Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of parts of thermal units.
Известен чугун следующего состава, мас.%: углерод 3,2-4,5; кремний 0,6-1,8; марганец 1,7-2,6; азот 0,003-0,006; титан 0,002-0,005; церий 0,01-0,03; лантан 0,006-0,02; неодим 0,005-0,02; празеодим 0,005-0,02; алюминий 0,3-4,0; железо остальное [1].Known cast iron of the following composition, wt.%: Carbon 3.2-4.5; silicon 0.6-1.8; manganese 1.7-2.6; nitrogen 0.003-0.006; titanium 0.002-0.005; cerium 0.01-0.03; lanthanum 0.006-0.02; neodymium 0.005-0.02; praseodymium 0.005-0.02; aluminum 0.3-4.0; iron the rest [1].
Задачей изобретения является повышение термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что в чугуне, содержащем углерод, кремний, марганец, церий, празеодим, алюминий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 3,2-4,5; кремний 1,2-1,8; марганец 1,7-2,6; церий 2,2-2,4; празеодим 2,2-2,4; алюминий 4,5-6,5; железо остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, cerium, praseodymium, aluminum, iron, the components are in the following ratio, wt.%: Carbon 3.2-4.5; silicon 1.2-1.8; manganese 1.7-2.6; cerium 2.2-2.4; praseodymium 2.2-2.4; aluminum 4.5-6.5; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Празеодим, церий, алюминий повышают термостойкость сплава. Алюминий обеспечивает равномерный прогрев и охлаждение чугунных изделий, препятствует образованию трещин при резких перепадах температур.In the composition of cast iron, the components manifest themselves as follows. Praseodymium, cerium, aluminum increase the heat resistance of the alloy. Aluminum provides uniform heating and cooling of cast iron products, prevents the formation of cracks during sudden changes in temperature.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 600°С.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 600 ° C.
