FIELD: metallurgy. SUBSTANCE: method involves atomizing liquid metal in crystallizer; supplying inert gas; squeezing billet under process; gaging billet surface and providing continuous drawing; simultaneously supplying mixtures of two melts of two metals into center of crystallizer by means of two pouring vessels disposed one above the other; squeezing formable billet. First pouring vessel is filled with melt having lower crystallization temperature than melt poured into second pouring vessel. Second pouring vessel has stops with through openings. Ratio of melt mixture M1 with lower crystallization temperature and melt mixture M2 with higher crystallization temperature is M1=(0.01-0.25) M2. Crystallizer has first pair of reciprocating faces and opposite second pair of rotating faces. Upper part of crystallizer is made widened and inclined with respect to vertical plane. Lower pouring vessel has immersion cup with opposed through openings in its lower side wall. Opening axes are extending in parallel with crystallizer faces with widened portion in their upper part and make angle of 5-10 deg with respect to horizontal plane. Inner surface of through openings is configured in accordance with law: y=0.5 •xm, where m=2,3,4. Method allows billets of random profile and thickness with continuous surface to be produced from two melts. EFFECT: increased efficiency in producing billets with surface of improved quality and inner structure, enhanced reliability in operation of apparatus and improved maintenance of equipment. 3 cl, 2 dwg
