Abstract
Description
Изобретение относится к области металлургии, в частности к составам сталей, которые могут быть использованы для изготовления отливок сложных конфигураций.The invention relates to the field of metallurgy, in particular to compositions of steels that can be used for the manufacture of castings of complex configurations.
Известна сталь, содержащая, мас.%: углерод 0,1-0,19; кремний 0,2-0,42; марганец 0,35-0,75; ванадий 0,04-0,15; азот 0,008-0,03; кальций 0,001-0,009; алюминий 0,01-0,03; железо остальное [1]. Жидкотекучесть такой стали составляет 220-260 мм.Known steel containing, wt.%: Carbon 0.1-0.19; silicon 0.2-0.42; manganese 0.35-0.75; vanadium 0.04-0.15; nitrogen 0.008-0.03; calcium 0.001-0.009; aluminum 0.01-0.03; iron the rest [1]. The fluidity of such steel is 220-260 mm.
Задача изобретения состоит в повышении жидкотекучести стали.The objective of the invention is to increase the fluidity of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, ванадий, азот, кальций, алюминий, железо, дополнительно включает фосфор и бор при следующем соотношении компонентов, мас.%: углерод 0,1-0,15; кремний 0,2-0,3; марганец 0,4-0,7; ванадий 0,1-0,2; азот 0,02-0,03; кальций 0,006-0,01; алюминий 0,04-0,06; фосфор 0,1-0,15; бор 0,4-0,5; железо остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, vanadium, nitrogen, calcium, aluminum, iron, further includes phosphorus and boron in the following ratio of components, wt.%: Carbon 0.1-0.15; silicon 0.2-0.3; manganese 0.4-0.7; vanadium 0.1-0.2; nitrogen 0.02-0.03; calcium 0.006-0.01; aluminum 0.04-0.06; phosphorus 0.1-0.15; boron 0.4-0.5; iron the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Бор стабилизирует карбиды. Кальций и алюминий выполняют функцию раскислителей. Фосфор образует легкоплавкую эвтектику, повышает механические свойства стали. В химически связанном состоянии с алюминием и ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали.In the steel composition, the components manifest themselves as follows. Boron stabilizes carbides. Calcium and aluminum act as deoxidizers. Phosphorus forms a fusible eutectic, increases the mechanical properties of steel. In a chemically bound state with aluminum and vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel.
Сталь может быть выплавлена мартеновским способом Исходный материал для выплавки стали - передельный 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 in the open-hearth method. The starting material for steelmaking is pig 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.
