Abstract
Description
Изобретение относится к области металлургий, в частности к составам серого чугуна, который может быть использован в транспортном машиностроении.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in transport engineering.
Известен чугун, содержащий, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,4-0,8; алюминий 0,1-0,2; медь 1,6-2,0; ванадий 1,0-1,6; гафний 0,3-0,7; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.0-3.4; silicon 0.8-1.2; manganese 0.4-0.8; aluminum 0.1-0.2; copper 1.6-2.0; vanadium 1.0-1.6; hafnium 0.3-0.7; 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, алюминий, медь, ванадий, гафний, железо, дополнительно включает кобальт, никель, олово, причем компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,4-0,8; алюминий 0,05-0,07; медь 2,2-2,6; ванадий 0,2-0,3; гафний 0,1-0,2; кобальт 0,6-1,0; никель 0,6-1,0; олово 0,001-0,003; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, vanadium, hafnium, iron, additionally includes cobalt, nickel, tin, and the components are in the following ratio, wt.%: Carbon 3.0-3 ,four; silicon 0.8-1.2; manganese 0.4-0.8; aluminum 0.05-0.07; copper 2.2-2.6; vanadium 0.2-0.3; hafnium 0.1-0.2; cobalt 0.6-1.0; nickel 0.6-1.0; tin 0.001-0.003; 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, никель, кобальт, гафний, медь повышают прочность сплава. Гафний способствует увеличению твердости чугуна. Ванадий увеличивает вязкость чугуна, препятствует возникновению трещин в отливках. Алюминий выполняет функцию раскислителя, а олово обеспечивает измельчение зерна.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Vanadium, nickel, cobalt, hafnium, copper increase the strength of the alloy. Hafnium increases the hardness of cast iron. Vanadium increases the viscosity of cast iron, prevents the occurrence of cracks in the castings. Aluminum acts as a deoxidizing agent, and tin provides grain refinement.
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.
