摘要： PURPOSE:To measure stress distributions in the width direction of a belt-like magnetic material instantaneously by dividing magnetostrictive sensors to two groups, and moving the respective groups in the width direction in conformity with the respective end part positions in the direction of the belt-like magnetic material. CONSTITUTION:The 1st magnetostrictive sensor group 42 and the 2nd magnetostrictive sensor group 44 consisting of plural pieces of L-shaped magnetostrictive sensors 40 are so arranged as to be moved in the width direction by means of a positioning cylinder. The sensors 42, 44 are so disposed that the respective sensors 40 are located specularly symmetrically with respect to the centerline C of a rolled steel plate 18, whereby the stress detecting positions of the groups 42, 44 are made symmetrical on the right and left. When tension acts in the rolling direction, differences are generated in the voltage detected by the coils 66, 68 in the respective directions, and from these voltage differnces, the stress distributions of the plate 18 are determined.

摘要： PURPOSE:To reliably determine the degree of configuration defect, by a method wherein configuration is evaluated by employing a detected stress signal as it is or an absolute stress obtained by correcting the detected stress signal by an overall tension according to whether the variation of a gap signal is below or above a given value. CONSTITUTION:An excitation coil 14 and detection coils 20, 22 are disposed along the moving direction of a belt-shaped magnetic substance 18 moving at high speed in order to measure the stress applied to the belt-shaped magnetic substance 18 by utilizing magnetostriction effect. In addition, the stress distribution in the width direction of the belt-shaped magnetic substance 18 is made known by detecting the gap between the detector and the belt-shaped magnetic substance 18, and the configuration of the belt- shaped magnetic substance 18 is evaluated from the stress distribution. When the variation of the gap signal is below a given value, i.e., in a state where configuration is latent, the configuration is latent, the configuration is evaluated by employing the detected stress signal as it is. On the other hand, when the vairation of the gap signal is above the given value, i.e., in a state where the configuration is actualized, the configuration is evaluated by employing an absolute stress obtained by correcting the detected stress signal by an overall tension.

摘要： PURPOSE:To increas the crack signal strength by arranging the centers of detecting coils at the inner periphery of an exciting coil, and increasing the magnetic fluxes which are linked with the detecting coils. CONSTITUTION:The centers of the detecting coils 2A1, 2B1,...2A4, and 2B4 are located on the inner periphery of the exciting coil 1. The beginning of the winding of the detecting coil 2A1 is connected to the first signal output terminal, the end of the winding thereof is connected to the end of the winding of the detecting coil 2B1, and the beginning of the winding of the detecting coil 2B1 is grounded. Likewise, the detecting coils 2A2, 2B2,...2A4, and 2B4 are connected, and the second signal output terinal - the fourth signal output terinal are obtained. The exciting coil 1 is excited by a high frequency power source, and each signal output terminal is sequentially detected. Thus, the cracks at the position of the detecting coils 2A1, 2B1,... 2A4, and 2B4 can be detected. In this constitution, the strength of the crack signal from the probing coils are increased, and the complex signal processing is unnecessitated.

摘要： PURPOSE:To reduce noise produced at a time when steel pipe is conveyed and to prevent exfoliation of the corrosion-proof agent applied on the steel pipe, by a method wherein the steel pipe is conveyed through the contact of the pipe with a convex part formed on a magnetic rail. CONSTITUTION:A steel pipe 10 applied with a corrosion-proof agent is conveyed onto a skid rail. Said conveyance device consists of an inner pole core 3 including the skid rail, an excitation coil 4 rolled around the inner pole core 3, a pair of outer pole cores 6, which include skid rails located in parallel with each other at both sides of an inner pole magnetic rail 5 connected to the inner pole core 3, and a magnetic frame 1 which connects together said inner pole core 3 and the one end each of the outer pole cores 6 positioned facing and opposite to the skid rail. Convex parts 15a, whose widths are narrower than that of a magnetic rail 15, are provided on the magnetic rail 15 serving as the skid rail, and this causes the reduction in a surface area where the magnetic rail makes contact with the steel pipe 10. As a result, a noise generated at a time when the steel pipe 10 is conveyed can be reduced, and exfoliation of the corrosion-proof agent applied on the steel pipe 10 can be prevented.

摘要： PURPOSE:To reduce the noise when loading steel tubes by successively changing position of the end of the transfer system so as steel tubes bump at ends one after the other. CONSTITUTION:The steel tube 25 is brought in by the kicker 24, and rolls over the skid-rail 11, and subsequently transferred to the cradle 30 by the transfer skid 15. And when the transfer skid 15 is coming back to the original position leaving the steel tube 25 on the cradle 30, the end of the steel tube on the side of the transfer skid 15A drops on the cradle 30 as the end of transfer skids 5A-15C is installed with a difference of dimension of 1 respectively. In this instance, regardless of some large distance for the steel tube 25 falling down, bumping sound is small as it bumps only at an end. And, the steel tube is gradually loaded on the cradle 30, being moved from the position of 15B to the transfer skid 15C, thereby remarkably reducing the bumping sound.
