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 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 вольфрам при следующим соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 0,03-0,07; марганец 0,03-0,07; молибден 2,2-2,6; медь 0,4-0,5; тантал 0,17-0,23; бериллий 0,006-0,008; вольфрам 0,4-0,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, copper, tantalum, beryllium, iron, additionally contains tungsten in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 0.03-0.07; manganese 0.03-0.07; molybdenum 2.2-2.6; copper 0.4-0.5; tantalum 0.17-0.23; beryllium 0.006-0.008; tungsten 0.4-0.6; 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, вольфрам и тантал упрочняют твердый раствор, препятствуют возникновению и развитию трещин в чугуне при перепадах температур. Марганец стабилизирует карбиды. Медь способствует графитизации. Бериллий обеспечивает мелкозернистость структуры чугуна.In the composition of cast iron components manifest themselves as follows. Molybdenum, tungsten and tantalum strengthen the solid solution, prevent the occurrence and development of cracks in cast iron at temperature extremes. Manganese stabilizes carbides. Copper promotes graphitization. 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.
