Aqueous blanking solution for solid film prelube forming operations

摘要: A blanking solution containing surfactants, corrosion inhibitors, and optionally biocides antifoam agents can be applied to steel blanks in a stamping or drawing mill prevent the transfer of solid film prelube lubricants from rolls mill. The surfactant is preferably nonionic which does not have any essential effect on coefficient friction when prelubed are stamped drawn form final part.
