 at the contact point of the magnets thereof and simultaneously providing pressure detecting coils 2, 3 and gap detecting coils 4, 5. Magnetic shield plates 15 composed of magnetic material are provided near the side faces of the respective detectors constituted in this way so that the leaking magnetic flux emitting from the primary coil 1 is made difficult to reach the other detector. In addition, these are so constituted that the distance B from the shield plates 15 up to the core 8 is maintained more than twice the distance lg between the core 8 and the steel plate 6.

摘要： PURPOSE:To control a pattern of an exciting current to a solenoid coil by a controller on the basis of comparison of a detected speed value with a target speed value, by detecting the actual transfer speed of a steel pipe with a detector. CONSTITUTION:In case of presetting a transfer speed of a steel pipe to within a range of 0.05-0.1m/sec, if an actual transfer speed increases exceeding this range, the speed is detected by a detector 24 to obtain a difference from a target speed value in a speed converter 25, on the basis of this compared signal, a controller 16 decreases a negtive feedback quantity to a power source side to increase an exciting current to solenoid coils 11 and perform brake control to a decreasing direction unitl the transfer speed reaches the target speed value. On the contrary, when the transfer speed decreases to not within said range by said electromagnetic brake, on the basis of then compared signal, the controller 16 inverts the operating direction of a thyristor 15 to demagnetize residual magnetism of the steel pipe by a prescribed reverse current and automatically release the electromagnetic brake.

摘要： PURPOSE: To intensify suction force for ensuring tansfer of steel pipes in a device for transferring the steel pipes on an inclined rail with magnetic suction by providing two magnetizing coils in identical magnetic poles.
CONSTITUTION: Two magnetizing coils 11a, 11b are arranged in main magnetic poles 12a disposed on a magnetic frame 13 to intensify magnetomotive force for a steel pipe transferring device. The upper surface of the magnetic pole 12 is slanted to a skid rail 1 so that steel pipes 10 are transferred from point A to point B by sequentially changing over magnetization while being sucked magnetically. Thus, while power consumption is doubled by disposing two magnetizing coils, magnetic suction is intensified by 7 times. Further, auxiliary magnetic poles 12b are arranged at both sides to supplement the suction force.

摘要： PURPOSE:To reduce the noise produced at the time of collision in such a manner as control the initial velocity, by a method wherein, in a magnetic skid rail which rolls steel pipes along a slope as it brakes them, a braking force produed in proximity of a delivery end is generated more powerful than that at the other portion. CONSTITUTION:A magnetic skid rail 5 tilts at a suitable angle from a delivery side to a despatch side, and steel pipes delivered thereonto from a roller conveyor 3 through the working of a kicker are stored on the skid rail. An outer magnetic pole 6b positioned in proximity of a magnetic rail delivery end is made larger than outer magnetic poles at the other portion so that a rolling speed of the steel pipe thereat can be decelerated. This causes the steel pipes delivered onto the skid to be transferred at a sharply reduced speed of collision with the steel pipes stored. The collision noise can thus be decreased.
