Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy and relates to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас. %: углерод 3,0-3,5; кремний 1,5-2,0; марганец 0,6-0,8; алюминий 0,15-0,25; азот 0,12-0,16; железо - остальное [1].Known cast iron, containing, by weight. %: carbon 3.0-3.5; silicon 1.5-2.0; manganese 0.6-0.8; aluminum 0.15-0.25; nitrogen 0.12-0.16; 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, алюминий, железо, дополнительно содержит кобальт, никель, медь, гафний, палладий при следующем соотношении компонентов, мас. %: углерод 3,0-3,5; кремний 1,0-1,3; марганец 0,6-0,8; алюминий 0,15-0,25; кобальт 4,0-4,4; никель 0,3-0,4; медь 0,9-1,3; гафний 0,5-0,6; палладий 0,006-0,008; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, iron, additionally contains cobalt, nickel, copper, hafnium, palladium in the following ratio of components, wt. %: carbon 3.0-3.5; silicon 1.0-1.3; manganese 0.6-0.8; aluminum 0.15-0.25; cobalt 4.0-4.4; nickel 0.3-0.4; copper 0.9-1.3; hafnium 0.5-0.6; palladium 0.006-0.008; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Кобальт, никель, гафний, медь, алюминий, палладий способствуют повышению прочности сплава. Никель, кобальт, алюминий, палладий препятствуют образованию и развитию трещин в чугунных отливках при механических нагрузках.Cobalt, nickel, hafnium, copper, aluminum, palladium increase the strength of the alloy. Nickel, cobalt, aluminum, palladium prevent the formation and development of cracks in iron castings under mechanical stress.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
