Definitions
- the invention relates to a device for guiding a strip in a liquid bath and is particularly applicable to the continuous coating of a metal strip by immersion in a container containing a bath of molten metal.
- Processes for continuously coating metal strips by passing through a bath of molten metal have long been known.
- the strip which is packaged in the form of a spool can be unwound and subjected, in a continuous line, to a stripping and annealing treatment under a neutral atmosphere, in an oven at the exit of which it is immersed in a container filled with liquid metal, such as zinc or an alloy of zinc and aluminum.
- the band must pass on two successive deflector rollers, respectively an upper roll which deflects it downwards and a roll immersed in the metal bath from which the band rises and leaves the bath in a substantially vertical direction, then is directed to spin and cool devices.
- the strip can then be subjected to a variety of finishing treatments such as a skin-pass and chemical surface treatments before being rewound.
- the baffle roll immersed in the bath rotates at a relatively high speed and, in addition, must withstand the tension of the web. It is therefore carried by bearings that are subjected to significant stresses and whose life is quite limited. These bearings can be immersed in the bath or placed outside thereof.
- the deflector roll is carried by two bearings which are mounted on two aligned fixed journals held by two vertical arms penetrating the bath.
- their constituent elements may be made of ceramic or, for example, of cobalt-based alloy.
- Such an arrangement is interesting because of the great ease of dismantling of the roll but the service life of the bearings remains limited.
- the introduction into the bath of the bearings and support arms requires expansion of the tray and therefore an increase in the volume of liquid metal.
- Another possibility is to mount the bearings on the side walls of the tank which must therefore be equipped with seals to avoid or, at least, limit the leakage of the liquid metal whose pressure at the joint, can be relatively important given the density of the metal and the immersion depth of the roll.
- JP-A-4346641 discloses a seal in which a linear motor in the wall determines an electromagnetic force for returning the metal to the inside of the bath.
- each axis of the roller passes through the side wall of the tank and is carried by a bearing mounted on u second wall separated from the side wall by a space in which are collected any leakage of liquid.
- Document J PA-10251819 describes a similar arrangement for a galvanizing device and provides for heating the liquid collected in the chute, to return it to the bath.
- Such arrangements complicate the installation and, in addition, further increase the distance between the bearing and the wall of the tray and, therefore, the length of the axis and the risk of shifting of the latter due to transverse forces applied by the tension of the band.
- the roller must be disassembled for maintenance or replacement, the hole of passage of the axis is largely open and it is therefore necessary, beforehand, to empty the tank.
- the invention makes it possible to provide a solution to such problems by means of a new arrangement of the support bearings for the axes of a submerged roll, which makes it possible, in particular, to ensure excellent centering of the roll and, consequently, to reduce risks of leaks.
- the disassembly and reassembly of the roller are much simpler than in the known provisions and do not require prior emptying of the tray.
- the invention is specifically intended for coating a strip with a liquid metal but could also be applied each time a roll is immersed in a liquid or aggressive fluid, for example an acid or an electrolyte .
- the invention therefore relates generally to a device for guiding a strip in a bath of liquid contained in a tank, comprising a deflector roll immersed in the tank between two side walls thereof and rotatably mounted around of an axis on two aligned support shafts passing respectively through the two side walls of the trough, perpendicular thereto, passing through an orifice of the wall and extending to a bearing bearing part in a bearing of centering placed outside the bin.
- each bearing of a roller shaft comprises at least two rotary support members mounted in a fixed housing and spaced apart from each other so as to withstand transverse forces applied to the roller, respectively an external support member and an internal support member placed as close as possible to the wall, the housing of the bearing being applied to a support plane surrounding the passage opening of the shaft and perpendicular to the axis thereof, along an outer face of the side wall of the tray, said wall being provided with means of centering the housing on the axis of the passage opening of the roller shaft.
- each roller support shaft has an outer portion extending between two bearing support members spaced apart from each other and an inner portion passing through the side wall of the tray and threaded with a weak play in a cylindrical duct formed on said wall and defining the passage opening of the shaft.
- This cylindrical duct extends over a length sufficient to place along said duct at least one sealing means by producing a return movement towards the inside of the tank of the metal penetrating into the annular space between the control shaft. roller support and the inner face of the cylindrical duct.
- At least one helical groove may be formed along the inner portion of the shaft threaded into the cylindrical conduit.
