Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, используемого в машиностроении.The invention relates to the field of metallurgy and relates to compositions of cast iron used in mechanical engineering.
Известен чугун, включающий, мас.%: углерод 3,61-4,05; кремний 2,21-2,56; марганец 0,61-1,32; медь 0,002-0,12; алюминий 0,08-0,25; кальций 0,007-0,025; цирконий 0,02-0,32; литий 0,002-0,075; фосфор 0,11-0,45; нитриды бария 0,002-0,035; железо остальное [1].Known cast iron, including, wt.%: Carbon 3,61-4,05; silicon 2.21-2.56; manganese 0.61-1.32; copper 0.002-0.12; aluminum 0.08-0.25; calcium 0.007-0.025; zirconium 0.02-0.32; lithium 0.002-0.075; phosphorus 0.11-0.45; barium nitrides 0.002-0.035; iron the rest [1].
Задача изобретения состоит в повышении 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, медь, алюминий, кальций, цирконий, литий, фосфор, железо, дополнительно содержит кобальт при следующем соотношении компонентов, мас.%: углерод 3,6-4,0; кремний 1,6-1,8; марганец 0,7-1,1; медь 0,7-1,1; алюминий 0,3-0,4; кальций 0,007-0,011; цирконий 0,1-0,15; литий 0,002-0,003; фосфор 0,1-0,15; кобальт 0,9-1,1; железо остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, aluminum, calcium, zirconium, lithium, phosphorus, iron, additionally contains cobalt in the following ratio of components, wt.%: Carbon 3,6-4,0; silicon 1.6-1.8; manganese 0.7-1.1; copper 0.7-1.1; aluminum 0.3-0.4; calcium 0.007-0.011; zirconium 0.1-0.15; lithium 0.002-0.003; phosphorus 0.1-0.15; cobalt 0.9-1.1; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Медь способствует графитизации, увеличивает содержание в сплаве перлита, способствует увеличению прочности и пластичности сплава. Алюминий и кальций выполняют функцию раскислителей. Алюминий повышает вязкость сплава. Литий придает структуре чугуна мелкозернистость. Цирконий упрочняет границы зерен. Кобальт и фосфор способствуют увеличению твердости и прочности чугуна.In the composition of cast iron, the components manifest themselves as follows. Copper promotes graphitization, increases the content of perlite in the alloy, and increases the strength and ductility of the alloy. Aluminum and calcium act as deoxidizers. Aluminum increases the viscosity of the alloy. Lithium imparts a fine grain structure to cast iron. Zirconium strengthens grain boundaries. Cobalt and phosphorus increase the hardness and strength of cast iron.
Чугун выплавляют в электропечах и отливают 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 cast into 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.
