Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов, печей.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used for the manufacture of parts of thermal units, furnaces.
Известен чугун, включающий, мас.%: углерод 3,6-3,8; кремний 0,3-0,5; марганец 0,4-0,5; алюминий 2,0-3,0; бор 0,03-0,06; магний 0,03-0,08; железо - остальное [1].Known cast iron, including, wt.%: Carbon 3.6-3.8; silicon 0.3-0.5; manganese 0.4-0.5; aluminum 2.0-3.0; boron 0.03-0.06; magnesium 0.03-0.08; iron - the rest [1].
Задачей изобретения является повышение 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, алюминий, бор, магний, железо, дополнительно включает вольфрам и эрбий при следующем соотношении компонентов, мас.%: углерод 3,6-3,8; кремний 0,3-0,5; марганец 0,2-0,3; алюминий 0,8-1,2; бор 0,08-0,1; магний 0,001-0,002; вольфрам 0,8-1,2; эрбий 0,15-0,25; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, boron, magnesium, iron, additionally includes tungsten and erbium in the following ratio of components, wt.%: Carbon 3,6-3,8; silicon 0.3-0.5; manganese 0.2-0.3; aluminum 0.8-1.2; boron 0.08-0.1; magnesium 0.001-0.002; tungsten 0.8-1.2; erbium 0.15-0.25; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В чугуне компоненты проявляют себя следующим образом. Магний раскисляет сплав, эрбий препятствует возникновению и развитию трещин при перепадах температур. Бор стабилизирует карбиды, увеличивает прокаливаемость изделий. Алюминий препятствует росту окалины, повышает вязкость сплава. Вольфрам увеличивает твердость и работоспособность чугунных изделий при высоких температурах.In cast iron, the components manifest themselves as follows. Magnesium deoxidizes the alloy, erbium prevents the occurrence and development of cracks at temperature extremes. Boron stabilizes carbides, increases the hardenability of products. Aluminum inhibits the growth of scale, increases the viscosity of the alloy. Tungsten increases the hardness and performance of cast iron products at high temperatures.
Чугун выплавляют в электропечах и отливают в обмазанные огнеупорной глиной кокили, предварительно нагретые до температуры 400°С. Отливки подвергают отжигу при температуре 730°C с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into chill molds coated with refractory clay, preheated to a temperature of 400 ° C. The castings are annealed at a temperature of 730 ° C, followed by cooling in air.
