Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, используемого для изготовления деталей, подвергающихся повышенным статическим нагрузкам.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron used for the manufacture of parts subjected to high static loads.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,5-3,5; марганец 0,2-1,5; хром 0-3,0; магний 0,02-0,1; алюминий 0-2,0; молибден 0-2,0; бор 0-2,0; титан 0-2,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.5-3.5; manganese 0.2-1.5; chrome 0-3.0; magnesium 0.02-0.1; aluminum 0-2.0; molybdenum 0-2.0; boron 0-2.0; titanium 0-2.0; iron - the rest [1].
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, хром, магний, алюминий, молибден, бор, титан, железо, дополнительно содержит медь при следующем соотношении компонентов, мас.%; углерод 3,0-3,5; кремний 1,0-1,5; марганец 1,0-1,5; хром 0,1-0,3; магний 0,005-0,01; алюминий 0,1-0,3; молибден 3,5-4,5; бор 0,03-0,05; титан 0,1-0,2; медь 0,8-1,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, magnesium, aluminum, molybdenum, boron, titanium, iron, additionally contains copper in the following ratio of components, wt.%; carbon 3.0-3.5; silicon 1.0-1.5; manganese 1.0-1.5; chrome 0.1-0.3; magnesium 0.005-0.01; aluminum 0.1-0.3; molybdenum 3.5-4.5; boron 0.03-0.05; titanium 0.1-0.2; copper 0.8-1.2; iron is the rest.
В таблице приведены примеры составов чугуна.The table shows examples of cast iron compositions.
Повышение прочности чугуна достигается за счет образования мелкозернистой перлитной структуры.An increase in the strength of cast iron is achieved through the formation of a fine-grained pearlite structure.
Совместное присутствие хрома и молибдена способствует выделению перлита. Марганец тормозит выделение графита и, введенный совместно с титаном, придает мелкозернистость структуре сплава. Бор стабилизирует карбиды, алюминий и магний выполняют функцию раскислителей. Алюминий выполняет функцию раскислителей.The combined presence of chromium and molybdenum contributes to the release of perlite. Manganese inhibits the release of graphite and, introduced together with titanium, imparts a fine-grained alloy structure. Boron stabilizes carbides, aluminum and magnesium act as deoxidizers. Aluminum acts as a deoxidizing agent.
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.
