Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован в автомобилестроении, производстве тракторов.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in the automotive industry, the production of tractors.
Известен чугун, содержащий, мас.%: углерод 3,1-3,8; кремний 1,4-2,5; марганец 0,3-0,8; хром 0,4-0,8; никель 0,06-0,5; медь 0,5-1,5; титан 0,03-0,08; ванадий 0,05-0,3; церий 0,005-0,5; бор 0,003-0,009; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.1-3.8; silicon 1.4-2.5; manganese 0.3-0.8; chrome 0.4-0.8; nickel 0.06-0.5; copper 0.5-1.5; titanium 0.03-0.08; vanadium 0.05-0.3; cerium 0.005-0.5; boron 0.003-0.009; iron - the rest [1].
Задача изобретения - повышение усталостной прочности чугуна.The objective of the invention is to increase the fatigue strength of cast iron.
Технический результат достигается тем, что в чугуне, содержащем углерод, кремний, марганец, хром, никель, медь, титан, ванадий, церий, бор, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,8-3,2; кремний 1,2-1,3; марганец 0,2-0,4; хром 0,2-0,4; никель 3,8-4,2; медь 1,8-2,2, титан 0,03-0,08; ванадий 0,4-0,6; церий 0,55-0,65; бор 0,02-0,04; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, chromium, nickel, copper, titanium, vanadium, cerium, boron, iron, the components are in the following ratio, wt.%: Carbon 2.8-3.2 ; silicon 1.2-1.3; manganese 0.2-0.4; chrome 0.2-0.4; nickel 3.8-4.2; copper 1.8-2.2, titanium 0.03-0.08; vanadium 0.4-0.6; cerium 0.55-0.65; boron 0.02-0.04; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Ванадий упрочняет твердый раствор. Никель улучшает структуру чугуна. Хром и бор стабилизируют карбиды. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Церий выполняет функцию раскислителя. Титан придает мелкозернистость структуре чугуна.The components present in the composition of cast iron manifest themselves as follows. Vanadium strengthens the solid solution. Nickel improves the structure of cast iron. Chrome and boron stabilize carbides. Copper promotes graphitization, increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Cerium acts as a deoxidizing agent. Titanium gives a fine grain structure to 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.
