METHOD FOR PRODUCTION OF MULTILAYER BILLETS BY ROLLING Russian patent published in 1994 - IPC

Abstract RU 2006354 C1

FIELD: metallurgy; mechanical engineering. SUBSTANCE: method includes assembling of layers with prepared surfaces followed by step-wise rolling. After the total deformation rate in the area of squeezing zone multiple of the adjustable feed rate reaches 70- 80% , the billet is squeezed in accordance with the hyperbolic law. EFFECT: enabled production of billets with three and more layers; enabled production of composite billets containing powders. 3 dwg
