Abstract
Description
Изобретение относится к области металлургии, а именно к составам чугуна, который может быть использован для изготовления деталей печей.The invention relates to the field of metallurgy, and in particular to compositions of cast iron, which can be used for the manufacture of furnace parts.
Известен чугун, содержащий, мас.%: углерод 2,5-3,5; кремний 1,5-2,5; марганец 1,0-5,0; хром 1,0-4,0; алюминий 0,3-3,0; титан 0,05-1,0; бор 0,005-0,03; никель 0,02-0,04; магний 0,01-0,1; кальций 0,02-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-3.5; silicon 1.5-2.5; manganese 1.0-5.0; chrome 1.0-4.0; aluminum 0.3-3.0; titanium 0.05-1.0; boron 0.005-0.03; nickel 0.02-0.04; magnesium 0.01-0.1; calcium 0.02-0.2; iron - the rest [1].
Задачей изобретения является повышение жаростойкости 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, хром, алюминий, титан, бор, никель, магний, кальций, железо, компоненты находятся при следующем соотношении компонентов, мас.%: углерод 2,5-3,5; кремний 1,5-2,0; марганец 0,5-0,9; хром 3,2-3,5; алюминий 4,4-4,8; титан 0,05-0,1; бор 0,52-0,6; никель 2,1-2,9; магний 0,001-0,003; кальций 0,002-0,003; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, chromium, aluminum, titanium, boron, nickel, magnesium, calcium, iron, the components are in the following ratio of components, wt.%: Carbon 2.5-3, 5; silicon 1.5-2.0; manganese 0.5-0.9; chrome 3.2-3.5; aluminum 4.4-4.8; titanium 0.05-0.1; boron 0.52-0.6; nickel 2.1-2.9; magnesium 0.001-0.003; calcium 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. Никель и марганец препятствуют появлению и развитию трещин при перепадах температур. Бор стабилизирует карбиды, повышает твердость и прокаливаемостъ сплава. Алюминий и хром препятствуют росту окалины. Магний и кальций выполняют функцию раскислителей. Титан способствует измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. Nickel and manganese prevent the appearance and development of cracks at temperature extremes. Boron stabilizes carbides, increases the hardness and hardenability of the alloy. Aluminum and chromium inhibit the growth of scale. Magnesium and calcium act as deoxidizers. Titanium helps to chop grain.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
