ABSTRACT:
A continuous hot-dip plating apparatus has a roll assembly having superior resistance to erosion caused by the hot melt plating metal, as well as high resistance to wear of the shaft and bearings, which are immersed in the hot melt of the plating metal. A ceramic material is mounted on the sliding portions of the metallic roll shaft to make sliding contact with the metallic bearings and/or on the sliding surfaces of the metallic bearings which contact the metallic roll shaft. A clearance is left between the shafts and bearings to hold molten metal thereinbetween for lubrication.
