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 3,0-4,5; кремний 0,5-1,8; марганец 0,1-0,6; магний 0,03-0,1; алюминий 0,5-0,9; железо - остальное [1].Known cast iron, including, wt.%: Carbon 3.0-4.5; silicon 0.5-1.8; manganese 0.1-0.6; magnesium 0.03-0.1; aluminum 0.5-0.9; 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, кремнии, марганец, алюминий, железо, дополнительно включает бор, вольфрам, кобальт и медь, при следующем соотношении компонентов, мас.%: углерод 3,0-3,4; кремний 0,5-1,0; марганец 0,4-0,8; алюминий 1,5-2,0; бор 0,03-0,05; вольфрам 0,2-0,26; кобальт 0,3-0,5; медь 0,3-0,5; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, iron, additionally includes boron, tungsten, cobalt and copper, with the following ratio of components, wt.%: Carbon 3.0-3.4; silicon 0.5-1.0; manganese 0.4-0.8; aluminum 1.5-2.0; boron 0.03-0.05; tungsten 0.2-0.26; cobalt 0.3-0.5; copper 0.3-0.5; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В чугуне компоненты проявляют себя следующим образом. Вольфрам, кобальт, медь увеличивают прочностные свойства чугуна, препятствуют возникновению и развитию трещин при перепадах температур. Алюминий препятствует росту окалины, раскисляет чугун, увеличивает его вязкость. Бор способствует равномерному нагреву и остыванию изделий из чугуна.In cast iron, the components manifest themselves as follows. Tungsten, cobalt, copper increase the strength properties of cast iron, prevent the occurrence and development of cracks at temperature extremes. Aluminum inhibits the growth of scale, deoxidizes cast iron, and increases its viscosity. Boron promotes uniform heating and cooling of cast iron products.
Чугун выплавляют в электропечах и отливают центробежным способом в обмазанные огнеупорной глиной кокили, предварительно нагретые до температуры 350-450°С. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast in a centrifugal way into chills coated with refractory clay, preheated to a temperature of 350-450 ° C. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
