Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей печей, конфорок газовых и электрических плит.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of parts for furnaces, burners of gas and electric stoves.
Известен чугун, содержащий, мас.%: углерод 3,0-4,5; кремний 0,5-0,8;Known cast iron, containing, wt.%: Carbon 3.0-4.5; silicon 0.5-0.8;
марганец 0,1-0,6; магний 0,03-0,1; алюминий 0,5-0,9; железо - остальное [1].manganese 0.1-0.6; magnesium 0.03-0.1; aluminum 0.5-0.9; iron - the rest [1].
Известен также чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,5-3,5; марганец 0,2-1,5; магний 0,02-0,1; алюминий 0-2,0; хром 0-3,0; железо - остальное [2].Also known is cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.5-3.5; manganese 0.2-1.5; magnesium 0.02-0.1; aluminum 0-2.0; chrome 0-3.0; iron - the rest [2].
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, алюминий, хром, железо, дополнительно содержит кобальт при следующем соотношении компонентов, мас.%: углерод 3,0-3,8; кремний 0,8-1,2; марганец 0,4-0,8; магний 0,003-0,008; алюминий 0,3-0,5; хром 0,8-1,2; кобальт 0,8-1,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, aluminum, chromium, iron, additionally contains cobalt in the following ratio of components, wt.%: Carbon 3.0-3.8; silicon 0.8-1.2; manganese 0.4-0.8; magnesium 0.003-0.008; aluminum 0.3-0.5; chrome 0.8-1.2; cobalt 0.8-1.2; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна проявляется комплексное влияние входящих в него компонентов. Хром стабилизирует карбиды. Марганец тормозит выделение графита, препятствует росту зерна. Магний выполняет функцию раскислителя, способствует получению мелкозернистой структуры. Кобальт способствует упрочнению твердого раствора, улучшает металлическую основу структуры чугуна, что способствует повышению его термостойкости.The composition of cast iron manifests the complex effect of its constituent components. Chrome stabilizes carbides. Manganese inhibits the release of graphite, inhibits grain growth. Magnesium acts as a deoxidizing agent, contributes to obtaining a fine-grained structure. Cobalt contributes to the hardening of the solid solution, improves the metal base of the structure of cast iron, which helps to increase its heat resistance.
Чугун выплавляют в электропечах и отливают в сырые песчаные формы. Для снятия литейных напряжений чугун подвергают низкотемпературному отжигу при 550-650°С.Cast iron is smelted in electric furnaces and cast in raw sand forms. To relieve foundry stresses, cast iron is subjected to low-temperature annealing at 550-650 ° С.
