Abstract
Description
Изобретение относится к составам чугуна, который может быть использован для изготовления деталей двигателей внутреннего сгорания.The invention relates to compositions of cast iron, which can be used for the manufacture of parts of internal combustion engines.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; РЗМ 0-0,2; цирконий 0-1,0; ванадий 0-1,0; 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; REM 0-0.2; zirconium 0-1.0; vanadium 0-1.0; boron 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 в чугуне, содержащем углерод, кремний, марганец, РЗМ, цирконий, ванадий, бор, железо, компоненты находятся в следующем соотношении, мас.%: углерод 3,2-3,8; кремний 1,0-2,0; марганец 0,2-0-6; РЗМ 0,3-0,5; цирконий 1,2-1,6; ванадий 0,3-0,5; бор 0,01-0,03; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, rare-earth metals, zirconium, vanadium, boron, iron, the components are in the following ratio, wt.%: Carbon 3.2-3.8; silicon 1.0-2.0; manganese 0.2-0-6; REM 0.3-0.5; zirconium 1.2-1.6; vanadium 0.3-0.5; boron 0.01-0.03; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Цирконий упрочняют твердый раствор. РЗМ и ванадий раскисляют сплав. Бор стабилизирует карбиды, способствует измельчению зерна, препятствуют образованию трещин.The components present in the composition of cast iron manifest themselves as follows. Zirconium hardened solid solution. REM and vanadium deoxidize the alloy. Boron stabilizes carbides, contributes to the grinding of grain, and prevents the formation of cracks.
Чугун выплавляют в электропечах и отливают формы. Температура расплава при заливке литейных форм должна быть ниже 1320°С. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. The temperature of the melt when casting molds should be below 1320 ° C. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
