Abstract
FIELD: plastic metal working, namely methods of extruding built-up-thickness ingots for making tubes with clad tubes. SUBSTANCE: method of extruding ingots, mainly ingots having longitudinal laminarity due to using two billets arranged one to another with outer billet made of higher strength material than inner billet, comprises steps of heating ingot, placing it onto needle for subsequent extrusion through cone die by arranging it in container and applying axial compression afford to end of said ingot. Novelty is formation of ingot from two different-size billets with cavity in one end of ingot. When ingot is placed onto needle said cavity is arranged at side of extrusion die. Extrusion process is performed at variable deformation rate. Initially axial compression effort is applied only to billet made of higher strength material for subsequent by welding deformed materials and extruding tube from said higher strength material. Then combined deformation of billets is realized with rate exceeding initial one. EFFECT: enhanced efficiency, high quality of clad tubes. 1 cl, 7 dwg
