Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 3,0-3,4; кремний 1,6-2,2; марганец 0,005-0,04; ванадий 0,05-0,14; молибден 0,1-0,4, сурьма 0,05-0,1; графний 0,14-0,27, железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.0-3.4; silicon 1.6-2.2; manganese 0.005-0.04; vanadium 0.05-0.14; molybdenum 0.1-0.4, antimony 0.05-0.1; graphene 0.14-0.27, 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, молибден, сурьму, гафний, железо, дополнительно включает бор, причем компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,5; кремний 0,5-0,9; марганец 0,5-0,9; молибден 0,7-0,9;- сурьма 0,02-0,03; гафний 1,1-1,5; бор 0,02-0,03; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, antimony, hafnium, iron, additionally includes boron, and the components are in the following ratio, wt.%: Carbon 3.0-3.5; silicon 0.5-0.9; manganese 0.5-0.9; molybdenum 0.7-0.9; - antimony 0.02-0.03; hafnium 1.1-1.5; boron 0.02-0.03; 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. Марганец обеспечивает повышенную твердость чугуна. Молибден и гафний способствуют увеличению прочности чугуна. Сурьма способствует образованию мелкозернистой структуры сплава, увеличивает твердость. Бор стабилизирует карбиды, увеличивает твердость и прочность сплаваThe increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Manganese provides increased hardness of cast iron. Molybdenum and hafnium increase the strength of cast iron. Antimony promotes the formation of a fine-grained structure of the alloy, increases hardness. Boron stabilizes carbides, increases the hardness and strength of the alloy
Чугун выплавляют в электропечах и отливают в горячие (~400°C) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°C и отпуску при температуре 350-450°C.Cast iron is smelted in electric furnaces and cast into hot (~ 400 ° C) metal molds coated with refractory clay. The castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
