摘要： PURPOSE:To obtain a cheap plate thermometer in which scanning is allowed at a measuring position and relatively low temperature lower than 600 deg.C can be measured while suppressing failure. CONSTITUTION:A radiation thermometer 35 (in a detecting unit 30) is installed on the outside of a furnace in order to measure the temperature of a band steel 1 placed in the furnace directly through a seal glass 40. The radiation thermometer is secured to the shaft of a drive unit 20 and supported on the furnace. The drive unit is then driven to rock the radiation thermometer itself thus scanning the detecting shaft in the lateral direction of the band steel. Detecting shaft of the radiation thermometer is normally secured to the center of the band steel and scanning is performed upon turn ON of a switch PB1. Scanning range is set within + or -45 deg.. Water cooling pipe is laid along inner peripheral wall of the furnace and the inner surface of seal glass is subjected to N2 purging. The radiation thermometer and the drive unit are provided with a water cooling mechanism and an air purge mechanism.

摘要： PROBLEM TO BE SOLVED: To quickly polish a pin sample without affecting component analyzing accuracy by arranging a wear plate in its slant attitude in the axial direction of the pin sample, and reciprocating the wear plate in the direction for running along a traveling polishing surface of a polishing belt. SOLUTION: A wear plate 8 is arranged in a position opposed to a pin sample A by sandwiching a polishing belt 1, and this wear plate 8 is arranged so that an inclined part of a Z shape 82 inclines in the axial direction of the pin sample A. A traveling polishing surface of the polishing belt 1 travels downward from above, and the rotational direction of the pin sample A and the traveling direction of the polishing belt 1 are set in the inverse direction. The pin sample A also operates so as to push the axial radial direction at a right angle against the traveling polishing surface of the polishing belt 1. The wear plate 8 vertically reciprocates so that the pin sample A is pushed against a part corresponding to a width L1 of an oblique part of the Z shape 82, and a polishing surface of the pin sample A is uniformly polished in a width of the Z shape 82.

摘要： PROBLEM TO BE SOLVED: To restrain the variation of moisture after humidifying to the blast air at the time of charging the blast volume according to performance of pressurizing at the time of changing over a hot stove. SOLUTION: During pressurizing, a target value SV2 of the pouring moisture quantity is decided so as to proportion to (target value SV of the moisture after humidifying-detected value PV1 of the moisture before humidity) × (blast volume PV3). Except during pressurizing, the target value SV of the moisture after humidifying and the detected value PV2 of the moisture after humidifying are inputted to a PID control unit 11 and the target value SV1 of the poured water quantity is decided by this arithmetic result.

摘要： PURPOSE:To improve emergency responsiveness by changing a control valve opening, by using a first electromagnetic clutch means and a first electric driving means in a normal opening control command, and by using a second electromagnetic clutch means and a second electric driving means driven by a battery in an emergency opening control command. CONSTITUTION:For inputting an ordinary opening control command S4, in response thereto, the first drive control means 31, 38 connect the first electromagnetic clutch CL to drive the first electric driving means M1. Thus, an opening of a control valve is changed. The opening is maintained by stopping the first electric driving means M1. Here, the second electromagnetic clutch SOL is not energized, and the second electric driving means M2 is inoperative. For inputting emergency opening control commands S1 to S3, by disconnecting the first electromagnetic clutch CL and connecting the second electromagnetic clutch SOL, the second electric driving means M2 is driven by a battery 37 to control the opening of the regulator valve.

摘要： PURPOSE:To prevent deviation of valve opening caused by fluid pressure to be applied to a valve body or a return spring, and to reliably close (or open) a valve in its action in case of power failure. CONSTITUTION:The rotation of a valve body, generated by driving mechanism fluid pressure of motor operated valve composed of a worm shaft 8, a worm wheel 10 and a valve body driving shaft 11 provided with gears 3G, 6 and 7, an electromagnetic clutch and a spiral spring 12 provided with an electric motor 1 and ratchet mechanism 4, 5, is stopped by a worm, and the rotation of the valve body, generated by the spiral spring, is stopped by the ratchet mechanism 4, 5, thereby the valve opening deviation is not generated. Moreover, since the clutch gear 7 is separated from the worm shaft in their action in case of power failure, the clutch gear 7, an intermediate gear 6, an output shaft 3 and the electric motor 1 not requiring the rotation are not rotated at all, the reliable, high-speed and smooth operation can be obtained, and the conventional inconvenience is not generated.

摘要： PURPOSE:To restrict variation of the ratio of the amount of discharged gas to the sucked amount of diluted air and keep properly a cooling capability by a method wherein the flow rate of fuel gas supplied to the input side of a tubular burner is detected, a pressure target value is determined in response to the detected flow rate and the pressure in a discharged passage of the discharged gas is controlled in a direction where the pressure approches the pressure target value. CONSTITUTION:Information about gas flow rates FG1 to FG5 and air flow rates FA1 to FA5 detected by a flow rate meter at each of zones is inputted at first. Then, gas flow rates FG1 to FG5 and the air flow rates FA1 to FA5 are added to get the fuel flow rates F1 to F5. In addition, predetermined weighing coefficients c1 to c5 for every zone are utilized to correct fuel flow rates F1 to F5 for every zone. Then, the maximum value is calculated in reference to the corrected fuel flow rates AF1 to AF5 in each of the zones and then a target value SP is outputted. Then, the target value SP is outputted to a pressure adjusting meter. Accordingly, it is possible to keep the cooling capability at its suitable value.

摘要： PURPOSE:To promote energy saving and labor saving by measuring fluctuations of position and rate for a molten steel surface in a mold as comparing with the settled values and then deciding on inspection and cleaning methods for steel materials based on this comparison. CONSTITUTION:A molten steel surface level detecting device 1 is arranged in the mold 13 and a slab length measuring instrument 4 is arranged at pinch roll part 4. At continuously casting of slab 14 by pouring the molten steel into the mold 13 from a tundish 11, signals of the molten steel surface level detecting device 1 and the measuring instrument 4 are inputted into a computer 2. Then, the signal of the device 1 and the signal of the slab length are joined together to store in the computer 2. Next, the inspection and cleaning methods are decided based on the comparison of the fluctuation of position and rate for the molten steel surface calculated from the molten steel surface level measuring value at shearing the slab 14 with the settled values respectively. As the effective inspection and cleaning is executed, the energy and labor savings are promoted.
