Definitions
- the invention relates to a device for preventing the appearance of dendrites on the edges of metal strips during coating continuous electrolytic of said strips in radial type cells.
- a radial type cell has a tank which contains the bath electroplating, a partially submerged tape support roller, submerged anodes arranged facing the roller at a distance approximately constant, means for circulating an electric current between said anodes and a strip serving as cathode, means for scrolling in the tank of the strip supported by said roller and means for circulating said bath in the space separating the anodes from the band.
- the tape support roller usually has a coating electrically insulating, generally rubberized; eventually the surface of the central part of the roller is conductive, when the roller is used to supply electrical current to the strip which serves as a cathode.
- the object of the invention is to provide an edge masking device suitable for radial plating cells with soluble anodes and with stresses strong hydrodynamics, corresponding in particular to relative speeds between the strip to be coated and the electrolysis bath greater than 2 m / s.
- the subject of the invention is a device for masking strip edges metallic suitable for a radial type plating cell, comprising a support roller for said metal strip and anodes solvents arranged facing said roller, said device comprising a mask in the form of a narrow band arranged along each bank at immediate proximity to the surface of said roller, anchoring means to two ends of said mask and means for fixing said means anchor, characterized in that said mask comprises a band semi-rigid insulation, in particular of polymer matrix composite material, having, on its internal face turned towards said roller, on the one hand inner side oriented towards the middle of said roller, an offset on its entire length, on the other hand on the opposite outer side, studs in non-stick material, regularly spaced and fixed on said face internal and characterized in that, thanks to the fixing means, said mask is applied against the surface of said roller via of said studs and positioned so that said strands are engaged in said recess.
- the radial type electroplating cell supported by a frame not shown, includes a tank not shown which contains an electrodepositon bath, a roll 1 tape support partially immersed in the bath, soluble anodes 2 immersed arranged opposite the roller 1, means not shown for making circulate an electric current between the anodes 2 and the metal strip B to coating and serving as a cathode, scrolling means (not shown) in the tank of the band B supported by the roller 1 and means for circulating said bath in the space separating the anodes 2 from the strip B.
- These means for circulating the bath include ramps injection 3 placed at the point where the moving strip B enters and leaves of the space separating the anodes 2 from the roller 1, a space which is called generally "gap”.
- the electroplating cell also includes a device for masking the edges of strip B in scrolling course.
- This masking device comprises two masks identical 4 in the form of narrow bands each facing a bank 10 of strip B running and supported at each end 5 by anchoring means 14 supported by fixing means 6.
- the masks 4 are mainly consisting of a semi-rigid insulating strip 7, preferably made of material polymer matrix composite; this composite material can be by example reinforced with glass fibers.
- Each insulating strip 7 extends between the roller 1 and the anodes 2, about half a circumference of the roller 1.
- the insulating strip 7 has a recess 8 formed on the side interior oriented towards the middle of the roll 1 and supports, on the other side outside, regularly spaced studs 9, as shown in the Figure 1B.
- the two masks 4 are applied against the surface of the roller 1 by means of the studs 9.
- the contact or sliding surface of the pads 9 on the roller 1 is located in the immediate vicinity of the edges 10 of the traveling band B.
- the studs 9 consist of plates of non-stick material, of TEFLON type, fixed for example by gluing on the internal face of the insulating strip 7 outside the drop zone 8 (cf. FIG. 1B).
- the total thickness of the mask 4, i.e. the sum of that of the insulating strip 7 and pads 9, is much lower than that of the "gap" of the cell.
- the total thickness of mask 4 is approximately 8 mm.
- an insulating strip thickness 7 of approximately 5 mm and a thickness of stud 9 of approximately 3 mm For a mask thickness of approximately 8 mm, for example, an insulating strip thickness 7 of approximately 5 mm and a thickness of stud 9 of approximately 3 mm.
- the step 8 extends almost over the entire length of the insulating tape 7.
- the interval which separates the insulating tape 7 from the roll 1 corresponds to the depth said recess in the strip 7 added to the thickness of the pads 9.
- This interval must be much greater than the thickness of the band B.
- the residual thickness of the insulating strip 7 at the level of the offset 8 must be sufficient to ensure the masking function electric between the anodes 2 and the edges 10 of the strip B.
- This minimum thickness necessary to ensure the function of masking can be assessed in a manner known per se.
- the depth of the recess 8 in the strip 7 is approximately 2 mm; the interval between the insulating strip 7 of the roll 1 is then approximately 5 mm and the residual thickness of the strip insulating 7 at the step 8 is about 3 mm.
- the width of the recess 8 must be much greater than that edges 10, that is to say of the portion of strip B on which it is sought to avoid dendrites.
