Abstract
Description
Изобретение относится к области черной металлургии и касается составов чугуна, который может быть использован для изготовления изделий, работающих в условиях трения и повышенного износа.The invention relates to the field of ferrous metallurgy and relates to compositions of cast iron, which can be used for the manufacture of products operating in conditions of friction and increased wear.
Известен серый чугун, содержащий, мас.%: углерод 3,2-3,6; кремний 0,5-0,7; марганец 1,3-1,5; алюминий 0,3-1,3; молибден 0,2-0,3; фосфор до 0,1; железо - остальное [1].Known gray cast iron, containing, wt.%: Carbon 3.2-3.6; silicon 0.5-0.7; manganese 1.3-1.5; aluminum 0.3-1.3; molybdenum 0.2-0.3; phosphorus up to 0.1; iron - the rest [1].
Задача изобретения состоит в повышении износостойкости чугуна.The objective of the invention is to increase the wear resistance of cast iron.
Технический результат достигается тем, что серый чугун, содержащий углерод, кремний, марганец, алюминий, молибден, железо, дополнительно включает бор, вольфрам и рений при следующем соотношении компонентов, мас.%: углерод 3,2-3,6; кремний 0,2-0,3; марганец 1,3-1,7; алюминий 0,1-02; молибден 0,2-0,3; бор 0,02-0,04; вольфрам 0,9-1,3; рений 0,7-1,1; железо - остальное.The technical result is achieved by the fact that gray cast iron containing carbon, silicon, manganese, aluminum, molybdenum, iron, additionally includes boron, tungsten and rhenium in the following ratio of components, wt.%: Carbon 3,2-3,6; silicon 0.2-0.3; manganese 1.3-1.7; aluminum 0.1-02; molybdenum 0.2-0.3; boron 0.02-0.04; tungsten 0.9-1.3; rhenium 0.7-1.1; iron is the rest.
В таблице приведены составы серого чугуна.The table shows the compositions of gray cast iron.
За 1 отн. ед. принят износ при сухом трении известного чугуна [1] в условиях удельного давления до 100 кгс/см2, скорости скольжения до 5,7 м/с, контртело - чугун серый модифицированный (МСЧ 28-48).For 1 rel. units dry friction wear of known cast iron [1] under specific pressure up to 100 kgf / cm 2 , sliding speed up to 5.7 m / s, counterbody - gray cast iron modified (MSC 28-48) was adopted.
Повышение износостойкости чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Марганец обеспечивает повышенную твердость чугуна. Молибден, вольфрам и рений упрочняют твердый раствор. Бор стабилизирует карбиды. Алюминий выполняет функцию раскислителя, обеспечивает мелкозернистость структуры чугуна.The increase in wear resistance 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, tungsten and rhenium strengthen the solid solution. Boron stabilizes carbides. Aluminum performs the function of a deoxidizer, provides a fine-grained structure of cast iron.
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.
