Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления коленчатых валов, цилиндров, рам, корпусов, маховиков, зубчатых колес, поршней и других изделий.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of crankshafts, cylinders, frames, housings, flywheels, gears, pistons and other products.
Известен чугун следующего состава, 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 of the following composition, wt.%: 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].
Известен чугун следующего состава, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0-0,2; ванадий 0-1,0; молибден 0-0,8; железо - остальное.Known cast iron of the following composition, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; aluminum 0-0.2; vanadium 0-1.0; molybdenum 0-0.8; iron is the rest.
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, ванадий, молибден, железо, дополнительно содержит азот, при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 0,2-0,4; марганец 0,8-1,2; алюминий 0,05-0,15; ванадий 1,4-1,8; молибден 2,5-3,5; азот 0,04-0,08; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, vanadium, molybdenum, iron, additionally contains nitrogen, with the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 0.2-0.4; manganese 0.8-1.2; aluminum 0.05-0.15; vanadium 1.4-1.8; molybdenum 2.5-3.5; nitrogen 0.04-0.08; iron is the rest.
Повышенная прочность чугуна достигается за счет мелкозернистой структуры сплава и комплексного влияния компонентов, входящих в его состав. Молибден и ванадий упрочняют твердый характер. Марганец стабилизирует карбиды. Алюминий выполняет функцию раскислителя. Азот, образуя карбонитраты, обеспечивает мелкозернистость структуры чугуна.The increased strength of cast iron is achieved due to the fine-grained structure of the alloy and the complex influence of the components included in its composition. Molybdenum and vanadium strengthen the solid character. Manganese stabilizes carbides. Aluminum acts as a deoxidizer. Nitrogen, forming carbonitrates, provides a fine-grained structure of cast iron.
Чугун выплавляют в электропечах и отливают в формы. 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 molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
