Abstract: In studies of the technology of vertical hot galvanizing, it was reported that the liquid zinc area is ideal rectangular, however the actual shape of zinc liquid boundary is curved. In order to understand clearly the force distribution in zinc liquid, it is assumed in this paper that liquid zinc area is the rectangular region with chamfer. The experimental was carried out when liquid zinc dimensionless vertical height was 7.375~7.625, exciting current frequency was 3~7 Hz, dimensionless chamfer distance was 0.25, 0.5 and 0.75. The results showed that the electromagnetic force of zinc liquid decreases with increasing chamfer distance. Peak electromagnetic force of zinc liquid decreases with frequency increasing. Electromagnetic force becomes smoothly with the frequency increasing. The greater the chamfer of liquid zinc, the bigger the difference of the peak electromagnetic force and valley electromagnetic force.

Key words: vertical hot galvanizing, chamfer, liquid zinc, electromagnetic force
