摘要： PURPOSE:To enable to detect a wall thickness of the round pipe to be measured at all parts by a construction wherein a radiation source both relatively rotatable about the axis of the round pipe to be measured are disposed facing each other on an extension of the segment connecting two arbitrary apexes of an imaginary odd-apexes regular polygon, which apexes locate on the round pipe wall part. CONSTITUTION:An imaginary odd-apexes regular polygon, which has the same center as the axis of a round pipe 101 to be measured and has apexes locating on the wall part thereof, is arbitrarily specified. A position detector 107 detects each particular mark indicating that a straight line extended from the segment connecting two adjacent apexes of the imaginary polygon is made coincident with the path of radiation 105 emitted from a radiation source 103. A radiation detector 106 is disposed on the path of the radiation 105 to face the source 103. An arithmetic unit 112 performs given computation based on attenuated amounts of the radiation which are obtained by causing the radiation 105 to pass the same part of the round pipe 101 two times at different relative angles, thereby determining a wall thickness Xn at that part.

摘要： PURPOSE:To form a high-quality Zn vapor-deposited film on band steel by cooling the band steel entering a vapor deposition chamber to an appropriate temp. with a cooler when the high-temp. band steel leaving an annealing furnace is cooled and Zn, etc., are deposited on the steel. CONSTITUTION:The band steel 1 which is reduced and annealed in the annealing furnace 2 is cooled in the cooler 3 by blowing gaseous N2, etc., to an appropriate temp. allowing for a decrease in the temp. in a duct 6 and a vacuum sealing device 7, and introduced in the vapor deposition chamber 5 to form a high-quality Zn vapor- deposited film. In this case, the gaseous N2 jet pressure in the plenum chamber 3a of the cooler 3 is controlled to cool the band steel 1 at the outlet of the cooler 3 to an appropriate temp. When the control system is stabilized, the ratio alpha/alphaX 17 of the actual heat-transfer coefficient alphaX obtained by the inverse calculation from the pressure in the plenum chamber 3a to the theoretical heat-transfer coefficient alpha is stored in an arithmetic unit 14, the gaseous N2 pressure in a device 3C for supplying cooling gaseous N2 into the plenum chamber 3a is appropriately adjusted on the basis of the instruction data 15 for the production of the band steel 1, and the temp. of the band steel before entering the Zn vapor deposition chamber 5 is controlled to an optimum temp. for Zn deposition.

摘要： PURPOSE:To permit sure and quick changing over of both-faces plating and one-face plating by controlling both the temp. of a molten metal and the pressure of a vapor deposition chamber in the stage of subjecting a steel sheet to vacuum deposition plating of a metal such as zinc. CONSTITUTION:The vapor deposition plating of zinc is executed at a specific sheet thickness and width and line speed as well as under the conditions of 460 deg.C molten zinc temp. by using a vapor deposition device as shown in the figure with the relation between the pressure regulation of a vapor deposition chamber 10 and evaporation rate with the evaporation rate of zinc when the pressure in the chamber 10 is changed to 0.1-1.0Torr, the evaporation rate of the zinc decreases sharply under 0.4-0.5Torr pressure in the chamber 10 as shown in the figure. The evaporation rate decreases to =0.5Torr. The flow of the vapor to a duct 13 is, therefore substantially eliminated and the sure sealing is attained when a shutter 17 of an evaporation vessel 14 is fully closed. Since the evaporation rate can be more suppressed under the higher pressure of the chamber 10, the pressure in the chamber 10 is particularly held 2-3 timers larger than the satd. vapor pressure of the zinc bath, for example, >=3Torr. Both faces plating can be made again after the one-face plating simply by resetting the chamber 10 in which the vapor deposition is paused to the operating state of vapor deposition.

摘要： PURPOSE:To improve the efficiency of electromagnetic stirring by winding multiphase coils for generating a bipolar rotating magnetic field to a pair of iron cores disposed to face each other by a ring winding system and generating the bipolar rotating magnetic fields at the center between the coils. CONSTITUTION:Three-phase windings 2a, 2b of U-W are respectively wound by the ring winding system on a pair of the iron cores 1a, 1b disposed to face each other apart at the prescribed space maintained therebetween and a casting mold contg. a molten steel 3a or a solidified shell 4a of an ingot is disposed between the iron cores 1a and 1b. The magnetic flux 5a of the two poles is generated as shown by alternate long and short dash lines when current is impressed to the windings 2a, 2b of U-W from a 3-phase AC power source. The magnetic flux 5a forms the rotating magnetic field rotating in an arrow 6a direction around the central point 0' of the device on progression of the 3-phase AC period. The rotating magnetic field is slightly elliptical and has the large rotating force to be exerted to the molten steel 3a. The high stirring efficiency is thus obtd.