- this edge width 10 to be protected is approximately 15 mm, the width the step 8 is then about 30 mm.
- the total width of the insulating strip 7 is at least equal to the sum the width of the step 8 and the width of the studs 9; for a hook width 8 of 30 mm, it can typically be 120 mm approx.
- the connecting rods 13 and 15 are extensible in that one can adjust their length; they consist for example of two tubes fitted one in the other as shown in Figure 4.
- the connecting rods 13 and 15 are capable of sliding respectively on along the bars 12 and 11 in order to properly position the masks 4 opposite the edges 10 of the strip B.
- the anchoring means 14 supported by the ends of two connecting rods 13 as shown in Figure 3 provide a function of security, which allows the mask 4 to be released from its means of fastening 6, in the event of an accident, for example in the event of the strip catching B scrolling on said mask.
- the anchoring means 14 comprise a cylinder 17 and a clip 18.
- the cylinder 17 is integral with the ends of the two connecting rods 13 and maintained approximately parallel to bars 11, 12; according to the invention, the cylinder 17 is split over its entire length by a slot 19 oriented towards the entrance of the interval separating the anodes 2 from the roller 1.
- the fastener 18 crosses the slot 19 and has, at one end, clamping means for fixing the end 5 of the mask 4 and, at the other end, a prominent end cap embedded in the cylinder 17.
- the thickness of the nozzle is greater than the width of the slot 19 for not being able to pass through said slot.
- the fastener 18 remains integral with the cylinder 17 under the conditions normal stressing of the mask 4 on the fixing means 6, which are defined by the normal operating conditions of the cell.
- the mechanical and geometric characteristics of cylinder 17 and the end piece of the fastener 18 are determined in a manner known per se on the one hand to avoid the opening of the slot under the conditions normal stresses on the fastener 18 supporting the mask 4 when the cell is in operation, on the other hand to allow opening of slot 19 sufficient to allow the nozzle to pass as soon as the load on the fastener exceeds a predetermined threshold.
- the end piece may be of square section as shown in FIG. 4.
- the anchoring means 14 can also have a function of adjusting the position of the masks 4 by compared to those of the edges 10 of the strip B running on the roller 1.
- the cylinder 17 has a length very greater than the width of the mask 4; we can then slide the clip 18 inside the cylinder 17 over a stroke sufficient to effect said setting.
- the metal strip B to be coated is for example a steel strip of About 2 m wide and 0.4 mm thick.
- the position of the masks 4 is adjusted opposite the edges 10 of the strip metallic B to be coated, in particular by sliding the connecting rods 13 and 15 along the fixed bars 11 and 12.
- the position of the masks 4 is adjusted so that that the edges 10 on each side of the strip B are inserted in the offset 8 of the masks 4, as shown in FIG. 2.
- this device can advantageously be used to adjust precisely the position of the masks.
- this travel can be on the order of 10 mm on each side.
- the mask 4 in the position of operation is in contact with the surface of the roller 1 by through the studs 9; while strip B is running, roller 1 which turns therefore slides on the pads 9, which are non-stick.
- the tension of the masks 4 must not be too high, to limit the friction with the surface of the roller 1; however, it should be sufficient to properly keep the masks in place 4 facing the banks 10 of band B.
- zinc is deposited, in particular by scrolling band B in the cell using the means scrolling, by passing an electric current between the anodes 2 and strip B serving as a cathode while circulating the electrolysis bath in the "gap", in particular thanks to the injection ramps 3.
- the masks 4 remain firmly in place facing the edges 10 of band B, which allows to avoid the appearance of dendrites on the banks.
- the deposits on the banks do not offer an under-thickness and have a comparable morphology to that of deposits in the center of the strip.
- the relative speed between the strip and the bath is greater than 2 m / s.
- the Applicant attributes this surprising effect to the geometry of the masks 4, which, thanks in particular to the offset 8 and to the intervals which separate the pads 9, allows free circulation of the electrolysis bath, even in directions different from that of the tape running.
- the flexibility of the insulating strips 7 also contributes to the stability of the masks 4, since it is thanks to it that the masks 4 deviate slightly from roller 1 during operation, which further facilitates the circulation of the bath and limits the friction of the masks 4 on roller 1.
- masks 4 are both rigid enough to hold against the banks 10 and sufficiently flexible to take a stable position slightly away from the surface roller 1.
- Another supposed effect of the free circulation of the bath between masks 4 and the edges 10 of the strip is to allow a deposit having approximately the same thickness and the same morphology than at the center of the strip.
- the mask 4 emerges from the fixing means 6: in fact, under the effect of the tension exerted on the mask 4 at the time of the attachment, the fastener 18 emerges from the cylinder 17 by spreading the slot 19 to let its prominent tip pass.
