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 01003-0,006; 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 01003-0.006; 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 чугун, содержащий углерод, кремний, марганец, лантан, неодим, празеодим, железо, дополнительно содержит кобальт или никель и серебро при следующем соотношении компонентов, мас. %: углерод 3,2-4,5; кремний 1,2-1,8; марганец 1,7-2,6; лантан 0,05-0,1; неодим 0,1-0,15; празеодим 0,1-0,15; кобальт или никель 3,3-4,1; серебро 0,005-0,01; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, lanthanum, neodymium, praseodymium, iron, additionally contains cobalt or nickel and silver in the following ratio of components, wt. %: carbon 3.2-4.5; silicon 1.2-1.8; manganese 1.7-2.6; lanthanum 0.05-0.1; neodymium 0.1-0.15; praseodymium 0.1-0.15; cobalt or nickel 3.3-4.1; silver 0.005-0.01; 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. Лантан, неодим, празеодим раскисляют сплав. Кобальт, никель повышают прочностные характеристики сплава, увеличивают сопротивление механическим нагрузкам при повышенных температурах. Серебро обеспечивает равномерный прогрев и охлаждение чугунных изделий.In the composition of cast iron, the components manifest themselves as follows. Lanthanum, neodymium, praseodymium deoxidize the alloy. Cobalt, nickel increase the strength characteristics of the alloy, increase resistance to mechanical stress at elevated temperatures. Silver provides uniform heating and cooling of cast iron products.
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.
