摘要： PURPOSE:To accurately detect an overlapped part by a simple constitution by a method wherein distances from the surface and the rear surface of a line up to the upper surface and the lower surface of a belt-shaped material are measured and the plate thickness of the belt-shaped material is operated by using two measured values. CONSTITUTION:An upper-part range finder 4 and a lower-part range finder 5 are installed respectively on the surface and the rear surface of a line at a mounting interval S(mm). A distance x1 up to the upper surface of a preceding strip 1 is measured by the range finder 4, a distance x2 up to the lower surface of a succeding strip 2 is measured simultaneously by the range finder 5, and a plate thickness tx(mm) at the overlapped part of the strips 1, 2 is found by a plate-thickness operation device 6 by means of a formula of tx=S-(x1+x2). Then, an overlap judgment device 7 sequentially compares the found plate thickness tx with a prescribed reference value, and the position of the overlapped part of the strips is judged. Thereby, the overlapped part can be detected by a simple constitution.

摘要： PURPOSE:To provide a traveling control method for carrier device which can secure the high stopping accuracy of the vehicle by controlling best the traveling pattern of the device. CONSTITUTION:The creeping time of a carrier device 24 is measured while the device 24 is carrying the goods. Then, the difference is calculated between the measured creeping time and the creeping time that is previously calculated. Based on this calculation data, the highest speed and the speed reduction rate of the device 24 are corrected. Thus, the next traveling pattern is decided for the device 24.

摘要： PURPOSE:To prevent a jumping up of cutting pieces by a lower blade and a collision of an upper blade and a following strip, and to improve the productivity extensively by inclining a plane including the upper and the lower drum cores simultaneously with the shearing of the strip. CONSTITUTION:Drum shear blades 4a and 4b are lapped, and in the instant that a strip 1 is cut, a hydraulic pressure is applied to a tilting cylinder 8 at the lower dead center, so as to incline a plane including the shaft cores of the upper and the lower drum bearings 6a and 6b at the angle theta to the advancing direction of the strip 1. The shaft 6a is moved the amount x=Dsin theta/2 in the strip advancing direction, and the shaft 6b is moved the same amount in the reverse direction. (In this formula, D is the diameter of the drum.) To the peripheral speed V of the drum, the edge speed of the upper blade 4a is made as the speed v+DELTAv adding the moving speed DELTAv in the inclination, while the edge speed of the lower blade 4b is made as v-DELTAv. Consequently, a bending of the tip of the blade can be prevented.

摘要： PURPOSE:To prevent surely the rupture of a strip in the starting stage by exerting successively increasing tension to the strip between the respective stands of a tandem mill having plural stands from the front stage toward the rear stage of the stands with the slight rotation of rolls so that the final tension attains the prescribed valve or above. CONSTITUTION:The strip 1 is passed to the tandem mill having the plural stands S1-S4. The tension on the strip 1 is measured by tension meters T1-T3 between the stands and the tension value thereof is adjusted by the slight rotation of driving motors M1-M4 by a control circuit C to the successively increasing tension from the upper stream side toward the down stream side so that the final tension attains the prescribed value or above. The rolling is started in this state, then the rolling is started without slackening of the strip 1 between the stands are the rupture of the strip in the starting stage is surely prevented.

摘要： PURPOSE:To prevent axial oscillation when a load is less, by providing a resistance and diodes in parallel on the input side of a current regulator, and inputting a current command to the current regulator through the resistance during light loading or through the diode during heavy loading. CONSTITUTION:The driving current (i) of a driving motor 14 is regulated by a current regulator 22 to coincide with a current command generated in accordance with the deviation between the rotational speed of the motor 14 and a set value. On the input side of this regulator 22, a resistance 30, and diodes 32 and 34 arranged in the opposite directions are provided in parallel. Then, said current command is inputted to the regulator 22 through the resistance 30 during light loading wherein a backlash is caused, or through the diode 32 or 34 during heavy loading wherein no backlash is caused.

摘要： PURPOSE:To conrol the tension distribution of hoop in a furnace at need, by controlling the tension of helper rolls other than standard helper roll copying with the temp. pattern corresponding to the tension pattern in accordance with the actural detected value of the tension of a standard helper roll. CONSTITUTION:A digital unit such as a computor 1 outputs a tension reference value ST and a set value for tension deviation TR in accordance respectively with the speed Sp, the tension Te, the size Si of hoop, and the temp. pattern TP. The reference value ST is given as a constant value to an automatic tension regulator ATR2 and actual deviation is given as measured value AT from a tension detector TM3. Then the ART2 outputs a tension command at that time to an operator 4 in accordance with the reference value ST and the measured value AT. The value TR is given to all multiplying circuits 411-41n which constitute the operator 4 from the computor 1, in that case the set values are given step by step from the circuit 411 corresponding to the helper roll arranged just before the reference roll to the circuit 41n corresponding to the first helper roll in the heating zone.

摘要： PURPOSE:To surely peel an amorphous strip from a cooling roll and to coil the strip without any breakage by pushing a magnetized leader tape to the strip just before peeling point of the amorphous strip stuck to the roll and weakening the stickness between the cooling roll and the strip. CONSTITUTION:The magnetized leader tape 8 is coiled with a coiling reel 11 from a supplying reel 7. By accelerating the coiling reel 11, the magnetized leader tape 8 is synchronized with peripheral speed of the cooling roll 5, and a pushing roll 15 is pushed with a cylinder 16 to push the tape 8 to the roll 3. At the time of supplying the molten steel 1 on the roll 3 by ascending a stopper 4 of a tundish nozzle 3, the molten steel 1 on the roll is rapidly cooled to form the amorphous strip 6 and reach to the lower end part of the roll 5. The strip 6 reached to the lower end part of the cooling roll 5 is pushed with the pushing roll 15 and the stickness to the cooling roll 5 is weakened and the strip is attracted with the magnetized leader tape 8 and separated from the roll 5. The strip 6 attracted to the magnetized leader tape 8 is coiled to the coiling reel 11.

摘要： PURPOSE:To prevent the buckling in coil of a strip coil by detecting the position inside a tension reel of an expand rod via a position detector and by detecting the presence or absence of a spool based on the detected value thereof. CONSTITUTION:The cylindrical face is formed by the plural reel hubs 3 having an inclined curved face 3a at the inner side and the expand rod 4 equipping with the inclined curved face 4a which abuts with sliding to the curved face 3a is arranged as well. Moreover, the rod 4 is linked with a piston 5a and a rack 6a is formed at the tip of the cylinder rod 6 thereof. The rod 4 is moved upto the stroke end in case of the spool 2 being not fitted, when the reel hub 3 is expanded via the sliding of the inclined curved face 3a, 4a. In this case, the unfitting of the spool 2 is decided with the signal of the rotation quantity of the pinion 7 which is engaged with the rack 6 being transmitted to a position detector 8 and comparison part 9. Consequently, the buckling of the strip soil can be prevented.
