Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; никель 0,01-5,0; титан 0,01-0,15; молибден 0,01-2,0; тантал 0,001-0,1; бор 0,01-0,1; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; nickel 0.01-5.0; titanium 0.01-0.15; molybdenum 0.01-2.0; tantalum 0.001-0.1; boron 0.01-0.1; 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, никель, титан, молибден, тантал, бор, железо, дополнительно содержит магний при следующем соотношении компонентов, мас.%: углерод 2,6-3,2; кремний 1,6-2,0; марганец 0,6-1,0; никель 1,5-2,5; титан 0,1-0,3; молибден 1,6-2,2; тантал 0,1-0,3; бор 0,08-0,12; магний 0,01-0,03; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, nickel, titanium, molybdenum, tantalum, boron, iron, additionally contains magnesium in the following ratio of components, wt.%: Carbon 2,6-3,2; silicon 1.6-2.0; manganese 0.6-1.0; nickel 1.5-2.5; titanium 0.1-0.3; molybdenum 1.6-2.2; tantalum 0.1-0.3; boron 0.08-0.12; magnesium 0.01-0.03; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Совместное присутствие молибдена и никеля позволяет получить чугун с игольчатой структурой. Бор стабилизирует карбиды, никель и тантал упрочняют твердый раствор. Магний выполняет функцию раскислителя. Присутствие титана способствует измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. The combined presence of molybdenum and nickel allows you to get cast iron with a needle structure. Boron stabilizes carbides, nickel and tantalum strengthen the solid solution. Magnesium acts as a deoxidizer. The presence of titanium contributes to grain refinement.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay.
Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
