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 1,5-4,0; кремний 1,5-6,0; марганец 0,05-2,5; магний 0-0,5; алюминий 0,1-2,0; ниобий 0,1-4,0; вольфрам 0,1-4,0; железо - остальное [1].Known cast iron, including, wt.%: Carbon 1.5-4.0; silicon 1.5-6.0; manganese 0.05-2.5; magnesium 0-0.5; aluminum 0.1-2.0; niobium 0.1-4.0; tungsten 0.1-4.0; 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 в чугуне, содержащем углерод, кремний, марганец, магний, алюминий, ниобий, вольфрам, железо, компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,4; кремний 0,5-1,0; марганец 0,4-0,8; магний 0,005-0,01; алюминий 0,7-1,1; ниобий 0,7-1,1; вольфрам 0,4-0,8; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, magnesium, aluminum, niobium, tungsten, iron, the components are in the following ratio, wt.%: Carbon 3.0-3.4; silicon 0.5-1.0; manganese 0.4-0.8; magnesium 0.005-0.01; aluminum 0.7-1.1; niobium 0.7-1.1; tungsten 0.4-0.8; 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 и ниобий упрочняют твердый раствор, увеличивают твердость и работоспособность сплава при высоких температурах. Алюминий препятствует росту окалины. Магний раскисляет чугун, обеспечивает мелкозернистость его структуры. Вольфрам упрочняет границы зерен.In cast iron, the components manifest themselves as follows. Tungsten and niobium strengthen the solid solution, increase the hardness and performance of the alloy at high temperatures. Aluminum inhibits the growth of scale. Magnesium deoxidizes cast iron, provides a fine-grained structure. Tungsten strengthens grain boundaries.
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°C 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.
