Abstract
Description
Изобретение относится к области металлургии, в частности к составам ковкого чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular to malleable iron compositions, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 2,0-2,9; кремний 1,0-1,7; марганец 0,1-0,5; магний 0,01-0,05; медь 0,4-0,7; иттрий 0,01-0,04; празеодим 0,02-0,05; ниобий 0,05-0,25; алюминий 0,05-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.0-2.9; silicon 1.0-1.7; manganese 0.1-0.5; magnesium 0.01-0.05; copper 0.4-0.7; yttrium 0.01-0.04; praseodymium 0.02-0.05; niobium 0.05-0.25; aluminum 0.05-0.2; iron - the rest [1].
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; РЗМ 0-0,2; ниобий 0-1,0; алюминий 0-0,2; цирконий 0-1,0; титан 0-1,0; хром 0-1,5; железо - остальное [2].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; copper 0-4.0; REM 0-0.2; niobium 0-1.0; aluminum 0-0.2; zirconium 0-1.0; titanium 0-1.0; chrome 0-1.5; iron - the rest [2].
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, медь, РЗМ, ниобий, алюминий, цирконий, титан, хром, железо, дополнительно содержит магний, при следующем соотношении компонентов, мас.%: углерод 2,5-3,0; кремний 1,0-1,5; марганец 0,3-0,5; медь 0,4-0,8; РЗМ 0,05-0,15; ниобий 0,3-0,5; алюминий 0,05-0,1; цирконий 0,5-1,0; титан 0,2-0,4; хром 0,2-0,4; магний 0,005-0,01; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, rare-earth metals, niobium, aluminum, zirconium, titanium, chromium, iron, additionally contains magnesium, in the following ratio of components, wt.%: Carbon 2.5-3 0; silicon 1.0-1.5; manganese 0.3-0.5; copper 0.4-0.8; REM 0.05-0.15; niobium 0.3-0.5; aluminum 0.05-0.1; zirconium 0.5-1.0; titanium 0.2-0.4; chrome 0.2-0.4; magnesium 0.005-0.01; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Предел прочности чугуна при растяжении составит ~800 МПа для всех приведенных в таблице составов.The tensile strength of cast iron will be ~ 800 MPa for all the compositions listed in the table.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Медь способствует графитизации, увеличивает содержанию в сплаве перлита. Марганец способствует измельчению перлита. Кальций, РЗМ и алюминий выполняют функцию раскислителей. Ниобий и цирконий улучшают металлическую основу чугуна. Титан придает структуре чугуна мелкозернистость.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Copper promotes graphitization, increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Calcium, rare-earth metals and aluminum act as deoxidizers. Niobium and zirconium improve the metal base of cast iron. Titanium gives the structure of cast iron 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.