- the device comprises means for introducing a pressurized fluid into the annular space resulting from the clearance between the internal part of the shaft and the cylindrical duct limiting the passage orifice of the shaft, for maintaining sealing with a leakage rate of the fluid at least towards the inside of the tank.
- the side wall of the tray may comprise at least one induction means producing, around the conduit, cylindrical passage of the shaft a magnetic field capable of determine a return to the inside of the tank, metal infiltrated into the annular space between the shaft and the duct.
- each shaft of the roller passes with a small amount of rotation in an orifice of the side wall and is extended to an end face of the roll by an internal part threaded with a weak clearance in a conduit cylindrical formed throughout the thickness of the refractory lining of the wall.
- At least one of the two support shafts of the roller is removably attached by an inner end to a corresponding end face of the roller and is axially slidably mounted in the cylindrical duct between a tight roll support position and u separated roller disassembly position.
- the inner end of the shaft engages removably, by axial sliding, on a centering member formed on the corresponding end face of the roller.
- the inner end of the shaft and the centering member of the roller may be provided with mating parts respectively recessed and projecting so as to engage one another by axial sliding.

- the latter can be rotated by means for applying a torque to the outer portion of the shaft.
- the inner portion of the shaft is externally coated with a material resistant to wear and / or attack of liquid contained in the tray, such as a ceramic material.
- the inner part of the shaft which passes through the wall of the tank forms a centering pin mounted to slide axially in a hollow socket-shaped sealing part having a cylindrical outer face threaded with a small clearance.
- the shaft is subjected, in use, to an axial force directed inwards and is supported by a shoulder on the sleeve, for the engagement of the inner end thereof to the centering member of the roll.
- the sealing sleeve is constituted or, at least, externally coated with a material resistant to wear and / or attack of the liquid contained in the tank, for example a ceramic and the cylindrical duct passing through.
- the inner part of the shaft is made in a ring of refractory material.
- the housing of the bearing is applied to a rigid plate incorporated in the side wall of the tray and defining the bearing plane orthogonal to the axis of the passage opening of the shaft.
- the housing of the bearing forms, at its end facing the tank, a cylindrical tip centered on the axis of the passage opening of the support shaft and slipping axially in an internal bore of a rim the support plate surrounding the passage opening and having a flat face perpendicular to said axis on which is applied a clamping flange formed around the housing end, said planar face defining the support plane.
- the housing of the bearing is applied to the support plate by elastic means for exerting an axial thrust force capable of absorbing any expansions.
- the two rotary support members of the outer portion of the shaft are mounted in an outer cage forming a cartridge threaded into an axial bore of the bearing housing and can be removed from the housing. housing with the bearing by axial sliding leaving the housing applied to the centering plate.
- the centering of the shaft can be adjusted by introducing thin pieces of adaptable thickness between the cartridge carrying the shaft and a housing bore in which it is threaded.

- Figure 2 is a schematic view in axial section of the roller.
- Figure 3 is a schematic view, in axial section, of a roller centering bearing.
- FIG. 1 schematically shows, in cross-section, a device for coating a metal strip 1 by immersion in a bath M of liquid metal filling a tank 1 1 in which a deflector roll 2 is immersed.
- the strip 1 driven by unrepresented control means for scrolling in a longitudinal direction parallel to the plane of Figure 1, is deflected downwards by an upper baffle roll 12 and is wound on a sector of the submerged roll 2 so as to leave the bath M su ivant u u ascending direction substantially vertical.
- the strip 1 is thus covered on both sides with a layer of liquid metal whose thickness is controlled by a device 13, for example with an air knife.
- the baffle roller 2 is rotatably mounted on two aligned shafts 3a, 3b, centered on the axis 20 of the roller and each rotating in a bearing 4a, 4b. As indicated above, these two bearings 4a, 4b are placed outside the bin 1 1.
- Each of the two shafts 3a, 3b thus comprises an outer portion 33 rotating in the bearing 4a, 4b and an inner portion 32 which passes through the corresponding lateral wall 14a, 14b of the tank 1 1 through an orifice 15a, 1 5b, centered on an axis 1 0.
- it is releasably connected to the inner ends 31 of the two shafts 3a, 3b.
