Abstract
Description
Изобретешь относится к области черной металлургии, а именно к составам сталей, которые могут быть использованы для изготовления деталей машин, работающих в условиях трения.The invention relates to the field of ferrous metallurgy, namely to the compositions of steels that can be used for the manufacture of machine parts operating in friction conditions.
Известна сталь, содержащая следующие компоненты, мас.%: углерод 0,35-1,2; кремний 0,1-3,0; марганец 0,1-2,0; хром <4,5; никель <4,5; кальций <0,05; фосфор <0,2; сурьма <0,15; бор <0,01; железо - остальное [1]. Задачей изобретения является повышение износостойкости стали.Known steel containing the following components, wt.%: Carbon 0.35-1.2; silicon 0.1-3.0; manganese 0.1-2.0; chrome <4.5; nickel <4.5; calcium <0.05; phosphorus <0.2; antimony <0.15; boron <0.01; iron - the rest [1]. The objective of the invention is to increase the wear resistance of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, никель, кальций, фосфор, сурьму, бор, железо, дополнительно включает теллур и самарий при следующем соотношении компонентов, мас.%: углерод 0,9-1,2; кремний 0,9-1,2; марганец 2,3-2,7; хром 4,0-4,6; никель 1,3-1,7; кальций 0,001-0,002; фосфор 0,26-0,32; сурьма 0,2-0,24; бор 0,26-0,32; теллур 0,0002-0,0003; самарий 0,1-0,14; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, nickel, calcium, phosphorus, antimony, boron, iron, additionally includes tellurium and samarium in the following ratio of components, wt.%: Carbon 0.9-1, 2; silicon 0.9-1.2; manganese 2.3-2.7; chrome 4.0-4.6; nickel 1.3-1.7; calcium 0.001-0.002; phosphorus 0.26-0.32; antimony 0.2-0.24; boron 0.26-0.32; tellurium 0.0002-0.0003; samarium 0.1-0.14; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Повышение износостойкости стали обусловлено комплексным влиянием компонентов, входящих в ее состав. Хром, никель, марганец, теллур и бор повышают твердость сплава. Хром и теллур стабилизируют карбиды. Кальций и самарий выполняют функцию раскислителей. Фосфор образует легкоплавкую эвтектику, ее твердые участки в материале мелкозернистого строения способствуют повышению износостойкости. Кремний упрочняет границы зерен. Сурьма препятствует образованию заусениц.The increase in wear resistance of steel is due to the complex effect of the components that make up its composition. Chrome, nickel, manganese, tellurium and boron increase the hardness of the alloy. Chromium and tellurium stabilize carbides. Calcium and samarium act as deoxidizers. Phosphorus forms a low-melting eutectic, its hard sections in the fine-grained material contribute to increased wear resistance. Silicon strengthens grain boundaries. Antimony prevents the formation of barbs.
Сталь может быть выплавлена кислым конвертерным способом на кислородном дутье. Основной исходный материал - бессемеровский чугун и стальной лом. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be melted using an acidic converter using oxygen blasting. The main source material is Bessemer cast iron and steel scrap. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
