Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован для изготовления широкой номенклатуры деталей автомобилей, тракторов и сельхозмашин, текстильных машин, судов, вагонов.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used for the manufacture of a wide range of parts for cars, tractors and agricultural machines, textile machines, ships, wagons.
Известен чугун, содержащий, мас.%: углерод 0,5-3,0; кремний 3,0-7,0; марганец 0-10,0; хром 25,0-45,0; медь 0-7,0; титан 0-8,0; ванадий 0-8,0; цирконий 0-8,0; никель 0-13,0; азот 0-0,5; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 0.5-3.0; silicon 3.0-7.0; manganese 0-10.0; chrome 25.0-45.0; copper 0-7.0; titanium 0-8.0; vanadium 0-8.0; zirconium 0-8.0; nickel 0-13.0; nitrogen 0-0.5; 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, медь, алюминий, титан, ванадий, цирконий, никель, азот, железо, дополнительно включает магний, при следующем соотношении компонентов, мас.%: углерод 2,8-3,3; кремний 2,8-3,3; марганец 1,0-1,5; хром 0,5-1,0; медь 0,5-1,0; титан 0,05-0,1; ванадий 0,1-0,3; цирконий 0,1-0,2; никель 1,0-1,5; азот 0,05-0,1; алюминий 0,1-0,2; магний 0,01-0,02; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, copper, aluminum, titanium, vanadium, zirconium, nickel, nitrogen, iron, additionally includes magnesium, in the following ratio, wt.%: Carbon 2.8 -3.3; silicon 2.8-3.3; manganese 1.0-1.5; chrome 0.5-1.0; copper 0.5-1.0; titanium 0.05-0.1; vanadium 0.1-0.3; zirconium 0.1-0.2; nickel 1.0-1.5; nitrogen 0.05-0.1; aluminum 0.1-0.2; magnesium 0.01-0.02; 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. Никель упрочняет твердый раствор. Медь способствует увеличению содержания в сплаве перлита. Цирконий и титан, который образует карбонитриды, способствуют повышению механических свойств чугуна и придают мелкозернистость его структуре. Алюминий и магний раскиляют чугун.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. Nickel hardens the solid solution. Copper helps to increase the content of perlite in the alloy. Zirconium and titanium, which forms carbonitrides, contribute to the increase in the mechanical properties of cast iron and give a fine-grained structure. Aluminum and magnesium split the cast iron.
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.
