Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления вентилей, фитингов, корпусов, клапанов, шестерен, валов, цилиндров, маховиков, станин.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of valves, fittings, housings, valves, gears, shafts, cylinders, flywheels, frames.
Известен чугун, содержащий мас.%: углерод 3,18-4,1; кремний 1,96-3,12; марганец 0,23-0,71; хром 0,05-0,15; титан 0,01-0,1; РЗМ 0,001-0,07; алюминий 0,02-0,3; кальций 0,005-0,02; магний 0,01-0,05; медь 0,75-3,22; железо - остальное [1].Known cast iron containing wt.%: Carbon 3,18-4,1; silicon 1.96-3.12; manganese 0.23-0.71; chrome 0.05-0.15; titanium 0.01-0.1; REM 0.001-0.07; aluminum 0.02-0.3; calcium 0.005-0.02; magnesium 0.01-0.05; copper 0.75-3.22; iron - the rest [1].
Задача изобретения состоит в повышении прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, титан, РЗМ, алюминий, кальций, магний, медь, железо, дополнительно содержит цинк и бериллий при следующем соотношении компонентов, мас.%: углерод 3,1-3,5; кремний 0,9-1,5; марганец 1,2-1,6; хром 0,1-0,3; титан 0,1-0,16; РЗМ 0,1-0,2; алюминий 0,1-0,2; кальций 0,02-0,04; магний 0,002-0,008; медь 0,9-1,3; цинк 0,002-0,008; бериллий 0,06-0,12; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, titanium, rare-earth metals, aluminum, calcium, magnesium, copper, iron, additionally contains zinc and beryllium in the following ratio, wt.%: Carbon 3,1- 3.5; silicon 0.9-1.5; manganese 1.2-1.6; chrome 0.1-0.3; titanium 0.1-0.16; REM 0.1-0.2; aluminum 0.1-0.2; calcium 0.02-0.04; magnesium 0.002-0.008; copper 0.9-1.3; zinc 0.002-0.008; beryllium 0.06-0.12; iron is the rest.
В таблице приведены примеры составов чугуна.The table shows examples of cast iron compositions.
В составе чугуна компоненты проявляют себя следующим образом. Медь улучшает металлическую основу сплава, повышает его прочность и пластичность, снижает склонность к образованию трещин. Карбиды стабилизируются хромом. Алюминий, кальций, магний и РЗМ раскисляют сплав. Бериллий, титан и цинк способствуют получению мелкозернистой структуры.In the composition of cast iron, the components manifest themselves as follows. Copper improves the metal base of the alloy, increases its strength and ductility, reduces the tendency to crack. Carbides are stabilized by chromium. Aluminum, calcium, magnesium and rare-earth metals deoxidize the alloy. Beryllium, titanium and zinc contribute to obtaining a fine-grained structure.
Чугун выплавляют в электропечах и отливают в песчаные формы. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast in sand forms. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
