Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей двигателей, печей, 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 engine parts, furnaces, metallurgical equipment.
Известен чугун следующего состава, мас.%: углерод 3,4-4,0; кремний 2,5-3,5; марганец 0,02-0,3; хром 0,01-0,3; медь 0,3-2,0; молибден 0,05-0,5; ванадий 0,1-0,5; магний 0,02-0,05; церий 0,01-0,03; неодим 0,006-0,012; празеодим 0,003-0,007; эрбий 0,001-0,003; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 3.4-4.0; silicon 2.5-3.5; manganese 0.02-0.3; chromium 0.01-0.3; copper 0.3-2.0; molybdenum 0.05-0.5; vanadium 0.1-0.5; magnesium 0.02-0.05; cerium 0.01-0.03; neodymium 0.006-0.012; praseodymium 0.003-0.007; erbium 0.001-0.003; iron - the rest [1].
Задачей изобретения является увеличение теплостойкости 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, хром, молибден, церий, неодим, празеодим, эрбий, железо, дополнительно содержит кобальт и вольфрам при следующем соотношении компонентов, мас.%: углерод 3,4-4,0; кремний 2,5-3,5; марганец 0,4-0,8; хром 0,01-0,03; молибден 0,8-1,2; церий 0,05-0,1; неодим 0,1-0,15; празеодим 0,05-0,1; эрбий 0,05-0,1; кобальт 1,6-2,0; вольфрам 6,0-8,0; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, chromium, molybdenum, cerium, neodymium, praseodymium, erbium, iron, additionally contains cobalt and tungsten in the following ratio of components, wt.%: Carbon 3.4-4, 0; silicon 2.5-3.5; manganese 0.4-0.8; chromium 0.01-0.03; molybdenum 0.8-1.2; cerium 0.05-0.1; neodymium 0.1-0.15; praseodymium 0.05-0.1; erbium 0.05-0.1; cobalt 1.6-2.0; tungsten 6.0-8.0; 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. Хром стабилизирует карбиды. Церий, ниобий, празеодим, эрбий раскисляют сплав, способствуют образованию шаровидных выделений графита, имеющих плавные очертания и не ослабляющих металлическую основу чугуна. Молибден, кобальт, вольфрам повышают прочность, твердость и теплостойкость чугуна.In the composition of cast iron, the components manifest themselves as follows. Chrome stabilizes carbides. Cerium, niobium, praseodymium, erbium deoxidize the alloy, contribute to the formation of spherical emissions of graphite, which have smooth outlines and do not weaken the metal base of cast iron. Molybdenum, cobalt, tungsten increase the strength, hardness and heat resistance of cast iron.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
