METHOD AND APPARATUS FOR DESCALING METAL STRIP

摘要

A method is provided for descaling metal strip, such as titanium in a molten salt bath. The improvement eliminates the production of defects in the strip as a result of electrical arcing between the strip and the submersion rolls used to maintain the strip submerged within the molten salt bath. The method includes providing a portion of the roll with an electrically insulating coating so that the arcing between the strip and the roll is eliminated. A roll having a coating thereon and useful in molten salt bath descaling processes is also provided.
