Abstract

FIELD: metallurgy, production of special-purpose rolled products using thermomechanical method of treatment in particular. SUBSTANCE: aim is to increase indexes of low-temperature impact ductility and cold-resistance with maintaining previous strength of metal. Method of sheet rolled products production provides for smelting of definite chemical composition steel, treatment of metal in ladle, casting in ingot moulds at speed of 0.1 - 0.5 t/s, austenitizing under temperature of 1200 - 1350 C, rolling in blooming mill with relative cogging of 33 - 82 % preliminary deformation with relative cogging of 6 - 90 %, final deformation with relative cogging of 15 - 97 %, thermal treatment of rolled products and its final cooling to temperature of environment. Versions of thermal treatment and cooling of rolled products are described. EFFECT: increased indexes of low-temperature impact ductility and cold-resistance with maintaining previous strength of metal. 9 cl

Изобретение относится к металлургии, конкретнее к производству проката ответственного назначения методом термомеханической обработки. Цель изобретения заключается в повышении показателей низкотемпературной ударной вязкости и хладостойкости при сохранении той же прочности металла. Способ производства листового проката включает выплавку стали определенного химического состава, обработку металла в ковше, разливку в изложницы со скоростью 0,1 - 0,5 т/с, аустенизацию при температуре 1200 - 1350oС, прокатку на блюминге с относительным обжатием 33 - 82%, предварительную деформацию с относительным обжатием 6 - 95%, окончательную деформацию с относительным обжатием 15 - 97%, термообработку проката и его окончательное охлаждение до температуры окружающей среды. Предлагаются варианты термообработки и охлаждения проката.The invention relates to metallurgy, and more particularly to the production of critical rolled products by thermomechanical processing. The purpose of the invention is to increase the performance of low temperature toughness and cold resistance while maintaining the same strength of the metal. A method for the production of sheet metal includes steelmaking of a certain chemical composition, metal processing in a ladle, casting into molds at a speed of 0.1 - 0.5 t / s, austenization at a temperature of 1200 - 1350 o C, blooming rolling with a relative compression of 33 - 82 %, preliminary deformation with relative compression of 6 - 95%, final deformation with relative compression of 15 - 97%, heat treatment of rolled products and its final cooling to ambient temperature. Options for heat treatment and cooling of rolled products are offered.
