Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, используемого в машиностроении.The invention relates to the field of metallurgy and relates to compositions of cast iron used in mechanical engineering.
Известен чугун, включающий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; алюминий 0-0,2; кальций 0-0,2; ниобий 0-1,0; никель 0-2,5; железо - остальное [1].Known cast iron, including, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; copper 0-4.0; aluminum 0-0.2; calcium 0-0.2; niobium 0-1.0; nickel 0-2.5; 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, медь, алюминий, кальций, ниобий, никель, железо, дополнительно содержит нитриды бария при следующем соотношении компонентов, мас.%: углерод 3,0-4,0; кремний 0,5-1,0; марганец 0,5-1,0; медь 0,5-1,0; алюминий 0,1-0,2; кальций 0,003-0,007; ниобий 0,5-1,0: никель 1,0-1,5; нитриды бария 0,03-0,08; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, aluminum, calcium, niobium, nickel, iron, additionally contains barium nitrides in the following ratio of components, wt.%: Carbon 3.0-4.0; silicon 0.5-1.0; manganese 0.5-1.0; copper 0.5-1.0; aluminum 0.1-0.2; calcium 0.003-0.007; niobium 0.5-1.0: nickel 1.0-1.5; barium nitrides 0.03-0.08; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Медь способствует графитизации и резко увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Кальций и алюминий выполняют функцию раскислителей. Никель и молибден улучшают металлическую основу чугуна. Нитриды бария придают структуре чугуна мелкозернистость.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Copper promotes graphitization and dramatically increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Calcium and aluminum act as deoxidizers. Nickel and molybdenum improve the cast iron base. Barium nitrides give the structure of cast iron fine grain.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°C) 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.
