Abstract
Description
Изобретение относится к области металлургии и производству сталей, которые могут быть использованы в транспортном машиностроении.The invention relates to the field of metallurgy and the production of steel, which can be used in transport engineering.
Известна сталь, содержащая углерод 0-1,0; кремний 0-3,0; марганец 0-2,0; ванадий 0-1,0; алюминий 0-2,0; титан 0-5,0; ниобий 0-5,0; цирконий 0-0,3; молибден 0-10,0; медь 0-5,0; железо - остальное [1].Known steel containing carbon 0-1.0; silicon 0-3.0; manganese 0-2.0; vanadium 0-1.0; aluminum 0-2.0; titanium 0-5.0; niobium 0-5.0; zirconium 0-0.3; molybdenum 0-10.0; copper 0-5.0; iron - the rest [1].
Задача изобретения состоит в повышении хладостойкости стали.The objective of the invention is to improve the cold resistance of steel.
Технический результат достигается тем, что конструкционная сталь, содержащая углерод, кремний, марганец, ванадий, алюминий, титан, ниобий, цирконий, молибден, медь, железо, дополнительно включает барий и кальций при следующем соотношении компонентов, мас.%: углерод 0,05-0,1; кремний 0,1-0,15; марганец 0,4-0,8; ванадий 0,4-0,8; алюминий 0,1-0,2; титан 0,4-0,8; ниобий 0,2-0,3; цирконий 0,2-0,3; молибден 1,8-2,2; медь 0,5-1,0; барий 0,004-0,008; кальций 0,004-0,008; железо - остальное.The technical result is achieved by the fact that structural steel containing carbon, silicon, manganese, vanadium, aluminum, titanium, niobium, zirconium, molybdenum, copper, iron, additionally includes barium and calcium in the following ratio, wt.%: Carbon 0.05 -0.1; silicon 0.1-0.15; manganese 0.4-0.8; vanadium 0.4-0.8; aluminum 0.1-0.2; titanium 0.4-0.8; niobium 0.2-0.3; zirconium 0.2-0.3; molybdenum 1.8-2.2; copper 0.5-1.0; barium 0.004-0.008; calcium 0.004-0.008; iron is the rest.
В таблице приведены составы конструкционной стали.The table shows the composition of structural steel.
В составе стали компоненты проявляются следующим образом. Ниобий и молибден упрочняют твердый раствор. Медь увеличивает прочностные и пластические свойства стали. Алюминий и ванадий повышают вязкость стали. Барий и кальций выполняют функцию раскислителей. Титан способствует измельчению зерна. Цирконий упрочняет границы зерен.In the composition of the steel components are manifested as follows. Niobium and molybdenum strengthen the solid solution. Copper increases the strength and plastic properties of steel. Aluminum and vanadium increase the viscosity of steel. Barium and calcium act as deoxidizers. Titanium helps to chop grain. Zirconium strengthens grain boundaries.
Сталь может быть выплавлена кислым конверторным способом на кислородном дутье. Основной исходный материал - бессемеровский чугун и стальной лом. Термическая обработка стали включает закалку при температуре 650°С в масло и отпуск при температуре 650°С.Steel can be melted using an acidic converter method using oxygen blasting. The main source material is Bessemer cast iron and steel scrap. Heat treatment of steel includes quenching at a temperature of 650 ° C in oil and tempering at a temperature of 650 ° C.
