Extending the life of steel galvanizing
kettle [India]
+++
Hi, we are Hot dip galvanizers of small articles in large no's and
use conventional and traditional methods not exactly perfect though
Just an idea.. we also have the problem of the steel pot slowly
getting eaten away by the zinc due to dross formation. Is it possible
to slow the reaction of dross formation by some electrostatic or
electrolytic means? by applying a voltage across the zinc and the
pot???

How much life are you getting out of your current kettle and how
much due you hope to get? Improving your burner system would probably
be the best way to extend kettle life. I assume your kettle is made
from steel with the proper steel chemistry (kettle steel). Impressing
a current to the kettle may not be possible with the high
temperatures.

Regular dross removal and agitation is essential (every 2 weeks
minimum). Kettle must be ultra low Si content. Low iron level in flux
solution (<1%)helps.
