METHOD FOR COATING APPLICATION OF LUBRICANT TO MANDREL MILL BAR AND LUBRICANT COATING APPLICATION FACILITY TRAIN

摘要

PROBLEM TO BE SOLVED: To provide a method for coating application of a lubricant to a mandrel mill bar capable of forming a lubricating film of the adhesion property better than that of the prior art and capable of shortening the time for drying by enabling film thickness reduction without requiring large-scale facilities, such as heating apparatus and high pressure impartation apparatus, and a lubricant coating application facility train for implementing this method.;SOLUTION: After coating application of the lubricant 2, a sponge 5a is pressed or air is blown to the lubricating film to act an air bubble press- contacting medium to the lubricating film before drying of the lubricant 2.;COPYRIGHT: (C)2003,JPO
