Abstract
Description
Изобретение откосятся к области черной металлургии, в частности к составам чугуна, который может быть использован, например, в энергетическом машиностроении.The invention relates to the field of ferrous metallurgy, in particular to the composition of cast iron, which can be used, for example, in power engineering.
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; магния 0,03-0,08; медь 0,2-0,6; церий 0,05-0,1; железо - остальное [1]. Термостойкость этого чугуна составляет 203-220 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 this cast iron is 203-220 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, магний, медь, церий, железо, дополнительно содержит титан и гафний при следующем соотношении компонентов, мас.%: углерод 3,0-3,8; кремний 3,0-3,5; марганец 0,6-1,2; молибден 0,2-0,6; магний 0,03-0,08; медь 0,2-0,6; церий 0,1-0,2; титан 0,4-0,8; гафний 1,0-1,8; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, magnesium, copper, cerium, iron, additionally contains titanium and hafnium in the following ratio of components, wt.%: Carbon 3.0-3.8; silicon 3.0-3.5; manganese 0.6-1.2; molybdenum 0.2-0.6; magnesium 0.03-0.08; copper 0.2-0.6; cerium 0.1-0.2; titanium 0.4-0.8; hafnium 1.0-1.8; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Термостойкость чугуна для всех составов, приведенных в таблице, составит ~350 циклов (нагрев до 850°С и охлаждение) до появления трещин.The heat resistance of cast iron for all compositions listed in the table will be ~ 350 cycles (heating to 850 ° C and cooling) until cracks appear.
В составе чугуна компоненты проявляют себя следующим образом. Молибден и гафний упрочняют твердый раствор. Марганец стабилизирует карбиды. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Магний и церий выполняют функцию раскислителей. Титан обеспечивает мелкозернистость структуре чугуна.In the composition of cast iron, the components manifest themselves as follows. Molybdenum and hafnium strengthen the solid solution. Manganese stabilizes carbides. Copper promotes graphitization, increases the content of perlite in the alloy. Magnesium and cerium act as deoxidizers. Titanium provides a fine grain structure of cast iron.
Чугун выплавляют в электропечах и отливают формы. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. In order to prevent bleaching caused by the addition of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
