Estimating the term…
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.
A bearing system for a hot-dip plating apparatus, comprising:
A continuous hot-dip plating apparatus, including a predetermined quantity of molten plating metal in which a metal strip is immersed for plating with said molten plating metal, comprising:
In a continuous hot-dip metal plating apparatus including a roll member for assisting the transport of a metal strip to be plated, and a bearing having a surface against which the metal strip causes the roll member to exert a force during the transport of the metal strip, said roll member and said bearing being immersed in a predetermined quantity of molten plating metal during the hot-dip plating process, the improvement comprising:
