ABSTRACT:
A slide structure comprises a roll shaft and a roll bearing. A whole circumference of the roll shaft is made of a sintered ceramics body. A sliding surface of the roll bearing is constructed by inserting a cermet into a carbon-carbon reinforcing graphite member. A continuous hot dipping apparatus has a roll supported and rotated in a molten metal bath. A sliding surface of the roll shaft and the roll bearing employs the slide structure. The corrosion resistivity and the wearing resistivity can be improved and a long service life can be attained. The slide structure comprised of the roll shaft and the roll bearing can be smoothly rotated by decreasing the friction coefficient of the slide structure.
