Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого, преимущественно, для получения крупногабаритных отливок.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, used mainly for the production of large castings.
Известен чугун, содержащий, мас.%: углерод 2,5-2,9; кремний 1,4-1,8; марганец 0,4-0,6; алюминий 0,01-0,05; кальций 0,04-0,1; барий и/или стронций 0,08-0,2; хром 0,06-0,2; железо - остальное [1]. Предел прочности такого чугуна при растяжении 378-412 МПа.Known cast iron, containing, wt.%: Carbon 2.5-2.9; silicon 1.4-1.8; manganese 0.4-0.6; aluminum 0.01-0.05; calcium 0.04-0.1; barium and / or strontium 0.08-0.2; chrome 0.06-0.2; iron - the rest [1]. The tensile strength of such cast iron is 378-412 MPa.
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, алюминий, кальций, хром, железо, дополнительно содержит ванадий, бор, медь, при следующем соотношении компонентов, мас.%: углерод 2,2-3,0; кремний 1,2-1,8; марганец 0,8-1,2; алюминий 0,03-0,08; кальций 0,02-0,04; хром 0,6-1,0; ванадий 0,6-1,0; бор 0,03-0,08; медь 0,5-1,0; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, calcium, chromium, iron, additionally contains vanadium, boron, copper, in the following ratio of components, wt.%: Carbon 2.2-3.0; silicon 1.2-1.8; manganese 0.8-1.2; aluminum 0.03-0.08; calcium 0.02-0.04; chrome 0.6-1.0; vanadium 0.6-1.0; boron 0.03-0.08; copper 0.5-1.0; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Хром и бор стабилизируют карбиды. Ванадий упрочняет твердый раствор. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Кальций выполняет функцию раскислителя. Алюминий придает отливкам мелкозернистость.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Chrome and boron stabilize carbides. Vanadium strengthens the solid solution. Copper promotes graphitization, increases the content of perlite in the alloy. Calcium acts as a deoxidizer. Aluminum gives the castings a fine grain.
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 350-450°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 350-450 ° C.
