MPROVEMENT OF TECHNOLOGY OF PRODUCTION OF COAXIAL LAMELLAR METAL BILLETS

Abstract

The results of experimental research of optimal modes of Plastic Forming coaxial layered metal blanks of the helical rolling of mill with a triple roll at the ends of pressurization of the package. Shown that the frontal surfaces of back pressure ensures the rational use of the base layer bimetal and improving the quality of the connection layer blanks at the expense of creating the conditions to the accumulation of compression strain in the weld zone.
