Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован, например, для изготовления конфорок газовых и электроплит.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used, for example, for the manufacture of gas burners and electric stoves.
Известен чугун, включающий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0-0,2; медь 0-4,0; никель 0-2,5; РЗМ 0-0,2; цирконий 0-1,0; ванадий 0-1,0; железо - остальное [1].Known cast iron, including, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; aluminum 0-0.2; copper 0-4.0; nickel 0-2.5; REM 0-0.2; zirconium 0-1.0; vanadium 0-1.0; iron - the rest [1].
Задача изобретения состоит в повышении термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, медь, никель, РЗМ, цирконий, ванадий, железо, дополнительно включает магний, при следующем соотношении компонентов, мас.%: углерод 2,7-3,3; кремний 0,7-2,5; марганец 0,5-1,0; алюминий 2,4-3,2; медь 0,2-0,45; никель 0,8-1,4; РЗМ 0,05-0,1; цирконий 0,1-0,2; ванадий 0,1-0,2; магний 0,005-0,01; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, nickel, rare-earth metals, zirconium, vanadium, iron, further includes magnesium, in the following ratio, wt.%: Carbon 2.7-3.3 ; silicon 0.7-2.5; manganese 0.5-1.0; aluminum 2.4-3.2; copper 0.2-0.45; nickel 0.8-1.4; REM 0.05-0.1; zirconium 0.1-0.2; vanadium 0.1-0.2; magnesium 0.005-0.01; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение термостойкости чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Медь увеличивает содержание в сплаве перлита. Марганец тормозит выделение графита и способствует размельчению перлита. При этом РЗМ, ванадий и магний выполняют функцию раскислителей. Никель упрочняет твердый раствор, предотвращает развитие трещин. Алюминий препятствует росту окалины.The increase in heat resistance of cast iron is due to the complex effect of the components that make up its composition. Copper increases the content of perlite in the alloy. Manganese inhibits the release of graphite and contributes to the crushing of perlite. In this case, rare-earth metals, vanadium and magnesium act as deoxidizers. Nickel strengthens the solid solution, prevents the development of cracks. Aluminum inhibits the growth of scale.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Температура расплава при заливке литейных форм должна быть не ниже 1320°С. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. The temperature of the melt when casting molds should be at least 1320 ° C. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
