Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован в общем машиностроении.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used in general engineering.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-2,5; алюминий 0-0,2; ниобий 0-1,0; бор 0-1,0; медь 0-4,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-2.5; aluminum 0-0.2; niobium 0-1.0; boron 0-1.0; copper 0-4.0; iron - the rest [1].
Задача изобретения состоит в повышении прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, ниобий, бор, медь, железо, дополнительно включает азот при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,0-1,5; марганец 0,5-1,0; алюминий 0,1-0,2; ниобий 1,0-1,5; бор 0,03-0,05; медь 0,8-1,2; азот 0,1-0,15; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, niobium, boron, copper, iron, additionally includes nitrogen in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 1.0-1.5; manganese 0.5-1.0; aluminum 0.1-0.2; niobium 1.0-1.5; boron 0.03-0.05; copper 0.8-1.2; nitrogen 0.1-0.15; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Медь улучшает металлическую основу чугуна, препятствует развитию трещин. Бор стабилизирует карбиды. Алюминий раскисляет чугун. Ниобий упрочняет твердый раствор. В химически связанном состоянии с алюминием и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства сплава.The components present in the composition of cast iron manifest themselves as follows. Copper improves the metal base of cast iron, prevents the development of cracks. Boron stabilizes carbides. Aluminum deoxidizes cast iron. Niobium strengthens the solid solution. In a chemically bound state with aluminum and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of the alloy.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
