FIELD: metallurgy. SUBSTANCE: method involves introducing into crystallizer two tapes of heterogeneous metals having different melting temperatures along inclined walls; squeezing tapes; gauging surface of bimetallic blank and drawing it; imparting reciprocating motion to pair of vertical walls in crystallizer and rotational motion to pair of inclined walls, with vertical walls being preheated. Contact squeezing is provided over part of surfaces of tapes introduced into crystallizer. Vertical walls are heated to t= (l-1.05)t(m), where t(m) is melting temperature for metal of one type, which is lesser than that of metal of other tape. Apparatus has water cooled crystallizer equipped with pair of vertical walls mounted for reciprocation and pair of inclined walls mounted for rotation, and cylinders with tapes. Vertical walls are made in the form of heating tubes. Longitudinal beads of "a1" height and "b1" width are formed on tape working surfaces, with values of said characteristics being correlated to total thickness "a2" and width "b2" as a1/a2=0.2-0.8; b1/b2=0.05-0.3. EFFECT: enhanced reliability in operation of apparatus and improved strength of bimetallic hollow blanks. 2 dwg
