v = k2 H/δ2,
где k - константа, δ - толщина корочки плакирующего слоя перед обжатием, H - высота расплава плакирующего металла в кристаллизаторе. Прохождение основной твердой полосы через расплав металла способствует оплавлению и удалению окисной пленки, отсутствие окисной пленки на металле плакирующего слоя и обжатия бойками биметаллического слитка обеспечивает надежное сваривание слоев, получение мелкозернистой и однородной структуры металла плакирующего слоя, хорошее качество поверхности и точность биметаллической полосы.The invention relates to metallurgy, namely to the continuous casting of metal. The present invention is the reduction of the method of obtaining a bimetalic strip and improve its quality. Existing methods of continuous casting of bimetallic ingot allow to obtain high quality bimetal and lead to high capital and operating costs. In the proposed method for producing a bimetallic strip, including feeding the metal of a cladding layer in a liquid state and pulling a bimetallic strip into a mold, pass a strip of 2nd metal in a solid state, connect it with a crystallizing crust of the cladding metal by crimping the split crystallizer. Moreover, the bimetallic strip is carried out with a speed of
v = k 2 H / δ 2 ,
where k is a constant, δ is the thickness of the crust of the cladding layer before compression, H is the height of the melt of the cladding metal in the mold. The passage of the main solid strip through the molten metal contributes to the melting and removal of the oxide film, the absence of an oxide film on the metal of the cladding layer and the stripping of the bimetallic ingot by the strikes ensures reliable welding of the layers, obtaining a fine-grained and uniform metal structure of the cladding layer, good surface quality and accuracy of the bimetallic strip.
