Abstract
Description
Изобретение относится к области металлургии, а именно к составам ковкого чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, and in particular to malleable cast iron compositions that can be used in mechanical engineering.
Известен ковкий чугун, мас.%: углерод 2,5-2,9; кремний 0,8-1,2; марганец 0,3-0,6; церий 0,3-0,15; самарий 0,1-0,15; алюминий 0,02-0,03; железо - остальное [1].Known malleable cast iron, wt.%: Carbon 2.5-2.9; silicon 0.8-1.2; manganese 0.3-0.6; cerium 0.3-0.15; samarium 0.1-0.15; aluminum 0.02-0.03; iron - the rest [1].
Задачей изобретения является повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что ковкий чугун, содержащий углерод, кремний, церий, самарий, железо, дополнительно содержит никель и кобальт при следующем соотношении компонентов, мас.%: углерод 2,5-2,9; 0,8-1,2; марганец 0,4-0,6; церий 0,1-0,15; самарий 0,4-0,5; никель 0,6-0,9; кобальт 0,6-0,9; железо - остальное.The technical result is achieved by the fact that malleable cast iron containing carbon, silicon, cerium, samarium, iron, additionally contains nickel and cobalt in the following ratio of components, wt.%: Carbon 2.5-2.9; 0.8-1.2; manganese 0.4-0.6; cerium 0.1-0.15; samarium 0.4-0.5; nickel 0.6-0.9; cobalt 0.6-0.9; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе ковкого чугуна компоненты проявляют себя следующим образом. Кобальт и никель повышают прочность и твердость сплава. Алюминий повышает вязкость чугуна, препятствует возникновению и развитию трещин. Церий и самарий раскисляют сплав. Церий нейтрализует вредное влияние примесей серы.In the composition of ductile iron, the components manifest themselves as follows. Cobalt and nickel increase the strength and hardness of the alloy. Aluminum increases the viscosity of cast iron, prevents the occurrence and development of cracks. Cerium and samarium deoxidize the alloy. Cerium neutralizes the harmful effects of sulfur impurities.
Чугун выплавляют в электропечах и отливают в горячие (400-500°C) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 930-950°C и отпуску при температуре 700-720°.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. The castings are subjected to normalization at a temperature of 930-950 ° C and tempering at a temperature of 700-720 °.
