Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, который может быть использован в автомобилестроении и тракторостроении.The invention relates to the field of metallurgy and relates to compositions of cast iron, which can be used in the automotive and tractor industries.
Известен чугун, содержащий, мас. %: углерод 3,0-3,5; кремний 1,5-2,0; марганец 0,6-0,8; алюминий 0,15-0,25; азот 0,12-0,16; железо - остальное [1].Known cast iron, containing, by weight. %: carbon 3.0-3.5; silicon 1.5-2.0; manganese 0.6-0.8; aluminum 0.15-0.25; nitrogen 0.12-0.16; 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, алюминий, азот, железо, дополнительно содержит барий, никель и церий, при следующем соотношении компонентов, мас. %: углерод 3,0-3,5; кремний 1,5-2,0; алюминий 0,5-1,5; азот 0,0012-0,0016; барий 0,05-0,1; никель 1,5-3,0; церий 0,05-0,1; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, aluminum, nitrogen, iron, additionally contains barium, nickel and cerium, in the following ratio of components, wt. %: carbon 3.0-3.5; silicon 1.5-2.0; aluminum 0.5-1.5; nitrogen 0.0012-0.0016; barium 0.05-0.1; nickel 1.5-3.0; cerium 0.05-0.1; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Предел прочности на разрыв предложенного чугуна составит 60-65 МПа.The tensile strength of the proposed cast iron will be 60-65 MPa.
Повышение прочности чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Никель и азот способствуют повышению твердости и прочности сплава. Никель и алюминий повышают вязкость сплава, препятствуют образованию и развитию трещин в чугунных отливках при механических нагрузках. Барий выполняет функцию раскислителя.The increase in the strength of cast iron is achieved due to the complex effect of the components included in its composition. Nickel and nitrogen increase the hardness and strength of the alloy. Nickel and aluminum increase the viscosity of the alloy, prevent the formation and development of cracks in iron castings under mechanical stress. Barium acts as a deoxidizing agent.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
