Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления изделий, работающих в условиях термоциклических нагрузок.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used for the manufacture of products operating under thermocyclic loads.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; алюминий 0,01-1,0; медь не более 0,2; молибден 0,01-2,0; теллур 0,001-0,05; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; aluminum 0.01-1.0; copper no more than 0.2; molybdenum 0.01-2.0; tellurium 0.001-0.05; iron - the rest [1].
Задачей изобретения является повышение 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, алюминий, медь, молибден, теллур, железо, дополнительно содержит кальций при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 0,6-0,9; марганец 0,1-0,2; алюминий 3,2-3,6; медь 2,2-2,6; молибден 0,6-0,9; теллур 0,001-0,003, кальций 0,06-0,09; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, molybdenum, tellurium, iron, additionally contains calcium in the following ratio of components, wt.%: Carbon 2,8-3,2; silicon 0.6-0.9; manganese 0.1-0.2; aluminum 3.2-3.6; copper 2.2-2.6; molybdenum 0.6-0.9; tellurium 0.001-0.003, calcium 0.06-0.09; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение термостойкости чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Молибден упрочняют твердью раствор, улучшает металлическую основу сплава. Медь способствует графитизации и увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Теллур стабилизирует карбиды. Кальций способствует получению мелкозернистой структуры чугуна.Increasing the heat resistance of cast iron is achieved due to the complex effect of the components that make up its composition. Molybdenum is hardened with a solid solution, improves the metal base of the alloy. Copper promotes graphitization and increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Tellurium stabilizes carbides. Calcium contributes to the production of a fine-grained structure of cast iron.
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.
