Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован для изготовления кулачковых шайб, шестерен коленчатых и распределительных валов, цилиндров, рам, маховиков, поршней, зубчатых колес и других деталей.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used for the manufacture of cam washers, gears of crankshafts and camshafts, cylinders, frames, flywheels, pistons, gears and other details.
Известен чугун, содержащий, мас.%: углерод 1,0-3,0; кремний 0,3-2,0; марганец 0,1-2,0; алюминий 0,05-2,0; церий 0,001-0,2; хром 2,0-10,0; магний 0,001-0,2; цирконий 0,01-2,0; молибден 0,5-7,0; ванадий 2,0-15,0; железо остальное [1].Known cast iron, containing, wt.%: Carbon 1.0-3.0; silicon 0.3-2.0; manganese 0.1-2.0; aluminum 0.05-2.0; cerium 0.001-0.2; chrome 2.0-10.0; magnesium 0.001-0.2; zirconium 0.01-2.0; molybdenum 0.5-7.0; vanadium 2.0-15.0; 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 в составе чугуна, содержащем углерод, кремний, марганец, алюминий, церий, хром, магний, цирконий, молибден, ванадий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,0-2,5; кремний 2,0-2,5; марганец 0,5-1,0; алюминий 0,3-0,5; церий 0,05-0,1; хром 1,0-1,5; магний 0,05-0,1; цирконий 0,1-0,2; молибден 2,0-2,5; ванадий 0,5-1,0; железо - остальное.The technical result is achieved by the fact that in the composition of cast iron containing carbon, silicon, manganese, aluminum, cerium, chromium, magnesium, zirconium, molybdenum, vanadium, iron, the components are in the following ratio, wt.%: Carbon 2.0-2, 5; silicon 2.0-2.5; manganese 0.5-1.0; aluminum 0.3-0.5; cerium 0.05-0.1; chrome 1.0-1.5; magnesium 0.05-0.1; zirconium 0.1-0.2; molybdenum 2.0-2.5; vanadium 0.5-1.0; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Хром стабилизирует карбиды. Молибден и ванадий упрочняют твердый раствор. Алюминий, церий и магний раскисляют чугун. Цирконий придает мелкозернистость структуре сплава.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Chrome stabilizes carbides. Molybdenum and vanadium strengthen the solid solution. Aluminum, cerium and magnesium deoxidize cast iron. Zirconium gives a fine grain structure to the alloy.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. 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. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. 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.
