Molten metal plating apparatus

摘要

In a molten metal plating apparatus all surfaces of a sinking roller and a supporting roller to be in contact with a molten metal are coated with iron silicide films. A bearing comprises a holder made of a heat resistant steel and lined with a carbon-carbon fiber complex material. A surface of the holder is coated with an Fe3Si film similar to the sinking roller. There is an Fe3Si film on a surface of a shaft portion, and the Fe3Si is in contact with and slides on the carbon-carbon fiber complex material.
