摘要： PROBLEM TO BE SOLVED: To provide a high frequency induction heating unit which realizes down-sizing and low loss and improves operation efficiency. SOLUTION: The high frequency induction heating unit 1 has a coil conductor 3, a plurality of conductive plate 4 and a plurality of iron core. An assistant electrode plate 7 and dielectric member 6 are inserted to each conductive plate 4 and constructs a match condenser. By integrating the coil and the matched condenser like that, unit can be miniaturized and the coil between the fragile coil and the matched condenser can be reduced. Also, since high frequency current can be supplied from the high frequency power supply, high flexible coil having small diameter can be used and the operation efficiency of heat treatment can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a powder carbon graphitizing and baking apparatus capable of continuously baking, having low power consumption and high efficiency. SOLUTION: This apparatus is constituted of a ring-shaped furnace movable part 11 which is revolved around and equipped with a hearth 11a on the top and a tunnel-like furnace stationary part 20 forming an in-furnace space 30 on the furnace movable part 11. The in-furnace space 30 and the furnace stationary part 20 forming the space divide a circumferential space of 360 deg. into six zones. The furnace stationary part corresponding to each zone is equipped with a powder raw material feed part 40, a hearth heating/powder preheating part 20a, a powder temperature raising part 20b, a powder temperature retaining part 20c, a cooling part and a graphitized powder takeout part 41 after graphitization, respectively. The furnace movable part 11 is rotated once (360 degrees) in reaching from the first zone to the last zone so as to constitute the completion of the baking process of graphitization.

摘要： PROBLEM TO BE SOLVED: To stably draw out an insulating sheet and automatically stack the same by fitting the center of rotation of a pair of folding arms to a stacking table, and controlling the attitude of a suction pipe so that a vacuum suction hole keeps the state of being always attracted at right angles to the sheet. SOLUTION: An insulating film 1 is led out right above a stacking table 9 through a guide roll 8. One folding arm 3 is turned on a rotating shaft 4 rotated in a body with the arm to rise from the stacking table 9 toward the guide roller 8, and when a suction pipe 5 reaches a sucking position, it vacuum- sucks the insulating film 1 with vacuum sucking force exerted from a vacuum suction hole 6. The folding arm 3 is turned together with the rotating shaft 4 in the reverse direction to the above direction while keeping its sucking state, so that the suction pipe 5 is lowered toward the stacking table 9 to retract the insulating film 1 up to the upper surface of the stacking table 9 which is the folding position.

摘要： PROBLEM TO BE SOLVED: To optimize the pressure and flow rate of a high-pressure jet fluid and to maintain the cooled state of a metallic sheet to be rolled where good hot rolling temp. is kept. SOLUTION: In this device, the high-pressure jet fluid 17 is jetted in two stages from 1st jet nozzles 18 for jetting the high-pressure jet fluid 17 perpendicularly to a strip 12 and the 2nd jet nozzles 19 for jetting the high-pressure jet fluid 17 in inclined directions toward the upstream side of the traveling direction of the strip and collided against the strip. By the colliding pressure of the fluid caused by jetting and simultaneously evaporating/expanding actions of the fluid which enters the gap of a crack, scale is lifted, also crushed and removed as blowing off the scale along the surface of the strip. The pressure and flow rate of the high-pressure jet fluid 17 are optimized and the cooled state of the strip 12 where good hot rolling temp. is kept is maintained.

摘要： PURPOSE:To prevent unequal plating thicknesses and to improve the quality of a plated thin strip with a device for correcting the C camber of the steel strip in a plating liquid film wiping section to be used for continuous plating equipment and coating equipment for the steel strip. CONSTITUTION:The metallic thin strip 1 transported by passing the inside of the plating liquid is injected with the high-velocity gas jets from gas jet nozzles 3 for wiping the plating films near these nozzles 3, by which the excess plating liquid of the plating films sticking to the surfaces of the thin strip 1 is scrapped off. A C camber deformation is generated in the thin strip 1 near the nozzles 3 for wiping. This warpage quantity is detected by sensors 4 for detecting the warpage quantity arranged right above the nozzles 3. The magnetic forces of magnets 2, 2 for correcting the camber deformation are acted on the direction where the camber in this section is eliminated and the magnitude thereof, by which the camber of the thin strip 1 is corrected. Consequently, the specified distances between the nozzles 3 for wiping and the thin strip 1 are set constant in the width direction of the thin strip. The wiping effect is thus uniformized in the width direction and the plating films having the uniform thicknesses are realized.
