Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован для изготовления сцепных муфт, тормозных барабанов.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of couplers, brake drums.
Известен чугун, содержащий, мас.%: углерод 1,8-3,5; кремний 0,5-0,9, марганец 1,0-2,0; никель 4,5-6,0; хром 6,0-7,0; медь 0,2-0,5; церий 0,2-0,4; гафний 1,8-2,8; железо остальное [1].Known cast iron, containing, wt.%: Carbon 1.8-3.5; silicon 0.5-0.9, manganese 1.0-2.0; nickel 4.5-6.0; chrome 6.0-7.0; copper 0.2-0.5; cerium 0.2-0.4; hafnium 1.8-2.8; 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, никель, хром, медь, церий, гафний, железо, дополнительно включает олово при следующем соотношении компонентов, мас.%: углерод 3,0-3,2; кремний 1,8-2,2; марганец 0,6-0,8; никель 0,45-0,65; хром 0,4-0,6; медь 0,25-0,35; церий 0,11-0,13; гафний 1,8-2,2; олово 0,002-0,004; железо остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, nickel, chromium, copper, cerium, hafnium, iron, additionally includes tin in the following ratio of components, wt.%: Carbon 3.0-3.2; silicon 1.8-2.2; manganese 0.6-0.8; nickel 0.45-0.65; chrome 0.4-0.6; copper 0.25-0.35; cerium 0.11-0.13; hafnium 1.8-2.2; tin 0.002-0.004; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Хром стабилизирует карбиды. Никель повышает твердость и прочность сплава. Медь улучшает структуру чугуна, увеличивает пластичность. Гафний упрочняет твердый раствор, повышает прочность, твердость сплава. Церий выполняет функцию раскислителя. Олово придает мелкозернистость структуре чугуна.The components present in the composition of cast iron manifest themselves as follows. Chrome stabilizes carbides. Nickel increases the hardness and strength of the alloy. Copper improves the structure of cast iron, increases ductility. Hafnium strengthens the solid solution, increases the strength, hardness of the alloy. Cerium acts as a deoxidizing agent. Tin 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.
