Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован в станкостроении.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used in machine tools.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; сурьма 0-0,2; бор 0,01-0,1; свинец 0-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; antimony 0-0.2; boron 0.01-0.1; lead 0-0.2; iron - the rest [1].
Задачей изобретения является повышение износостойкости чугуна,The objective of the invention is to increase the wear resistance of cast iron,
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, сурьму, бор, свинец, железо, дополнительно включает натрий при следующем соотношении компонентов, мас.%: углерод 3,0-3,4; кремний 1,8-2,2; марганец 0,6-1,0; сурьма 0,05-0,11; бор 0,11-0,15; свинец 0,05-0,11; натрий 0,0001-0,0002; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, antimony, boron, lead, iron, additionally includes sodium in the following ratio of components, wt.%: Carbon 3.0-3.4; silicon 1.8-2.2; manganese 0.6-1.0; antimony 0.05-0.11; boron 0.11-0.15; lead 0.05-0.11; sodium 0.0001-0.0002; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение износостойкости чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Марганец обеспечивает повышенную твердость и износостойкость чугуна. Бор стабилизирует карбиды. Сурьма, свинец и натрий способствуют образованию мелкозернистой структуры сплава, уменьшают вероятность образования заусениц.The increase in wear resistance of cast iron is due to the complex effect of the components that make up its composition. Manganese provides increased hardness and wear resistance of cast iron. Boron stabilizes carbides. Antimony, lead and sodium contribute to the formation of a fine-grained alloy structure, reduce the likelihood of burrs.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отжигу при температуре 600°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay. Castings are annealed at a temperature of 600 ° C.
