FIELD: metallurgy.
SUBSTANCE: it is received blank made of hot-rolled metal by means of drawing or calibration. In the sequel from specified blank it is formed product with usage of settlement. Total deformation ratio at drawing or calibration and total sedimitation ratio of blank across-track direction up to dimension " turnkey" it is accepted as total quantity, not exceeding 40%. Lateral dimension of hot-rolled metal is selected from condition: dk.min-K < dr.k. < dk.max+K, where: dr.k. - lateral dimension of hot-rolled metal; dk.min - minimum dimension "turnkey"; dk.max - maximum size "turnkey"; K=0.5 mm - for products with maximum size "turnkey" up to 12 mm; K=0.7 mm - for products with maximum size "turnkey" up to 27 mm; K=0.9 mm - for products with maximum size "turnkey" from above 30 mm.
EFFECT: reduction of energy capacity and labour coefficient of process, decreasing of efforts at receiving of blank and formation products of it.
