摘要： PURPOSE:To detect easily and exactly the position of a weld zone with good reproducibility by making an ultrasonic pulse incident from an oscillator for transmission to a welding steel pipe, propagating the pulse along the weld line and detecting the change in the level of the transmitted pulse with an oscillator for reception. CONSTITUTION:A weld zone 2 of an electric welded steel pipe 1 subjected to high frequency resistance welding forms a linear weld line along the axial direction of the pipe and is subjected to an annealing treatment and bead cutting after welding. An oscillator set 5 rotating in a circumferential direction relatively with the pipe 1 is provided on the outside circumference of the pipe, and an ultrasonic pulse for scanning is emitted from an oscillator 5 for transmission of said set and is made incident and propagated in parallel with the weld line. Said pulse repeats reflection on the inside and outside pipe wall surfaces 1A, 1B of the pipe 1, and generates a large change in the pulse level in the weld zone 2 where the parallelism between the pipe walls is disturbed. Such pulse is detected with an oscillator 4 for reception whereby the position of the weld zone 2 is easily detected.

摘要： PURPOSE:To measure efficiently the surface ruggedness in an optional position without sampling a billet by placing a rail on the billet and running freely a measuring truck, where a contact displacement meter connected through a shaft mechanism is mounted, on this rail. CONSTITUTION:A rail 1 is placed on the upper face of a billet 10, and a free running truck 2 is placed on the rail 1. The first shaft 3a is attached pivotally to the upper face of the truck 2 rotatably at right angles to the direction of truck movement. The second shaft 3b is attached pivotally to the end part of the shaft 3a at right angles to the shaft 3a. A contact displacement meter 4 is attached pivotally to the end part of the shaft 3b. When the surface ruggedness of the upper face of the billet 10 is measured, the shaft 3b is made approximately horizontal to bring the tip of a contact needle 5 into contact with the upper face of the billet. At this time, the contact needle 5 is inclined at 10-30 deg. to the perpendicular of the face to be measured in the direction of truck movement.

摘要： PURPOSE:To obtain the stable amplitude of a mold and to stabilize operation by detecting the change in the temp. of the mold according to operating conditions as a change in an oscillating acceleration and controlling the frequency for ultrasonic oscillation. CONSTITUTION:The change in the temp. of an ultrasonically oscillated mold 20 is detected as a signal for the change in an oscillating acceleration by using an acceleration sensor 10. The signal is inputted to a frequency tracking circuit 11. An oscillating frequency is so selected that the change in said acceleration attains a max. value. Said frequency is then outputted to an ultrasonic oscillator 21 or the impedance of an exciter and the oscillator 21 are matched by changing the capacity of a capacitor. The oscillating frequency is thus controlled according to the operating conditions of the mold for continuous casting and the operation is stabilized.

摘要： PURPOSE:To improve the reliability and to make the device small-sized, simple, and low-cost, by propagating ultrasonic pulses along a weld line and providing a weld position detecting device on a common base coaxially. CONSTITUTION:A transmitting oscillator 3 and a receiving oscillator 4 are provided along the weld line of a weld 2 so as to face each other, and the ultrasonic beam radiated from the transmitting oscillator 3 is made incident to a welded steel pipe 1 at a prescribed angle and is propagated along the weld line while being reflected prescribed-number of times repeatedly on inside and outside tube walls 1A and 1B and is received by the receiving oscillator 4. Since the variance of the level of transmission pulses in the weld reaches about >=20dB which is >=10 times as high as that in a base material part 8 where there are no variance of thickness, defects, etc., the position of the weld is detected accurately. Since a weld position detecting device 20 is provided on a common base 50, displacement parallel with the axis of an electric welded steel pipe 1 corresponds to devices 20 and 40 in 1:1, and copying control of a flaw detector 40 is performed directly with a weld position signal, which the weld position detecting device 20 detects, for displacement around the axis of the pipe.

摘要： PURPOSE: To discriminate a slag metal inexpensively with good workability by providing an electromagnetic oscillation detector to an attaching and detaching device for a charging nozzle of a vessel for molten metal and detecting the decrease in the fluctuation value of the specific frequency of the detected signal thereof as the point where the passage of the slag starts.
CONSTITUTION: An electromagnetic oscillation detector 8 is disposed without contacting to an attaching and detaching device 2 for a nozzle 2 which charges the molten steel in a ladle 1 into a tundish 3. The oscillation signal which is detected with the detector 8 is amplified 9 and is differentiated twice with differentiation circuits 10, 11. The outputs thereof are passed through a band-pass filter 12 which allows the passage of only the specific frequency band. The above-described signal past the filter 12 is inputted to a half-wave or full-wave rectifier circuit 13, by which the signal is converted to the signal that bases on an output voltage with zero V. Said signal is further passed through a low-pass filter 14 and a half-wave or full-wave rectifier circuit 15 and is further passed through a low-pass filter 16, from which an envelope is drawn out. On the other hand, the signal output set with a frequency is inputted to a comparator 10, by which the output is compared and calculated with the set signal of a setter 18 and the outflow of the slag is detected when the signal level of the filter 16 attains a specified value or below. An alarm device 19 is then operated.

摘要： PURPOSE:To obtain an ingot having uniform quality without giving any abnormal fluctuation in stress to the ingot, by detecting the fluctuation in the displacement of support rolls for the ingot, etc. and correcting the bending of the rolls in the direction where the rate and period of bending of the rolls are made uniform. CONSTITUTION:Displacement meters 1, 2 for the rear surfaces of support rolls 8, 9 for an ingot of a continuous casting machine which detect the bending of said rolls, load cells 4, 5, 6, 7 which measure the reaction in roll chock parts, a displacement meter 3 between the roll chocks which measures the fluctuation in the gap between the roll chocks, and a target 3' thereof, etc. are provided to detect the fluctuation in stress, the fluctuation in displacememnt or the rate relating to these fluctuations owing to the bending of the rolls. When the detected values exceed set values, cooling water is sprayed from cooling water headers 12, 13 for correcting upper and lower rolls to the projecting parts of the rolls 8, 9 during the time when the recesses of said rolls are in contact with the ingot 14 under drawing. The bending of the rolls is thus corrected and the gap between the rolls in the axial direction of the rolls is made roughly constant.

摘要： PURPOSE:To enable flaw discrimination, whether it is produced before produced rolling process or is produced during the rolling process, by installing an eddy current flaw detecting devices at the inlet and the outlet of the rolling mill. CONSTITUTION:A piercing type eddy current detecting coil 13 for finding a flaw of a wire material is usually of a cassette type and is incorporated in a coil holder 14. An eccentric rotary type calibrator 18 is adjusted to a position where a center of a sample 4 and the center of the coil 13 are brought to an eccentric relation to each other, a rotation of the sample 4 takes place to make a correction, and this enables completing of a correction in a very short time. After a correction is completed, the coil holder 14 returns along a guide 17 and is located to its original position. Meanwhile, detecting signals from detecting coils 13, 13 situated before and after a finishing rolling mill 12 are inputted to a processor 15, a flaw signal is fetched to decide the presence and a state of a flaw, and the result is displayed by a display unit 16. This permits the flaw discrimination, whether it is produced before rolling process or is produced during the rolling process.
