Abstract
Description
Изобретение относится к области металлургии, в частности, к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular, to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, мас.%: углерод 3,0-3,4; кремний 1,6-2,2, марганец 0,005-0,04; ванадий 0,05-0,14; молибден 0,1-0,4; сурьма 0,05-0,1; гафний 0,14-0,27; железо - остальное [1].Known cast iron, wt.%: Carbon 3.0-3.4; silicon 1.6-2.2, manganese 0.005-0.04; vanadium 0.05-0.14; molybdenum 0.1-0.4; antimony 0.05-0.1; hafnium 0.14-0.27; 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, молибден, сурьму, гафний, железо, дополнительно включает кобальт, бор и РЗМ при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 1,3-1,9; марганец 0,5-1,0; молибден 0,2-0,3; сурьма 0,001-0,002; гафний 0,5-0,9; кобальт 1,7-2,3; бор 0,1-0,15; РЗМ 0,2-0,3; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, antimony, hafnium, iron, additionally includes cobalt, boron and rare-earth metals in the following ratio, wt.%: Carbon 3.0-3.5; silicon 1 , 3-1.9; manganese 0.5-1.0; molybdenum 0.2-0.3; antimony 0.001-0.002; hafnium 0.5-0.9; cobalt 1.7 to 2.3; boron 0.1-0.15; REM 0.2-0.3; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Марганец обеспечивает повышенную твердость чугуна. Молибден, гафний, кобальт способствуют увеличению прочности чугуна. РЗМ выполняют функцию раскислителя. Сурьма и бор способствуют образованию мелкозернистой структуры сплава, увеличивают твердость и прочность сплава. Бор стабилизирует карбиды.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Manganese provides increased hardness of cast iron. Molybdenum, hafnium, cobalt contribute to an increase in the strength of cast iron. REM perform the function of a deoxidizer . Antimony and boron contribute to the formation of a fine-grained structure of the alloy, increase the hardness and strength of the alloy. Boron stabilizes carbides.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлический формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°C 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.
