Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам стали, которая может быть использована в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of steel, which can be used in mechanical engineering.
Известна сталь, содержащая, мас. %: углерод 0,23-0,3; кремний 0,17-0,37; марганец 1,1-1,6; хром 0,6-0,9; титан 0,005-0,01; церий 0,002-0,01; азот 0,002-0,008; железо - остальное [1].Known steel containing, by weight. %: carbon 0.23-0.3; silicon 0.17-0.37; manganese 1.1-1.6; chrome 0.6-0.9; titanium 0.005-0.01; cerium 0.002-0.01; nitrogen 0.002-0.008; iron - the rest [1].
Задачей изобретения является повышение прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, титан, церий, железо, дополнительно содержит эрбий, рений, молибден и бор, при следующем соотношении компонентов, мас. %: углерод 0,9-1,1; кремний 0,05-0,15; марганец 1,1-1,6; хром 0,5-0,9; титан 0,3-0,5; церий 0,05-0,15; эрбий 0,8-1,2; рений 3,0-3,4; молибден 0,25-0,35; бор 0,1-0,2; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, titanium, cerium, iron, additionally contains erbium, rhenium, molybdenum and boron, in the following ratio of components, wt. %: carbon 0.9-1.1; silicon 0.05-0.15; manganese 1.1-1.6; chrome 0.5-0.9; titanium 0.3-0.5; cerium 0.05-0.15; erbium 0.8-1.2; rhenium 3.0-3.4; molybdenum 0.25-0.35; boron 0.1-0.2; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Повышение прочности стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром, титан, рений, эрбий, церий, молибден, бор повышают прочность стали. Бор стабилизирует карбиды. Рений препятствует возникновению и развитию трещин при механических нагрузках.Increasing the strength of steel is achieved due to the complex effect of the components that make up its composition. Chrome, titanium, rhenium, erbium, cerium, molybdenum, boron increase the strength of steel. Boron stabilizes carbides. Rhenium prevents the occurrence and development of cracks under mechanical stress.
Сталь может быть выплавлена в электропечах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта. Сталь подлежит термической обработке по режиму: закалка при температуре 780-800°С в масло с последующим отпуском при температуре 160-220°С.Steel can be smelted in electric furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge. Steel is subject to heat treatment according to the regime: quenching at a temperature of 780-800 ° C in oil, followed by tempering at a temperature of 160-220 ° C.
