The influences of 11 elements in sheet steel, temperature and Al content in zinc bath on the adhesion were investigated by use of continuous galvanizing line and laboratory galvanizing simulator. The adhesion was remarkably affected by Si in the steels, the temperature and Al content.The influences of Ti, Si and P in the steels on Fe-Zn alloying rate were also investigated. Ti accelerated the alloying rate, while Si and P slowed down it in the zinc bath containing Al. In the case of pure zinc bath, addition of these elements accelerated the rate. Based on the SEM observation of interface between alloyed layer and steel substrate, a model illustrating the adhesion and alloying rate has been proposed.
