Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может бить использовал в подъемно-транспортном, железнодорожном, строительно-дорожном машиностроении, автомобильной промышленности.The invention relates to the field of ferrous metallurgy, in particular to the compositions of cast iron, which can beat used in hoisting-and-transport, railway, construction and road engineering, automotive industry.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; хром 0,01-2,0; никель 0,01-5,0; алюминий 0,01-0,1; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; chromium 0.01-2.0; nickel 0.01-5.0; aluminum 0.01-0.1; 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 чугун, содержащий углерод, кремний, марганец, хром, никель, алюминий, железо, дополнительно содержит церий при следующем соотношении компонентов, мас.%: углерод 2,2-2,6; кремний 1,2-1,6; марганец 1,0-1,5; хром 0,5-1,5; никель 3,5-4,5; алюминий 0.05-0,15; церий 0,1-0,2, железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, nickel, aluminum, iron, additionally contains cerium in the following ratio of components, wt.%: Carbon 2.2-2.6; silicon 1.2-1.6; manganese 1.0-1.5; chrome 0.5-1.5; nickel 3.5-4.5; aluminum 0.05-0.15; cerium 0.1-0.2, iron - the rest.
В таблице приведены примеры составов чугунаThe table shows examples of cast iron compositions
Предел прочности чугуна при изгибе ~90 кгс/мм2 для всех приведенных в таблице составов.The bending strength of cast iron is ~ 90 kgf / mm 2 for all the compositions listed in the table.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов. В составе чугуна выделения графита имеют пластинчатую форму. Марганец и хром стабилизируют карбиды. Никель препятствует отбеливанию чугуна, улучшает его металлическую основу. Церий нейтрализует вредное влияние на прочностные характеристики чугуна примесей серы и выполняет наряду с алюминием функцию раскислителя, способствует получению мелкозернистой структуры сплава.The increase in the strength of cast iron is due to the complex effect of the components. In the composition of cast iron, graphite precipitates have a lamellar shape. Manganese and chromium stabilize carbides. Nickel prevents bleaching of cast iron, improves its metal base. Cerium neutralizes the harmful effect of sulfur impurities on the strength characteristics of cast iron and, along with aluminum, acts as a deoxidizing agent and contributes to the production of a fine-grained alloy structure.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-150°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-150 ° C.
