FIELD: constructional engineering.
SUBSTANCE: invention is aimed at production of high-quality rebar from standard steel. Method consists in cold deformation of hot-woven round blank within alternating deforming rollers. Required combination of strength and plastic properties of products is provided by selection of parameters of initial blank and deformation degree. Blank is deformed at the ratio of blank yield strength to finished rebar yield strength equal 0.68÷0.76, total deformation degree being regulated by mathematical relation.
EFFECT: predicted level of plastic and strength properties of steel.
