Improvement of line productivity and of immersed hot dip galvanizing roll lifetime by dross build-up-control

Objective

The high standard of hot dip coating quality for automotive and industry markets requires no contact between dross and steel sheet. Improvement in terms of coating quality and line productivity can be achieved by decreasing the progressive adhesion of dross on immersed rolls.

The objective of this project is to increase the immersed hot dip galvanizing roll lifetime of 30% and consequently line productivity and coating quality by controlling dross build-up phenomena.

After identifying on industrial lines the main parameters of dross build-up, some laboratory simulations and modelling work will help us to understand the mechanism explaining dross build-up and to propose, evaluate and test some industrial solutions to avoid it.
