Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам ковкого чугуна, который может быть использован в машиностроении.The invention relates to the field of ferrous metallurgy, and in particular to malleable iron compositions, which can be used in mechanical engineering.
Известен ковкий чугун, содержащий, мас.%: углерод 2,5-3,1; кремний 0,9-1,3; марганец 0,9-1,3; церий 0,07-0,15; самарий 0,07-0,15; алюминий 0,015-0,03; бор 0,03-0,07; азот 0,07-0,15; железо - остальное [1].Known malleable cast iron, containing, wt.%: Carbon 2.5-3.1; silicon 0.9-1.3; manganese 0.9-1.3; cerium 0.07-0.15; samarium 0.07-0.15; aluminum 0.015-0.03; boron 0.03-0.07; nitrogen 0.07-0.15; 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, марганец, церий, самарий, алюминий, бор, азот, железо, дополнительно содержит серебро при следующем соотношении компонентов, мас.%: углерод 2,5-2,9; кремний 0,8-1,2; марганец 0,4-0,6; церий 0,03-0,08; самарий 0,03-0,08; алюминий 0,1-0,15; бор 0,03-0,08; азот 0,03-0,08; серебро 0,003-0,008; железо - остальное.The technical result is achieved by the fact that malleable cast iron containing carbon, silicon, manganese, cerium, samarium, aluminum, boron, nitrogen, iron, additionally contains silver in the following ratio of components, wt.%: Carbon 2.5-2.9; silicon 0.8-1.2; manganese 0.4-0.6; cerium 0.03-0.08; samarium 0.03-0.08; aluminum 0.1-0.15; boron 0.03-0.08; nitrogen 0.03-0.08; silver 0.003-0.008; 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. Церий и самарий раскисляют сплав. Церий нейтрализует вредное влияние примесей серы. Бор стабилизирует карбиды, увеличивает твердость и прочность чугуна. Азот в химически связанном состоянии с алюминием образует нитриды, становится легирующим элементом, улучшающим структуру и механические свойства сплава. Серебро способствует измельчению зерна.In the composition of ductile iron, the components manifest themselves as follows. Cerium and samarium deoxidize the alloy. Cerium neutralizes the harmful effects of sulfur impurities. Boron stabilizes carbides, increases the hardness and strength of cast iron. Nitrogen in a chemically bound state with aluminum forms nitrides, becomes an alloying element that improves the structure and mechanical properties of the alloy. Silver helps to chop grain.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 930-950°С 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. Castings are subjected to normalization at a temperature of 930-950 ° C and tempering at a temperature of 700-720 °.
