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].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].
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, церий, железо, дополнительно содержит никель, кобальт, кальций, серебро, при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 3,0-3,6; марганец 0,4-0,6; молибден 0,15-0,25; магний 0,002-0,003; церий 0,13-0,15; никель 0,6-0,8; кобальт 0,2-0,3; кальций 0,002-0,003; серебро 0,002-0,003; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, magnesium, cerium, iron, additionally contains nickel, cobalt, calcium, silver, with the following ratio of components, wt.%: Carbon 3.0-3.6 ; silicon 3.0-3.6; manganese 0.4-0.6; molybdenum 0.15-0.25; magnesium 0.002-0.003; cerium 0.13-0.15; nickel 0.6-0.8; cobalt 0.2-0.3; calcium 0.002-0.003; silver 0.002-0.003; 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, кобальт, никель повышают прочностные характеристики сплава, увеличивают его твердость. Молибден делает сплав теплоустойчивым, увеличивает несущую способность деталей при ударных нагрузках и высоких температурах. Кобальт и никель увеличивают вязкость сплава. Церий и кальций выполняют функцию раскислителей, церий нейтрализует влияние примесей серы. Серебро незначительно препятствует возникновению трещин при перепадах температур.In the composition of cast iron, the components manifest themselves as follows. Molybdenum, cobalt, nickel increase the strength characteristics of the alloy, increase its hardness. Molybdenum makes the alloy heat-resistant, increases the load-bearing capacity of parts under shock loads and high temperatures. Cobalt and nickel increase the viscosity of the alloy. Cerium and calcium act as deoxidizing agents; cerium neutralizes the influence of sulfur impurities. Silver slightly prevents the occurrence of cracks at temperature extremes.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают отжигу при температуре 720-740°C 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.
