Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого преимущественно для получения крупногабаритных отливок.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, used mainly for the production of large castings.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0-0,2; кальций 0-0,2; барий 0-0,2; хром 0-1,5; медь 0-4,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; aluminum 0-0.2; calcium 0-0.2; barium 0-0.2; chrome 0-1.5; copper 0-4.0; iron - the rest [1].
Задачей изобретения является повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, кальций, барий, хром, медь, железо, дополнительно содержит цинк при следующем соотношении компонентов, мас.%: углерод 2,2-3,0; кремний 1,2-1,8; марганец 0,4-0,6; алюминий 0,1-0,3; кальций 0,02-0,04; барий 0,02-0,04; хром 0,3-0,5; медь 0,6-1,0; цинк 0,01-0,03; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, calcium, barium, chromium, copper, iron, additionally contains zinc in the following ratio of components, wt.%: Carbon 2.2-3.0; silicon 1.2-1.8; manganese 0.4-0.6; aluminum 0.1-0.3; calcium 0.02-0.04; barium 0.02-0.04; chrome 0.3-0.5; copper 0.6-1.0; zinc 0.01-0.03; 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. Медь способствует графитизации, увеличивает содержание в сплаве перлита, повышает прочность. Алюминий, кальций и барий выполняют функцию раскислителей. Алюминий и цинк придают отливкам мелкозернистость.In the composition of cast iron, the components manifest themselves as follows. Chrome stabilizes carbides. Copper promotes graphitization, increases the content of perlite in the alloy, and increases strength. Aluminum, calcium and barium act as deoxidizers. Aluminum and zinc give the castings a fine grain.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
