description FIELD: plastic metal working, namely extruding ingots, mainly with lengthwise laminarity. SUBSTANCE: method comprises steps of assembling ingots by placing one blank inside another, making outer blank of more ductile material than another, mutually fixing blanks, heating ingot, placing it onto needle and extruding through cone die due to arranging it in container and applying axial compression effort to its end. Ingot is assembled at simultaneously forming on its outer surface annular protrusions, arranging assembled blanks in fitting provided with annular recesses and applying compression effort to ends of outer blank. Said annular recesses of fitting are filled by material of outer blank. Then said blanks are mutually fixed by moving initially inner blank relative to outer one at shaping slope at side opposite relative to effort applying side. The blanks are moved together relative to said annular protrusions. When ingot is placed onto needle said slope is arranged at side of cone die. EFFECT: enhanced efficiency. 9 dwgd
