To protect semi-finished products against corrosive attacks, it is necessary to cover them with a protection fluid existing of oil in an organic solvent mixture. After the evaporation of the solvent the oil remains as a clear corrosion preventive film providing displacement of moisture. The continuous treatment of products implicates a shift of the oil-to-solvent ratio in the fluid. Hence the wetting of the products shows various layer thicknesses during operation and the protection against corrosion is not on the same quality level.
