Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов, печей.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 parts of thermal units, furnaces.
Известен чугун, включающий, мас. %: углерод 1,5-4,0; кремний 1,5-6,0; марганец 0,05-2,5; магний 0-0,5; алюминий 0,1-2,0; тантал 0,1-4,0; бор 0-0,5; вольфрам 0,1-4,0; железо - остальное [1].Known cast iron, including, by weight. %: carbon 1.5-4.0; silicon 1.5-6.0; manganese 0.05-2.5; magnesium 0-0.5; aluminum 0.1-2.0; tantalum 0.1-4.0; boron 0-0.5; tungsten 0.1-4.0; 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, тантал, бор, вольфрам, железо, дополнительно включает медь и рений при следующем соотношении компонентов, мас. %: углерод 3,0-3,4; кремний 0,5-1,0; марганец 0,4-0,8; алюминий 0,03-0,05; тантал 0,9-1,3; бор 0,02-0,04; вольфрам 4,2-4,4; медь 0,9-1,3; рений 0,12-0,16; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, tantalum, boron, tungsten, iron, additionally includes copper and rhenium in the following ratio of components, wt. %: carbon 3.0-3.4; silicon 0.5-1.0; manganese 0.4-0.8; aluminum 0.03-0.05; tantalum 0.9-1.3; boron 0.02-0.04; tungsten 4.2-4.4; copper 0.9-1.3; rhenium 0.12-0.16; 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. Тантал, вольфрам, рений повышают прочность и твердость чугуна. Бор стабилизирует карбиды. Алюминий раскисляет чугун. Медь, рений, вольфрам препятствуют возникновению трещин при перепадах температур.In the composition of cast iron, the components manifest themselves as follows. Tantalum, tungsten, rhenium increase the strength and hardness of cast iron. Boron stabilizes carbides. Aluminum deoxidizes cast iron. Copper, rhenium, tungsten prevent cracking during temperature changes.
Чугун выплавляют в электропечах и отливают в подготовленные формы, предварительно нагретые до температуры 350-450°C. Отливки подвергают отжигу при температуре 720-740°C с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into prepared forms, previously heated to a temperature of 350-450 ° C. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
