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 2,7-4,0; кремний 0,5-3,5; марганец 0,2-2,0; магний 0,001-0,5; алюминий 0,001-0,5; никель 2,5-7,0; ванадий 0,2-1,8; бор 0,001-0,5; кобальт 0,001-0,5; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.7-4.0; silicon 0.5-3.5; manganese 0.2-2.0; magnesium 0.001-0.5; aluminum 0.001-0.5; nickel 2.5-7.0; vanadium 0.2-1.8; boron 0.001-0.5; cobalt 0.001-0.5; 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, магний, алюминий, никель, ванадий, бор, кобальт, железо, дополнительно содержит селен при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,8-2,2; марганец 0,8-1,2; магний 0,005-0.01; алюминий 0,1-0,3; никель 3,0-3,6; ванадий 1,5-2,0; бор 0,1-0,2; кобальт 0,2-0,3; селен 0,001-0,01; железо - остальное. В таблице приведены составы чугуна.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, aluminum, nickel, vanadium, boron, cobalt, iron, additionally contains selenium in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 1.8-2.2; manganese 0.8-1.2; magnesium 0.005-0.01; aluminum 0.1-0.3; nickel 3.0-3.6; vanadium 1.5-2.0; boron 0.1-0.2; cobalt 0.2-0.3; selenium 0.001-0.01; iron is the rest. The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Никель и кобальт улучшают металлическую основу сплава, препятствуют отбеливанию. Ванадий повышает вязкость и пластичность сплава. Бор стабилизирует карбиды. Селен в структуре сплава имеет виц мелкораздробленных неметаллических включений, находящихся между частицами металла. Действие марганца, тормозящего выделение графита, способствует получению мелкозернистой структуры чугуна. Алюминий и магний раскисляют чугун, препятствуют росту зерна.In the composition of cast iron, the components manifest themselves as follows. Nickel and cobalt improve the metal base of the alloy, prevent bleaching. Vanadium increases the viscosity and ductility of the alloy. Boron stabilizes carbides. Selenium in the alloy structure has vices of finely divided nonmetallic inclusions located between metal particles. The effect of manganese, inhibiting the release of graphite, contributes to the production of a fine-grained structure of cast iron. Aluminum and magnesium deoxidize cast iron and inhibit grain growth.
Чугун выплавляют в электропечах и отливают в формы. 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 molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
