Description
Изобретение относитс к металлургии. в частности к составу стали, используемой дл изготовлени трубной заготовки и бесшовных труб и вл етс усовершенствованием изобретени по авт.св. № 722986.The invention relates to metallurgy. in particular, to the composition of the steel used for the manufacture of billet and seamless pipes, and is an improvement of the invention on the author. No. 722986.
Цель изобретени - повышение выхода годного при производстве трубной заготовки и высокопрочных бесшовных труб за счет повышени технологической пластичности .The purpose of the invention is to increase the yield in the production of tubular billet and high-strength seamless pipes by increasing the technological plasticity.
Результаты экспериментов по выбору оптимальных пределов произведени % ванади (% углерода-i-(% марганца /4). а также содержани алюмини приведены в таблице.The results of experiments on the choice of the optimal product limits% vanadium (% carbon-i - (% manganese / 4). As well as the aluminum content are given in the table.
Количество вводимого в сталь ванади определ етс D зависимости от содержани в ней углерода и марганца.The amount of vanadium introduced into steel is determined by D depending on the content of carbon and manganese in it.
Использование изобретени позволит обеспечить высокое качество металлопродукции .The use of the invention will ensure high quality metal products.
