Description

NedCoat Groningen is part of the Ned-Coat Group; NedCoat is a total provider in surface treatments for metal objects. It protects and decorates metal by means of hot-dip galvanising, powder coating, wet painting, duplex systems and anodising.
At NedCoat Groningen, steel objects are hot-dip galvanised. A highly specialised process in which the objects are completely immersed in liquid zinc. On 28 November 2007, we were able to observe this process in the old galvanisation plant. NedCoat Groningen has now moved into a new, state-of-the-art galvanisation plant. We now have the opportunity to see the latest state-of-the-art in hot-dip galvanising in the new galvanising plant.
NedCoat Groningen's new galvanising plant is distinguished in particular by a mixed buffer system for crossbars, highly automated logistics and a fully enclosed pre-treatment area.
Crossbars are used to hang objects that are presented for galvanising. Hanging and removing these objects is labour-intensive and is carried out on so-called lifting racks. These lifting racks are linked to a buffer system with which the crossbars are exchanged. In this buffer, crossbeams with objects to be galvanised and objects already galvanised are mixed together. A fully automated buffer crane switches the right cross section between the six lifting racks and the thirty positions in the buffer. Furthermore, the buffer ensures a constant supply and discharge of traverses to and from the production line. Important performance indicators when hanging and removing objects from traverses are the average traverse weight and the average hanging and removal time.
The production line consists of a closed monorail track with a total of six monorail cranes. At the beginning of the line, a traverse is picked up from the buffer and brought into the closed pre-treatment. Here, the contour of the suspended objects is scanned. If the objects are hung too wide, the traverse is rejected for further handling. If the traverse is approved, an immersion sequence of degreasing, rinsing, pickling, double rinsing, fluxing and drying follows. This immersion sequence is completed fully automatically. For this purpose, a recipe is provided when the materials are attached, which specifies immersion times, immersion and pick-up speeds and leakage times, among other things.
Immersion in liquid zinc is not automated and remains traditional human work.

For the benefit of people and the environment, the aggressive vapours of the pre-treatment are completely sealed off from the outside world. A strong fan continuously creates a negative pressure so that air is permanently sucked in from outside. Before the extracted air is blown out, it is cleaned using a scrubber. The captured acids are returned to the pickling tanks, creating a closed system without waste streams.
NedCoat Groningen's new galvanisation plant is the most modern in the Benelux. Here, we can see the latest production techniques in the field of surface treatment with zinc.
