Effect of HCl in sulfate type coating electrolyte (mainly zinc sulfate)



I am a materials engineer, and I am in charge of design of continuous electrogalvanizing line for strip steel.What are the effects of using HCl as a pickling media( for pretreatment)with mainly sulfate type coating cells in horizontal line ? Simply, What are the results if HCl mixed with zinc sulfate in coating cell due to migration of HCl with strip ?

Thank you very much for your help.




HCL is for a fact,used as a reactant with Zinc. When you mix them together,they will fizz if temperature becomes to extremely hot. Therefore, I feel it would not be wise to use HCl with Zinc sulfate.