- the roller 2 may advantageously be provided, in the center of each of its end faces 21a, 21b, with a pin 22a, 22b centered on the axis 20 of the roller and forming a projecting piece which penetrates into a recessed portion, of conjugate shape, formed on the end 31 of the corresponding shaft 3a, 3b.
- At least one of the two shafts 3a, 3b is axially slidably mounted so as to be spaced laterally from the distance necessary to release the roller 2 in order to remove it from the bath M.
- the strip 1 is subjected to a tensile force and thus bears upwardly on the roll 2 by exerting transverse forces on the ends 31 of the two shafts 3a, 3b which are held by the bearings 4a, 4b .
- these bearings 4a, 4b are applied directly to the outer faces 16 of the side walls 14 of the tray 1 so as to reduce as much as possible the length of the inner portion 32 of the shaft 3 extending cantilevered between the end face 21 of the roll 2 and a bearing plane P of the bearing 4 orthogonal to the axis 10 of the through hole 15.
- each bearing 4 comprises, inside a housing 5, two rotary support members, normally conical bearings 42, 42 'which are spaced apart one from the other. the other a distance I to achieve a true embedding of the outer portion 33 of the shaft 3 threaded into the bearings 42, 42 'for supporting the transverse forces applied to the roller 2 by the tension of the strip 1.
- a tubular spacer 43 makes it possible to maintain the spacing between the two spaced bearings 42, 42 '.
- the assembly is housed in a cylindrical piece forming a cartridge 41 closed by two bottoms 45, 45 'and which is threaded into a housing 5, the latter being removably closed by a cover 51.
- the housing 5 is applied to a rigid plate 6 welded to the wall 14 and surrounding the passage opening 15, so as to define a bearing plane P perpendicular to the axis 10 of the orifice on which is centered the axis 20 of the roll.
- the plate 6 comprises a rim 61 with a blind bore 62 perfectly centered on the axis 10 and in which is engaged a tip 52 formed at the end of the housing 5 facing the wall 14, ahead of an enlarged part forming a flange 53 which is applied on an annular face 63 of the plate 6 defining the bearing plane P perpendicular to the axis 10, in a position for which the ends 31 of the two shafts 3a, 3b are engage the trunnions 22a, 22b of the centering of the roll 2.
- the housing 5 in which is placed the entire bearing 4 and the shaft 3 is applied against the bearing face 63 of the plate 6 by elastic pressure members 64, for example springs associated with bolts, which i engage in threaded bores formed on the flange 61 of the plate 6, in order to apply the flange 53 to the bearing face 63.
- elastic pressure members 64 exert, through the bearings 4 and axles 3, opposing axial forces on the two journals 22a, 22b of the roll 2 which maintain the latter by resisting the transverse forces resulting from the tension exerted on the band 1, and absorbing the differential d ictations due at the bath temperature M.
- thin shims 54 interposed between the cartridge 41 and the housing 5 make it possible to precisely adjust the concentricity between the axis 40 of the bearing 4 threaded into the housing 5 and the axis 10 of the bore 62 of the platinum 6. Due to this perfect concentricity obtained by centering the endpiece 52 in the bore 62 of the plate 6, it is possible to leave only a small clearance between the outer face 30 of the shaft 3 and the internal face of the passage opening 15, this small clearance being just sufficient to allow the high speed rotation of the shaft 3 about its axis 40 which is perfectly aligned with the axis 10 of the orifice 15.
- the two bottoms 45, 45 'of the cartridge 41 are provided with annular seals 45, 45' allowing the rotation of the shaft ensuring the sealing of the bearing whose lubrication and cooling are provided by circuits arranged, conventionally, in the cartridge 41 and carrying a lubricating fluid and a liquid or a cooling gas.
- the maintenance of the seal between the shaft 3 and the side wall 14 of the tank 1 is ensured along a cylindrical duct 7 formed in a sealing ring 71 and extending over a length sufficient to place sealing means returning to the inside of the tray the metal infiltrated into the annular space 72 between the shaft 3 and the conduit 7. It is necessary, in fact, to allow the rotation of the tree
- the shaft 3 thus comprises an outer portion 33 maintained in the bearing 4 and an inner portion 32 which extends along the conduit 7 to its end 31 of centering of the pin 22 of the roller 2.
- the thickness of the game 72 may be limited.
- various sealing means not opposing the rotation of the shaft 3 can be used to prevent metal leakage.
