Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей печей, тепловых агрегатов, металлургического оборудования.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 of furnaces, thermal units, metallurgical equipment.
Известен чугун следующего состава, мас.%: углерод 3,0-4,5; кремний 0,5-1,8; марганец 0,1-0,6; магний 0,03-0,1; алюминий 0,5-0,9; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 3.0-4.5; silicon 0.5-1.8; manganese 0.1-0.6; magnesium 0.03-0.1; aluminum 0.5-0.9; iron - the rest [1].
Задачей изобретения является увеличение термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, включающий углерод, кремний, марганец, магний, алюминий, железо, дополнительно содержит рений, бор, теллур, серебро при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 0,5-1,0; марганец 0,4-0,6; магний 0,0003-0,001; алюминий 0,5-0,9; рений 0,2-0,3; бор 0,06-0,1; теллур 0,003-0,008; серебро 0,003-0,008; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, magnesium, aluminum, iron, additionally contains rhenium, boron, tellurium, silver in the following ratio of components, wt.%: Carbon 3.0-3.5; silicon 0.5-1.0; manganese 0.4-0.6; magnesium 0.0003-0.001; aluminum 0.5-0.9; rhenium 0.2-0.3; boron 0.06-0.1; tellurium 0.003-0.008; silver 0.003-0.008; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Магний раскисляет сплав. Рений повышает прочность, твердость и термостойкость чугуна. Алюминий увеличивает вязкость сплава, препятствует образованию трещин при перепадах температур, снижает образование окалины. Бор и теллур стабилизируют карбиды. Бор и серебро способствуют равномерному нагреву и охлаждению чугуна.In the composition of cast iron, the components manifest themselves as follows. Magnesium deoxidizes the alloy. Rhenium increases the strength, hardness and heat resistance of cast iron. Aluminum increases the viscosity of the alloy, prevents the formation of cracks at temperature extremes, reduces the formation of scale. Boron and tellurium stabilize carbides. Boron and silver contribute to uniform heating and cooling of cast iron.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают отжигу при температуре 800-820°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into molds. Castings are annealed at a temperature of 800-820 ° C, followed by cooling in air.
