摘要： PURPOSE:To provide the pad for fluid holding of a steel sheet which can hold the steel sheet a float in an always stable state without being affected by fluctuations in width and can suppress a blower cost as far as possible. CONSTITUTION:This fluid static pressure pad 1 consists of a box-shaped pad body 7 connected to a proper fluid supplying source and a pair of fluid ejection ports 2 formed in the transverse direction of the steel sheet in both end positions before and behind the pad body 7 along the pass direction. Moving nozzle plates 3 facing each other are installed on both sides in the transverse direction of the steel sheet between the above-mentioned fluid ejection ports 2. Baffle plates extending in the pass direction are integrally connected apart a spacing to the front ends of these nozzle plates 3. The ejection of the fluid even from the spacings between the above-mentioned nozzle plates 3 and the front surface plate of the pad body 1 is enabled.

摘要： PURPOSE:To allow a band plate to travel without meandering by providing the protruding top part of a gas pad face with a pair of V-slits formed in such a way that the V-bottom thereof disposed outside both width end parts of the band plate faces outward, and also with a pair of seal plates disposed outside the V-slits in such a way as to be parallel to the travel direction of the band plate and approximately right-angled to the arcuate face. CONSTITUTION:When a band plate 1 is shifted in the direction of an arrow mark 11, the whole V-nozzle 3 including its bottom 3-1 is covered with the band plate 1, whereas a V-nozzle 3' comes off the band plate 1, and only the V-end part 3'-2 of a V-groove is covered with the band plate 1. The band plate 1 on the V-nozzle 3 side is thereby lifted largely upward by the gas flow blown off upward from the V-groove 3-1, whereas the band plate 1 on the V-nozzle 3' side is slightly swollen in the lateral direction by the gas flow blown off from the V-end part 3'-2 but its upward lifting does not take place. As a result, the band plate 1 is inclined on a gas pad face 2, but is moved in the direction of an arrow mark 12 by the partial force P' of gravity P acting upon the band plate 1.

摘要： PURPOSE:To improve stable floating passing through property of a band-shaped member and permit a technology for floating and passing through plates without contact to be practically applied, by providing guide rollers capable of making inclination at an outlet of a band-shaped dislocation in a width direction and a floating gap in accordance with a passing through condition. CONSTITUTION:Guide rollers 3 capable of making inclination are provided at an outlet of a band-shaped member 1 of a pad 2 and its inclination is controlled in accordance with a passing through condition. As a result, a floating gap between the center of the band-shaped member 1 and an R side and an L side can be quickly corrected to an uniform value by inclining the guide rollers 3 disposed in the outlet direction of the band-shaped member 1 of the pad 2 when the band-shaped member gets out of position of the center in a width direction due to a change of external conditions and the like or it is inclined due to a difference of floating at the R side and the L side. Therefore, stable floating passing through property of the band-shaped member 1 can be greatly improved by an inclining method of the guide rollers, whereby a practical application of a technology for floating and passing through plates without contact is made possible.

摘要： PURPOSE:To decrease the installation area of a titled device and to eliminate the stagnation of gas between the electrode and the surfaces of a traveling strip by inclining adjacent two sets of plate-like insoluble anode pairs which are positioned respectively on both sides of the strip and face to each other into a V shape relatively with a horizontal plane. CONSTITUTION:Two sets of anode pairs 12, 13 are disposed right above a tank 11 so as to form a V-shape. The angle of inclination of the respective pairs 12, 13 relative with the horizontal plane thereof is changed according to the space between the anode pairs 12, 13. If the angle of inclination increases, the installation area of the device decreases correspondingly and the produced gas stagnates less. Slit nozzles 15 for ejecting an electrolyte are provided to each anode 14 so as to form a closed curve on the plane directing toward the strip S. The closed curve that the nozzles 15 draw is made into the square shape slightly narrower than the width of the strip S or the like. The electrolyte is supplied under pressure, via a casing 16, to the nozzles 15, and the strip S is held by the static pressure in the closed curve.

摘要： PURPOSE:To produce a one-side plated steel plate of high coating weights with compact installations by containing air bubbles in an electrolyte thereby preventing electrodeposition and forming a non-plated surface. CONSTITUTION:While a strip 4 guided by conductor rolls 3 travels in the space in an electrolytic cell 1 provided with liquid wells 2 in the bottom, it is plated by the electrolyte ejecting through the injection ports provided to electrode pads 5 installed on both sides of the strip 4. A pair of the pads 5 consist of hollow pads 5X and 5Y, and the plating soln. fed through electrolyte supply pipes 9 ejects like arrows through injection ports 7. Air bubbles are contained in the electrolyte through gas supply pipes 10 and electricity is conducted only to the electrode surface 8Y. The formation of the plating on the electrode 5X side is prevented by the air bubbles. The strip 4 is held stably at the center of the pads by static pressure.

摘要： PURPOSE:To effectively prevent vibrations and chambers of a strip, by providing >=2 couples of fluid blasting slits along breadth of the strip in a hydraulic pad that is a noncontact type controlling device for vibrations and cambers of the strip. CONSTITUTION:For instance, a steel strip 3, being drawn up vertically between a sink roll 4 submerged in a plating bath 1 in a vessel 2 and a top roll 5 placed on the upper side far away from the sink roll 4, is blown with the high pressure gas blasted from a wiping nozzle 6; hereby, the plating thickness is controlled to a desired value. Since the strip 3 is running at a high velocity therein, the strip 3 causes a vibration and a transverse camber C due to its tension. In order to diminish such vibration and camber, a couple of hydraulic pads 7 is arranged facing to each other along the line of the strip 3 on the upper side of the nozzle 6. A nozzle 8 of the hydraulic pad 7 is provided with plural slits 9 arranged in accordance with the characteristic of the line and the dimensional constitution of the strip 3; the high pressure gas is blasted from these slits 9 through a flexible pipe 11 and a tank 10 acting as a surge tank.

摘要： PURPOSE:To let holding power be most effectively acted upon a strip by making the spacings between the plural non-contact holding means installed along the transfer line of the strip and the strip subsequently larger as they go away from the stationary supporting points. CONSTITUTION:In the case of applying the foregoing non-contact holding means to continuous melt plating equipment, a strip 3 is passed in a plating bath 2 and is pulled up in the arrow direction at a constant speed and tension between the two stationary support points of sink rolls and top rolls. Fluid pads 7 are provided mutually opposedly so as to sandwich the transfer line of the strip 3 in the position above the gas wiping nozzles 5 closer to the sink rolls. The pads 7 are constituted by three sets of pads 7a, 7b, 7c by leaving spacings along the moving direction of the strip 7 and the spacings l1, l2, l3 between these three sets of the pads and the strip 3 are made l3>l2>l1 so that they become smallest on the stationary support side and become subsequently larger as they go away from the stationary support points. Even if the vibrations or warpages of the strip 3 during its movimg are caused, these are corrected within the permissible range.
