Abstract
PURPOSE: To eliminate the defective metallurgical bonding of the clad metal and parent metal, and to improve the inspection yield of the product, by inserting the bar to be the inner layer into the tubular body to be the outer layer, and by applying the cold stretch-reduction, and then, by applying the hot elongation work.
CONSTITUTION: The solid rod 2 is inserted into the tubular body 1 of the round section, etc., and the reducing work is applied to this assembly; thereafter, the cold stretch-reduction is applied; hereby, the solid laminated billet 3, in which the inner surface of the tubular body 1 and the bar 2 are closely contating, is obtained. Next, the billet 3 is heated to the specified temperature and is applied the hot elongation work so as to be formed into the specified diameter rod. According to this method, the long size billet 3 can be easily obtained, and the parent metal and the clad metal are perfectly tight contacting at the stage of the billet 3, so that the perfect metallurgical bonding from top to bottom can be obtained by the hot elongation.
