Abstract
Description
Изобретение относится к области металлургии, в частности, к составам серого чугуна, который может быть использован в общем машиностроении.The invention relates to the field of metallurgy, in particular, to compositions of gray cast iron, which can be used in general engineering.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0, кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0-0,2; хром 0-1,5; ванадий 0-1,0, молибден 0-0,8; стронций 0-0,2; бор 0-1,0, железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0, silicon 0.8-2.5; manganese 0.3-1.5; aluminum 0-0.2; chrome 0-1.5; vanadium 0-1.0, molybdenum 0-0.8; strontium 0-0.2; boron 0-1.0, iron - the rest [1].
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, алюминий, хром, ванадий, молибден, стронций, бор, железо, дополнительно включает магний и церий, при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,6-2,2; марганец 0,4-0,8; алюминий 0,4-0,8; хром 0,4-0,8; ванадий 0,4-0,8; молибден 1,8-2,2; стронций 0,04-0,08; бор 0,04-0,08; магний 0,02-0,04; церий 0,04-0,08, железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, chromium, vanadium, molybdenum, strontium, boron, iron, additionally includes magnesium and cerium, in the following ratio, wt.%: Carbon 2,8-3 , 2; silicon 1.6-2.2; manganese 0.4-0.8; aluminum 0.4-0.8; chrome 0.4-0.8; vanadium 0.4-0.8; molybdenum 1.8-2.2; strontium 0.04-0.08; boron 0.04-0.08; magnesium 0.02-0.04; cerium 0.04-0.08, iron - the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Хром стабилизирует карбиды. Молибден и ванадий упрочняют твердый раствор. Алюминий, церий и магний выполняют функцию раскислителей. Бор способствует измельчению зерна. Стронций уменьшает количество газовых включений в сплаве.The components present in the composition of cast iron manifest themselves as follows. Chrome stabilizes carbides. Molybdenum and vanadium strengthen the solid solution. Aluminum, cerium and magnesium act as deoxidizers. Boron contributes to grain refinement. Strontium reduces the amount of gas inclusions in 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. 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. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
