Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления изделий, работающих в условиях термоциклирования.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of products operating in thermal cycling.
Известен чугун, содержащий, мас.%: углерод 1,0-4,0; кремний 0,1-2,5; марганец 0,1-15,0; магний 0-1,0; вольфрам 0-5,0; молибден 0-2,0; ниобий 0-2,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.0-4.0; silicon 0.1-2.5; manganese 0.1-15.0; magnesium 0-1.0; tungsten 0-5.0; molybdenum 0-2.0; niobium 0-2.0; 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 чугун, содержащий углерод, кремний, марганец, магний, вольфрам, молибден, ниобий, железо, дополнительно содержит рений при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 1,1-1,5; марганец 0,4-0,8; магний 0001-0002; вольфрам 2,0-3,0; молибден 2,2-2,8; ниобий 2,2-2,8; рений 1.2-1,8; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, tungsten, molybdenum, niobium, iron, additionally contains rhenium in the following ratio of components, wt.%: Carbon 3.0-3.5; silicon 1.1-1.5; manganese 0.4-0.8; magnesium 0001-0002; tungsten 2.0-3.0; molybdenum 2.2-2.8; niobium 2.2-2.8; rhenium 1.2-1.8; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron

Повышение термостойкости чугуна достигается за счет комплексного влияния компонентов, присутствующих в его составе. Ниобий и молибден упрочняют твердый раствор. Вольфрам и рений обеспечивают чугуну твердость при повышенных температурах, улучшают его металлическую основу. Магний выполняет функцию раскислителя, способствует измельчению зерна.The increase in heat resistance of cast iron is achieved due to the complex effect of the components present in its composition. Niobium and molybdenum strengthen the solid solution. Tungsten and rhenium provide cast iron hardness at elevated temperatures, improve its metal base. Magnesium acts as a deoxidizer, contributes to the grinding of grain.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and cast into molds. Castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
