Abstract

1. Apparatus for galvanising ribbed tubes, the apparatus having components which are arranged in line, one behind the other, at one treatment level, which are connected by an automatically operating conveyor device with horizontal and vertical support, guide and driving rolls, or, in the preheating area, with a conveyor chain device and which comprises a feed facility (1), a degreasing facility (2) with a blow-off device for the degreasing medium, a washing facility (3) with a blow-off device for the washing medium, a dipping facility (4) with a blow-off device for the dipping medium, a washing facility (5) with a blow-off device for the washing medium a preheating furnace (6), a galvanising furnace (7) with a protective atmosphere, a blow-off device (13) or a device for removing excess zinc, as well as a cooling and drying facility (8) with nozzles supplied with water and air and, if necessary, a chromating facility (9) with a blow-off device for the chromating medium, wherein the galvanising furnace (7) for receiving an alloy of molten zinc has a melting area (18), a galvanising pan (12) arranged over the melting area, a zinc charging area (20), wherein the molten zinc can be pumped from the melting area (18) into the galvanising pan (12) which has an overflow, and wherein the melting area (18) and the zinc charging area (20) are separated by a partition extending downwards into the zinc.
