Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован в автомобилестроении.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used in the automotive industry.
Известен чугун, включающий, мас.%: углерод 3,2-3,8; кремний 2,6-3,0; марганец 0,2-0,7; магний 0,03-0,07; медь 0,71-1,1; церий 0,002-0,05; ниобий 0,005-0,21; молибден 0,8-1,1; алюминий 0,03-0,1; никель 0,4-1,2; железо - остальное [1].Known cast iron, including, wt.%: Carbon 3.2-3.8; silicon 2.6-3.0; manganese 0.2-0.7; magnesium 0.03-0.07; copper 0.71-1.1; cerium 0.002-0.05; niobium 0.005-0.21; molybdenum 0.8-1.1; aluminum 0.03-0.1; nickel 0.4-1.2; 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, церий, ниобий, молибден, алюминий, никель, железо, дополнительно включает гафний, олово и индий при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,8-2,2; марганец 0,8-1,2; медь 1,3-1,8; церий 0,08-0,12; ниобий 0,08-0,12; молибден 0,8-1,2; алюминий 0,08-0,12; никель 0,8-1,2; гафний 0,2-0,3; олово, 0,001-0,002; индий 0,001-0,002; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, cerium, niobium, molybdenum, aluminum, nickel, iron, additionally includes hafnium, tin and indium in the following ratio of components, wt.%: Carbon 2,8- 3.2; silicon 1.8-2.2; manganese 0.8-1.2; copper 1.3-1.8; cerium 0.08-0.12; niobium 0.08-0.12; molybdenum 0.8-1.2; aluminum 0.08-0.12; nickel 0.8-1.2; hafnium 0.2-0.3; tin, 0.001-0.002; indium 0.001-0.002; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Никель увеличивает прочностные и пластические свойства сплава. Молибден, ниобий и гафний повышают прочностные характеристики чугуна, его твердость. Медь способствует графитизации, препятствует образованию и развитию трещин. Церий и алюминий раскисляют сплав. Индий и олово способствуют измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. Nickel increases the strength and plastic properties of the alloy. Molybdenum, niobium and hafnium increase the strength characteristics of cast iron, its hardness. Copper promotes graphitization, prevents the formation and development of cracks. Cerium and aluminum deoxidize the alloy. Indium and tin contribute to the grinding of grain.
Чугун выплавляют в вагранках и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is melted in cupolas and cast into hot (400-450 ° С) metal molds coated with refractory clay. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
