Abstract

FIELD: production of hot- rolled section steel. SUBSTANCE: proposed rolling process includes hot deformation of billet in intermediate and finish passages with reduction of metal in mutually perpendicular directions in adjacent passages. In agreement with process value of relative deformation in each passage is determined from expression ε= (0,79...0,82)(f/F), where F and f are areas of cross-sections of initial billet and finished profile. EFFECT: improved user's properties of rolled stock and diminished labour input in its production.

Изобретение относится к технологии производства горячекатаной сортовой стали. Задача изобретения: улучшение потребительских свойств проката и снижение трудозатрат при его производстве. Предлагаемый способ прокатки включает горячую деформацию заготовки в промежуточных и чистовых проходах с обжатием металла во взаимно - перпендикулярных направлениях в смежных проходах и отличается тем, что величину относительной деформации в каждом из проходов определяют из выражения, указанного в описании.The invention relates to a technology for the production of hot-rolled section steel. The objective of the invention: improving the consumer properties of rolled products and reducing labor costs in its production. The proposed rolling method includes hot deformation of the workpiece in intermediate and finishing passes with metal compression in mutually perpendicular directions in adjacent passes and differs in that the relative strain in each of the passes is determined from the expression specified in the description.