- the outer surface of the portion 32 of the shaft 3 extending in the conduit 7 may be provided with a groove in a helix determining, under the effect of the rotation of the shaft 3 and the sleeve 8 , the retention and the inward return of the metal able to infiltrate the annular space 72.
- annular channels 73 fed by a compressed gas, preferably a neutral gas such as nitrogen, so as to arrange a kind of fluid bearing along the conduit 7 between the shaft 8 and the wall 14 of the tank 1 1, the gas being injected at a pressure a little greater than the pressure of the liquid metal bath M, given the depth of immersion and the density of the metal, so as to provide a slight gas leakage flow into the tank.
- a compressed gas preferably a neutral gas such as nitrogen
- the side wall 14 of the tank 1 1 is generally covered with a refractory coating R in the thickness of which the duct 7 can be formed.
- this cylindrical duct 7 is formed in a ring 71 of refractory material which is fitted into a counterbore formed on the internal face of the plate 6 and extends over the entire thickness of the refractory coating R.
- this portion 32 of the shaft 3 may be coated with a wear-resistant ceramic material.
- internal 32 of the shaft 3 has a reduced diameter and forms a centering pin on which is threaded, with a simple sliding game, a tubular sealing member 8 in the form of a hollow sleeve having a cylindrical outer face 80 passing with a low clearance 72, in the duct 7 of the refractory ring 71 and which is closed by a bottom 81 forming the inner end 31 of the shaft 3.
- the opposite end 82 of the sleeve 8 forms an annular face of support on a shoulder 35 of the shaft 3 limiting the outer portion 33 thereof at the plate 6, the outer face 80 of the sleeve 8 having the same diameter as the outer face 30 of the outer portion 33 of the shaft 3, so as to form a continuous face.
- the bottom 81 of closure of the bushing 8 forms a female cone 83 in which is engaged a conical male cone formed on the spindle 22 of the centering roller 2.
- the shaft 3 is mounted axially fixed in the housing 5 of such that, when the latter is applied by the elastic pressure members 64 against the plate 6, the two sockets 8 associated with the two shafts 3a, 3b and pushed by the shoulders 35 exert opposite axial forces on the two journals 22a, 22b of the roller 2 which is thus secured by friction with the two shafts 3a, 3b which, thanks to the arrangements just described, are perfectly centered on the axes 10 of the two orifices 15a, 15b and aligned with the axis 20 of the roller .
- This can be mounted on its two bearings 4a, 4b madly but it can also be rotated about its axis, to control the running of the strip, by means of a motor device 23 set in rotation on the one of the trees 3b of the roll.
- inductors 74 generating static or sliding magnetic fields. that i can add their effect or replace the pressurized gas to seal the tray 1 1 at the orifice. It should be noted that these inductors 74 can also be used to heat the refractory ring 71 around the duct 7 in order to maintain at its melting point the liquid metal that can infiltrate into the annular space 72 and to favor the return of this towards the inside of the tank.
- inductors may also be installed in the refractory lining R of the side wall 14 of the tank 1 1 in order to heat the entire device.
- the metal that has been introduced into the annular space 70 may be advantageous to allow the metal that has been introduced into the annular space 70 to solidify, thereby ensuring complete sealing.
- the ring 71 can be heated by means of the inductors 74 to return the metal to the liquid state to allow the tightening of the two shafts and the engagement of their ends 31 on the journals 22a, 22b of the roll 2.
- each support shaft 3 and the corresponding end 21 of the roller 2 could be made in another way, for example by providing at the end 31 of the shaft 3, a male conical part penetrating into a conjugate profile cup, formed on the end face 21 of the roll 2.
- the invention has been described in the case of a coating device but could also find an application each time a roller must be kept immersed inside a liquid or an aggressive fluid and that It is therefore advantageous to place the bearings of the roller outside the tank, ensuring a sufficient seal.
- such arrangements could be employed to maintain a baffle roll within an acid tray in a metal strip stripping facility.
- the use of a sealing sleeve of ceramic material would better withstand the attack of the acid.
- the walls of the tray are usually covered with a refractory lining. It is then possible to provide the conduit 7 for passage of the shaft 3 in the manner described above and shown in FIG.
- the cylindrical duct could be made in a tubular part extending inwardly, in the extension of the orifice of passage of the shaft, and having a length sufficient to seal.
