Definitions
- part of the zinc is removed at the outlet of the bath and the sheet or strip to combine all the remaining zinc with the iron.
- U.S. Patent No. 3,383,189 relates to a process to prevent the appearance of oxide on a galvanized strip in a zinc bath containing an aluminum additive.
- the object of the invention is also to produce a hot-dip galvanized sheet metal sheet or strip having all of the above-mentioned properties combined and which can also be implemented by means of the techniques used for steel without requiring any modification of the equipment, products or manufacturing sequences.
- the distance from the galvanizing bath surface at which the zinc coating deposited on the strip begins to exhibit this state of friability is a function of a number of variable factors. Consequently this distance can vary and to allow always to exert the desired mechanical action on the face of the strip in the appropriate temperature range of the latter, the brush 7 and the support roller 8 are mounted independently adjustable according to the path of the strip. It is thus possible to move the brush 7 and its opposing roller 8 along this path as shown for example in 7 * 8 'and 7 "8" in FIG. 1.
- FIGs. 4 and 5 there is shown in Figs. 4 and 5 an embodiment of a device for the implementation of the method according to the invention, for treating a single face of a sheet or strip.
- the support rollers 8 are mounted parallel so as to pivot in a support 15 which is adjustable both in height parallel to the path of the strip and perpendicular to it by means of two devices, for example with screws, 19 and 20 respectively. It is thus possible not only to move the axes of the rollers 8 relative to the axis. of rotation of the brush 7 but also adjust the pressure exerted by the device on the strip on either side of the latter, and thus also on the tension thereof.
- a support roller 8 is mounted above the shaft 9 of each brush and at a fixed adjustable distance from the latter and from the strip.
- this support roller 8 is intended to ensure, in conjunction with the opposing roller 8a forming part of the symmetrical device, the appropriate tension of the strip in contact with the brushes 7, 7a, without any transverse bending.
- the temperature of the strip on the one hand, at the level of the brush or brushes, and the temperature of the bath, on the other hand, are chosen so that the zinc reaches the level of the brush or the brushes with a temperature slightly higher than its solidification temperature.
- the first bucket has cracks and constrictions on seizure, and the following break systematically whatever the pressure of blank holder adopted, as a result of seizures at the entry radius of the matrix.
- Vickers microhardness tests carried out on the alloy have shown that the hardness of the layer is between 250 and 420 HV, depending on the stress state of the surface.
