FIELD: ferrous metallurgy. SUBSTANCE: method consists in hot rolling of casting metal and cooling produced rolling stock with rate determined from formula v = t/k•Fdeg/s to a temperature determined from formula t ≅ 630 + 270/(1000), where tis temperature in the rolling end phase, F cross- section area of rolling stock (in sq.cm), and K = 15-32. EFFECT: improved consumer's characteristics due to improved plasticity of metal.

Изобретение относится к обработке металлов давлением, в частности к производству горячекатаных полос и сортового проката из сталей с содержанием углерода 0,06-0,65%. Цель изобретения - повышение потребительских свойств проката из углеродистой стали путем улучшения пластичности металла. Предлагаемый способ включает горячую прокатку из заготовки готового проката и его охлаждение и отличается тем, что охлаждение ведут со скоростью V = tk/ k• F0,37 град/с, а температуру охлаждения определяют из выражения t≅630+270/(100С)0,65 град, где tк- температура конца прокатки, град; F - площадь сечения готового проката, см2; k = 15-32.The invention relates to the processing of metals by pressure, in particular the production of hot rolled strips and long products from steels with a carbon content of 0.06-0.65%. The purpose of the invention is to increase the consumer properties of carbon steel by improving the ductility of the metal. The proposed method includes hot rolling from the finished steel billet and its cooling, and differs in that the cooling is carried out at a speed of V = t k / k • F 0.37 deg / s, and the cooling temperature is determined from the expression t≅630 + 270 / (100С ) 0.65 degrees, where t to is the temperature of the end of rolling, degrees; F is the cross-sectional area of the finished product, cm 2 ; k = 15-32.
