| Abstract: | According to the actual production situation of a 1 700 galvanized thin gauge product, the scratch of sink roll of the thin gauge galvanized product under 0.35 mm was studied. The influencing factors including the roll system structure and working condition were analyzed. In addition, the relationship between the different friction modes and the friction coefficient was determined by Striebeck curve. Finally, the factor affecting the sink roll scratch was found. Through the tension optimization of the cooling tower and the assembling improvement of the sinking roll, the problem of the scratch of the sink roll in the zinc pot has been effectively solved, and remarkable application results have been achieved. |
