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, железо, дополнительно включает медь, свинец и ванадий при следующем соотношении компонентов, мас.%: углерод 3,6-3,8; кремний 0,3-0,5; марганец 0,2-0,3; алюминий 2,0-3,0; бор 0,08-0,1; медь 1,0-1,4; свинец 0,01-0,015; ванадий 0,2-0,3; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, boron, iron, additionally includes copper, lead and vanadium in the following ratio of components, wt.%: Carbon 3,6-3,8; silicon 0.3-0.5; manganese 0.2-0.3; aluminum 2.0-3.0; boron 0.08-0.1; copper 1.0-1.4; lead 0.01-0.015; vanadium 0.2-0.3; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В чугуне компоненты проявляют себя следующим образом. Ванадий раскисляет и упрочняет сплав, препятствует возникновению и развитию трещин при перепадах температур. Бор стабилизирует карбиды, увеличивает прокаливаемость изделий. Алюминий препятствует росту окалины, повышает вязкость сплава. Медь повышает прочность и пластичность чугуна, способствует равномерному прогреву отливок. Свинец способствует измельчению зерна.In cast iron, the components manifest themselves as follows. Vanadium deoxidizes and strengthens the alloy, 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. Copper increases the strength and ductility of cast iron, promotes uniform heating of castings. Lead helps to chop grain.
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.
