Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in mechanical 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 кальций, литий, бор, причем компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,4-0,8; алюминий 0,04-0,08; медь 2,2-2,6; ванадий 0,6-0,8; гафний 0,1-0,12; кальций 0,002-0,004; литий 0,001-0,0015; бор 0,1-0,15; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, vanadium, hafnium, iron, additionally includes calcium, lithium, boron, 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 0.04-0.08; copper 2.2-2.6; vanadium 0.6-0.8; hafnium 0.1-0.12; calcium 0.002-0.004; lithium 0.001-0.0015; boron 0.1-0.15; 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 улучшает металлическую основу сплава, повышает его вязкость. Медь увеличивает прочность чугуна. Алюминий, кальций, литий выполняют функцию раскислителей, обеспечивают измельчение зерна. Бор стабилизирует карбиды. Бор и гафний способствуют увеличению прочности и твердости чугуна.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Vanadium improves the metal base of the alloy, increases its viscosity. Copper increases the strength of cast iron. Aluminum, calcium, lithium perform the function of deoxidizing agents, provide grain grinding. Boron stabilizes carbides. Boron and hafnium increase the strength and hardness 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.
