Abstract
1324478 Galvanising ferrous articles JOHN LYSAGHT (AUSTRALIA) Ltd 13 Sept 1971 [25 Sept 1970] 42641/71 Heading C7F Apparatus for galvanising ferrous articles, e.g. steel sheets, comprises a kettle 6 containing a lead bath 5 upon which floats a flux cover 7 and a galvanising bath 11. Both the lead bath 5 and the galvanising bath 11 contain small amounts of aluminium to suppress the formation of a Fe-Zn layer on the sheet. The sheets run between guide rolls 9, 10, and a further set of rolls 12 to control the thickness of the coating. To maintain a constant aluminium content in the bath 5 a pool of molten Al-Zn 13 floats on the surface and is contained by weirs 14. The Al content of the pool 13 can thus be varied to vary the Al content in the bath 5. The preferred Al content in the bath 5 is between 0À0005% and 0À06% and in the bath 11 is 0À14%-0À30% (although it may contain up to 20% Al). In another embodiment Fig. 2 (not shown) the Al content in the lead bath (15) is maintained by having an additional lead bath (23) having a molten Al-Zn layer (24) floating on top. The lead baths (15) (23) are connected by conduits whereby some of the contents of one bath can be pumped into the other to achieve the desired Al content. A further method of controlling the Al content of the lead bath comprises adding Al or Al alloy ingots and sheets or Al-enriched Pb ingots, to the bath. In addition, alternative means for controlling the coating thickness may be used, for instance, steam or air blasts.
