Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в энергетическом машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in power engineering.
Известен чугун следующего состава, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; молибден 0,01-2,0; медь 0-0,2; тантал 0,001-0,1; бериллий 0,01-0,2; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; molybdenum 0.01-2.0; copper 0-0.2; tantalum 0.001-0.1; beryllium 0.01-0.2; iron - the rest [1].
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, тантал, бериллий, железо, дополнительно содержит церий, при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 3,0-3,6; марганец 0,4-0,6; молибден 0,4-0,6; медь 0,8-1,2; тантал 0,8-1,2; бериллий 0,006-0,009; церий 0,06-0,1; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, copper, tantalum, beryllium, iron, additionally contains cerium, in the following ratio of components, wt.%: Carbon 3.0-3.6; silicon 3.0-3.6; manganese 0.4-0.6; molybdenum 0.4-0.6; copper 0.8-1.2; tantalum 0.8-1.2; beryllium 0.006-0.009; cerium 0.06-0.1; 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 и тантал упрочняют твердый раствор. Марганец стабилизирует карбиды. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Церий выполняет функцию раскислителя, нейтрализует влияние примесей серы. Бериллий обеспечивает мелкозернистость структуры чугуна.In the composition of cast iron, the components manifest themselves as follows. Molybdenum and tantalum strengthen the solid solution. Manganese stabilizes carbides. Copper promotes graphitization, increases the content of perlite in the alloy. Cerium acts as a deoxidizing agent and neutralizes the influence of sulfur impurities. Beryllium provides a fine-grained structure of cast iron.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into molds. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
