Abstract
Description
Изобретение относится к области металлургии, а именно к составам серого чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, and in particular to compositions of gray cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 3,0-3,6; кремний 1,9-2,2; марганец 0,4-0,8; магний 0,03-0,07; алюминий 0,5-1,0; церий 0,01-0,05; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.0-3.6; silicon 1.9-2.2; manganese 0.4-0.8; magnesium 0.03-0.07; aluminum 0.5-1.0; cerium 0.01-0.05; iron - the rest [1].
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,5-3,5; марганец 0,2-1,5; магний 0,02-0,1; алюминий 0-2,0; бор 0-2,0; ванадий 0-2,0; железо - остальное [2|.Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.5-3.5; manganese 0.2-1.5; magnesium 0.02-0.1; aluminum 0-2.0; boron 0-2.0; vanadium 0-2.0; iron - the rest [2 |.
Задачей изобретения является повышение 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, магний, алюминий, бор, ванадий, железо, дополнительно содержит церий и медь при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 1,8-2,2; марганец 0,4-0,8; магний 0,003-0,008; алюминий 0,1-0,3; церий 0,05-0,1; бор 0,01-0,03; ванадий 0,3-0,5; медь 0,8-1,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, aluminum, boron, vanadium, iron, additionally contains cerium and copper in the following ratio of components, wt.%: Carbon 3.0-3.5; silicon 1.8-2.2; manganese 0.4-0.8; magnesium 0.003-0.008; aluminum 0.1-0.3; cerium 0.05-0.1; boron 0.01-0.03; vanadium 0.3-0.5; copper 0.8-1.2; 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. Ванадий упрочняет твердый раствор. Медь способствует графитизации и резко увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Магний и церий выполняют функцию раскислителя. Бор стабилизирует карбиды. Алюминий придает структуре мелкозернистость.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Vanadium strengthens the solid solution. Copper promotes graphitization and dramatically increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Magnesium and cerium act as a deoxidizing agent. Boron stabilizes carbides. Aluminum gives the structure a fine grain.
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.
