摘要： PURPOSE: To make the flow rate density distribution of cooling water in the transverse direction of a metallic strip uniform and to lessen the nonuniform cooling at the un-stationary time at the time of turning a stop valve on and off by providing a hairpin nozzle with the stop valve and an opening degree regulating valve and regulating the cooling water flow rate. CONSTITUTION: This cooler of a pipe laminar system is installed on a run-out table on the outlet side of a hot finishing mill and is mounted with the opening degree regulating valve 4 together with the hairpin nozzle 1 and the stop valve 3. The opening degree regulating valve 4 changes its opening rate by the vertical movement of a bolt screw, thereby changing the flow rate density of the cooling water in the transverse direction of the metallic strip. Since the hairpin nozzle 1 is provided with the stop valve 3, the generation of the water hammer which takes place at the time of the transient on and off of the stop valve 3 is lessened to a negligible level. The responsiveness at the time of discharging the cooling water and the responsiveness at the time of water draining are improved by providing the hairpin nozzle with the stop valve 3 nearer the discharge port.

摘要： PURPOSE:To prolong the service life of a metal blade and to reduce the necessary volume of the blade by shrink fitting the face parallel to the axis of the stairway of the base metal having a step like inner periphery in the axial direction to the face parallel to the axis of the stairway of the annular metal blade having a step like outer periphery in the axial direction. CONSTITUTION:A blade is composed of a base metal 2 to which a face 3 having the step like outer peripheral face of a metal blade 1 and parallel to the axis of the step thereof and a face 4 having a step like inner periphery in the axial direction and parallel to the axis of the step thereof are press-fitted by shrink fitting. A compressive stress is generated in the circumferential direction of the blade tip part of the blade 1, the size thereof is reduced toward the center, the stress in the circumferential direction of the tooth tip part of the blade 1 generated at shearing time and the stress distribution by the shrink fitting are composed and the tensile stress at the tooth tip part of the blade 1 is reduced. The life of the blade 1 is therefore prolonged drastically, the necessary volume is reduced with its simple structure because of a tapered part being not provided in the shape thereof and the manufacture is simplified as well.

摘要： PURPOSE:To make possible re-sampling from the same specimen tank by arranging so that a turntable on which plural specimen tanks are placed is halted at a prescribed sampling position and, when a robot has completed sampling, the tanks are raised under vibrations to equalize the recesses in the powdery material. CONSTITUTION:A sensor 5 receives specimen tank number signals from a CPU and detects the tank number by the signal holes of an encoder pattern 4. In case of different specimen tanks, the turntable 1 is revolved and the target specimen tank 3 is moved to a sampling position and accurately stopped by a fixed position stop sensor 7 and a fixed position stop magnet 6. A general-purpose robot performs automatic sampling. After its termination, a motor 14 of the specimen tank lift device is driven and a cam 13 is turned to raise the lifting shaft 12 to elevate the tank 3 into contact with a sample arm while vibrations are given to the specimen tank by a vibrator 10 to equalize the powdery material in the tank.

摘要： PURPOSE:To automate the entire stage so as to lessen manpower and to improve the accuracy of analysis by analyzing the combustion gas generated when a ceramic boat contg. a sample is inserted through a combustion pipe by a robot hand into an electric furnace by a prescribed method thereby determining the total sulfur content. CONSTITUTION:A sample is sampled, weighed and put into the ceramic boat by the robot hand. Such boat is inserted into the tubular electric furnace 5. A valve 7 is opened, after the prescribed heating treatment, to feed oxygen through an oxygen feed port 8 into the furnace 5 to burn the sample of cool or the like in the boat and to fix the sulfur in the combustion gas as a sulfuric acid by the aq. hydrogen peroxide soln. in an absorption tank 9. An NaOH standard soln. is fed from an NaOH standard soln. tank 13 to the tank 9 via an electrically driven buret 11 and the sulfuric acid is quantitatively determined by titration. The quantity of the NaOH standard soln. is detected by a metering pump 12 by which the total sulfur can be quantitatively determined. These analytical operations are controlled by an analysis control part 15 and an automatic titrator 14.

摘要： PURPOSE:To limit C warping of a cylindrical body within the range that does not cause impediment for practical use in rewinding a band steel from a coil, bending it by a bending machine and forming into a cylindrical body by a rotary guide ring, by arranging a pay off reel and a rotary guide reel in the same side with the bending machine. CONSTITUTION:A band steel 1 on a pay off reel 2 is rewound and bent by a vertical bending machine 3 to a bent band steel 4 having a specified curvature, and wound on a rotary guide ring 5. When the band steel 4 is wound once on the guide ring 5, it is cut at a position A, hung out from the guide ring, and both ends are welded to manufacture a cylindrical body. In this case, as the generation of C warping in the cylindrical body is unavoidable, the pay off reel 2 and rotary guide reel 5 are arranged in the same side with the bending machine 3. Direction of bending of the band steel when pulling out the band steel is made similar (positive) to the direction of bending when winding on the guide ring 5, and C warping is made small to the degree that does not cause impediment practically.

摘要： PURPOSE:To form a cylindrical body having uniform distribution of curvature in rewinding a band steel from a coil, bending it by a bending machine and forming into a cylinder by a rotary guide ring, by providing a guide roll between a pay off reel and a bending machine. CONSTITUTION:A band steel coil 1 on a pay off steel 2 is rewound, bent into a specified curvature by a vertical bending machine 3 to form a bent band steel 4, and wound on a rotary guide ring 5. When the band steel 4 is wound once on the guide ring 5, it is cut at a postition A, hung out from the guide ring 5 and both ends are welded to manufacture a cylindrical body. In this case, a guide roll 10 is provided between the pay off reel 2 and bending machine 3. For outer diameter side of the coil 2, angle of entrance is kept constant by the guide roll 10. For a part of inner diameter side, a cylindrical ring is formed without controlling the angle of entrance by the guide roll 10. Thus, a cylindrical ring having uniform, stable curvature can be manufactured simply.
