Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов, печей.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, furnaces.
Известен чугун следующего состава, мас.%: углерод 3,0-3,8; кремний 3,0-3,5; марганец 0,1-0,6; молибден 0,1-0,2; магний 0,03-0,08; медь 0,2-0,6; церий 0,05-0,1; железо - остальное [1]. Термостойкость такого чугуна не превышает 220 циклов.Known cast iron of the following composition, wt.%: Carbon 3.0-3.8; silicon 3.0-3.5; manganese 0.1-0.6; molybdenum 0.1-0.2; magnesium 0.03-0.08; copper 0.2-0.6; cerium 0.05-0.1; iron - the rest [1]. The heat resistance of such cast iron does not exceed 220 cycles.
Задача изобретения состоит в повышении 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, молибден, медь, церий, дополнительно содержит гафний, рений и титан, при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 3,0-3,6; марганец 0,4-0,6; молибден 0,1-0,2; медь 0,8-1,0; церий 0,2-0,25; гафний 0,5-0,9; рений 0,1-0,15; титан 0,05-0,1; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, copper, cerium, additionally contains hafnium, rhenium and titanium, with the following ratio of components, wt.%: Carbon 3.0-3.6; silicon 3.0-3.6; manganese 0.4-0.6; molybdenum 0.1-0.2; copper 0.8-1.0; cerium 0.2-0.25; hafnium 0.5-0.9; rhenium 0.1-0.15; titanium 0.05-0.1; 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. Молибден повышает прочностные характеристики чугуна, увеличивает твердость, делает его теплоустойчивым. Гафний и рений увеличивают твердость и работоспособность сплава при высоких температурах. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Церий выполняет функцию раскислителя, нейтрализует влияние примесей серы. Титан обеспечивает мелкозернистостъ структуры сплава.In the composition of cast iron, the components manifest themselves as follows. Molybdenum increases the strength characteristics of cast iron, increases hardness, makes it heat-resistant. Hafnium and rhenium increase the hardness and performance of the alloy at high temperatures. Copper promotes graphitization, increases the content of perlite in the alloy. Cerium acts as a deoxidizing agent and neutralizes the influence of sulfur impurities. Titanium provides a fine-grained alloy structure.
Чугун выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
