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, магний, медь, церий, дополнительно содержит свинец и натрий 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; магний 0,01-0,02; медь 1,0-1,3; церий 0,12-0,17; свинец 0,003-0,005; натрий 0,0001-0,0002; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, magnesium, copper, cerium, additionally contains lead and sodium 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; magnesium 0.01-0.02; copper 1.0-1.3; cerium 0.12-0.17; lead 0.003-0.005; sodium 0.0001-0.0002; 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 сплава, увеличивает твердость, делает его теплоустойчивым. Медь способствует равномерному прогреву чугунных изделий. Магний и церий выполняют функцию раскислителей. Свинец и натрий обеспечивают мелкозернистость структуры сплава, препятствуют образованию и развитию трещин при перепадах температур.In the composition of cast iron components manifest themselves as follows. Molybdenum increases the strength characteristics of the alloy, increases hardness, makes it heat-resistant. Copper promotes uniform heating of cast iron products. Magnesium and cerium act as deoxidizers. Lead and sodium provide a fine-grained structure of the alloy, prevent the formation and development of cracks at temperature extremes.
Чугун выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°C.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.
