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 0,01-0,07; 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 0.01-0.07; 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. Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, титан, РЗМ, алюминий, кальций, магний, медь, железо, дополнительно содержит кобальт при следующем соотношении компонентов, мас.%: углерод 3,2-3,6; кремний 1,0-1,4; марганец 0,3-0,7; хром 0,1-0,15; титан 0,13-0,17; РЗМ 0,13-0,17; алюминий 0,4-0,6; кальций 0,002-0,004; магний 0,002-0,004; медь 2,9-3,1; кобальт 2,9-3,1; железо - остальное.The objective of the invention is to increase the strength of cast iron. 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 cobalt in the following ratio of components, wt.%: Carbon 3,2-3, 6; silicon 1.0-1.4; manganese 0.3-0.7; chrome 0.1-0.15; titanium 0.13-0.17; REM 0.13-0.17; aluminum 0.4-0.6; calcium 0.002-0.004; magnesium 0.002-0.004; copper 2.9-3.1; cobalt 2.9-3.1; 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. Медь улучшает металлическую основу сплава, повышает его прочность и пластичность, снижает склонность к образованию трещин. Кобальт и алюминии повышают прочность и вязкость сплава. Карбиды стабилизируются хромом. Кальций, магний и РЗМ раскисляют сплав. Титан способствует получению мелкозернистой структуры чугуна.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. Cobalt and aluminum increase the strength and toughness of the alloy. Carbides are stabilized by chromium. Calcium, magnesium and rare-earth metals deoxidize the alloy. Titanium contributes to the production of a fine-grained structure of cast iron.
Чугун выплавляют в вагранках, дуплекс-процессом или 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 cupolas, a duplex process or 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.
