Current technologies for the control of zinc in high-speed galvanizing and galfanizing lines.
Galvanizing today:
Galvanizing, the last step which is leading to the fact that we get a good product or not, can today be controlled fully automatically by the use of active control techniques of the zinc coating combining Eddy current sensor and Nitrogen wiping systems.
The consistency of the results obtained on long term, as well as the possibility to anticipate a problem of coating quantity is giving the possibility to avoid the production of non-conform material and is therefore leading to some substantial savings on the line.
The operators can concentrate themselves even more on the threading-up operations and no longer have to care that much for the permanent running of the vertical draught. This tool will open some new exploitation possibilities of the lines at much better costs that are also better controlled than in the past because it ensures a permanent control of quality at the exit of the product from the line.
