Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун следующего состава, мас.%: углерод 3,3-3,8; кремний 2,4-4,0; марганец 0,45-1,0; хром 0,05-0,4; медь 0,7-1,2; магний 0,01-0,04; РЗМ 0,002-0,06; кальций 0,006-0,05; железо остальное [1].Known cast iron of the following composition, wt.%: Carbon 3.3-3.8; silicon 2.4-4.0; manganese 0.45-1.0; chrome 0.05-0.4; copper 0.7-1.2; magnesium 0.01-0.04; REM 0.002-0.06; calcium 0.006-0.05; 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, включающий углерод, кремний, марганец, хром, медь, магний, железо, отличается тем, что дополнительно содержит вольфрам и ванадий при следующем соотношении компонентов, мас.%: углерод 3,3-3,8; кремний 2,4-4,0; марганец 0,4-0,8; хром 0,1-0,2; медь 1,6-2,2; магний 0,002-0,004; вольфрам 0,5-1,0; ванадий 0,4-0,6; железо остальное.The technical result is achieved in that cast iron, including carbon, silicon, manganese, chromium, copper, magnesium, iron, is characterized in that it additionally contains tungsten and vanadium in the following ratio of components, wt.%: Carbon 3.3-3.8; silicon 2.4-4.0; manganese 0.4-0.8; chrome 0.1-0.2; copper 1.6-2.2; magnesium 0.002-0.004; tungsten 0.5-1.0; vanadium 0.4-0.6; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Хром, медь, вольфрам, ванадий увеличивают прочности и твердость чугуна. Вольфрам и ванадий препятствуют возникновению трещин в изделиях при механических нагрузках. Магний раскисляет сплав.In the composition of cast iron, the components manifest themselves as follows. Chrome, copper, tungsten, vanadium increase the strength and hardness of cast iron. Tungsten and vanadium prevent cracking in products under mechanical stress. Magnesium deoxidizes the alloy.
Чугун выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°C.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
