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.

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 obtain a sufficient current for detection of flaws and to improve both sensitivity and S/N, by providing ferrite core electrodes to generate 2 pairs of magnetic fluxes to the surface of a material to be checked. CONSTITUTION:A knife edge is formed at the area where ferrite core electrodes 1 and 1' wound with coil windings 2 and 2' face a material 3 to be checked, and the distance between a pair of knife edges is set equal to the minimum distance between a pair of electrodes. As a result, the magnetic fluxes are easily concentrated between knife edges to increase the efficiency. Therefore two units of electrodes are used to generate 2 pairs of magnetic fluxes, and a differential connection is given between the coils 2 and 2'. Then a current is flowed to the coils, and the material 3 is shifted toward an arrow mark. Thus the balance of coil impedance is lost when surface flaws 6 orthogonal to an eddy current 5 pass through. As a result, flaw signals are detected. In such a constitution, the sensitivity is increased, and at the same time the S/N is improved since the magnetic fields are concentrated at the knife edge part.

摘要： PURPOSE:To accurately control furnace temp., by detecting temp. in an inner cover, inputting the signal to fuel controller through communication bus to adjust flow rates of fuel and combustion air. CONSTITUTION:Temp. in the inner cover 2 is detected by a thermocouple 4 and the temp. signal is inputted to fuel controller through communication bus via meter mounting cart moving along fixed furnace. At first, a temp. indicating controller 10 calculates the difference between the detected temp. and a prescribed temp. to output the result to a fuel flow re indicating controller 11 and output it to a combustion air flow rate indicating controller 13 via an air ratio setting device 12. The controller 11 controls fuel flow rate flowing to a burner 7 through a flow rate adjusting valve 15, based on the difference between a prescribed value from the controller 10 and the detected flow rate of an orifice plate 14. The controller 13 controls combustion air flow rate through a flow rate adjuster 17 based on the difference between prescribed value of the device 12 and the detected flow rate of an orifice plate 16. In this way, temp. of a coil 3 in the cover 2 can be controlled at the desired value.

摘要： PURPOSE:To increase processing capability and to perform 100% inspections, by providing a plurality of upper and lower pairs of ultrasonic wave probes in the conveying direction of a steel pipe at a specified interval, rotating and sending the steel pipe in the lateral direction, and simultaneously measuring the outer diameter and the thickness of the steel pipe at plurality of measuring points. CONSTITUTION:A pipe 5 is rotated and sent in the lateral direction. With respect to the pipe 5, 4 pairs of ultrasonic wave probes 1 and 1',-4 and 4' are arranged so as to face each other with a specified interval L being provided. An interval (d) is set as piD/8. When the pipe 5 is rotated on a skid surface 6, 4 points on the outer diameter and 8 points of the thickness of the pipe are measured. The outer diameter is obtained by subtracting the sum of the distances between the probes and the pipe 5 from the interval L, and the thickness is obtained by performing the signal processing of multiple reflected echoes of the ultrasonic waves. Therefore, the processing capability is increased, and the 100% inspections can be performed for the steel pipes on a lateral conveying line.
