FIELD: plastic metal working, possibly manufacture of cold rolled strip steel. ^ SUBSTANCE: method comprises steps of rapidly reducing strip between rolls at predetermined value of percentage deformation epsilon. Said value is set for strips with thickness 0.5 - 2.5 mm depending upon strength properties of steel and carbon content in it equal to epsilon1 = 2.6 -10[C],% at 345 > sigmat >= 295MPa; epsilon2 = 3.75 - 15[C],% at sigmat >= 345 MPa where [C] -carbon content in steel, mass %. ^ EFFECT: less loss of yield, possibility for providing optimal relation of strength and plastic properties of articles. ^ 2 ex |
