Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron used in mechanical engineering.
Известен чугун следующего состава, мас.%: углерод 3,2-3,9; кремний 1,25-1,7; марганец 0,005-0,03; фосфор 0,15-0,6; церий 0,002-0,006; кальций 0,02-0,05; титан 0,001-0,1; бор 0,002-0,008; медь 0,8-1,2; алюминий 0,005-0,01; железо - остальное [1]. Предел прочности такого чугуна при растяжении составляет 725-730 МПа.Known cast iron of the following composition, wt.%: Carbon 3.2-3.9; silicon 1.25-1.7; manganese 0.005-0.03; phosphorus 0.15-0.6; cerium 0.002-0.006; calcium 0.02-0.05; titanium 0.001-0.1; boron 0.002-0.008; copper 0.8-1.2; aluminum 0.005-0.01; iron - the rest [1]. The tensile strength of such cast iron is 725-730 MPa.
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, фосфор, церий, кальций, титан, бор, медь, алюминий, железо, дополнительно содержит никель при следующем соотношении компонентов, мас.%: углерод 3,0-4,0; кремний 1,0-1,5; марганец 0,8-1,2; фосфор 0,1-0,2; церий 0,03-0,05; кальций 0,01-0,02; титан 0,1-0,3; бор 0,1-0,2; медь 0,8-1,2; алюминий 0,1-0,2; никель 1,0-2,0; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, phosphorus, cerium, calcium, titanium, boron, copper, aluminum, iron, additionally contains nickel in the following ratio of components, wt.%: Carbon 3.0-4, 0; silicon 1.0-1.5; manganese 0.8-1.2; phosphorus 0.1-0.2; cerium 0.03-0.05; calcium 0.01-0.02; titanium 0.1-0.3; boron 0.1-0.2; copper 0.8-1.2; aluminum 0.1-0.2; nickel 1.0-2.0; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышенная прочность чугуна на удар достигается за счет комплексного влияния компонентов, входящих в его состав. Никель упрочняет твердый состав. Медь увеличивает содержание в сплаве перлита. Бор стабилизирует карбиды. Фосфор образует легкоплавкую эвтектику, состоящую из аустенита и фосфида железа. Алюминий, кальций, церий выполняют функцию раскислителей. Титан способствует измельчению зерна.The increased impact strength of cast iron is achieved due to the complex effect of the components included in its composition. Nickel strengthens the solid composition. Copper increases the content of perlite in the alloy. Boron stabilizes carbides. Phosphorus forms a low-melting eutectic consisting of austenite and iron phosphide. Aluminum, calcium, cerium act as deoxidizers. Titanium helps to chop grain.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is melted in electric furnaces and cast in molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
