Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован, например, для изготовления изделий, эксплуатируемых при повышенных температурах и механических нагрузках.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used, for example, for the manufacture of products operated at elevated temperatures and mechanical loads.
Известен чугун, содержащий, мас.%: углерод 3,6-3,9; кремний 0,35-0,85; марганец 1,4-1,9; хром 0,05-0,3; никель 0,3-0,8; титан 0,01-0,05; медь 1,8-2,6; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.6-3.9; silicon 0.35-0.85; manganese 1.4-1.9; chrome 0.05-0.3; nickel 0.3-0.8; titanium 0.01-0.05; copper 1.8-2.6; iron - the rest [1].
Задачей изобретения является увеличение сопротивления чугуна кручению при повышенных температурах.The objective of the invention is to increase the resistance of cast iron to torsion at elevated temperatures.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, никель, титан, медь, железо, дополнительно включает ниобий и вольфрам, при следующем соотношении компонентов, мас.%: углерод 3,2-3,6; кремний 0,4-0,8; марганец 1,5-2,0; хром 4,0-5,0; никель 0,3-0,8; титан 0,1-0,2; медь 0,1-0,3; ниобий 3,0-4,0; вольфрам 0,3-0,5; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, nickel, titanium, copper, iron, additionally includes niobium and tungsten, in the following ratio, wt.%: Carbon 3,2-3,6; silicon 0.4-0.8; manganese 1.5-2.0; chrome 4.0-5.0; nickel 0.3-0.8; titanium 0.1-0.2; copper 0.1-0.3; niobium 3.0-4.0; tungsten 0.3-0.5; 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, вольфрам и марганец обеспечивают твердость чугуна при повышенных температурах. Хром препятствует росту окалины. Никель, вольфрам и ниобий упрочняют твердый раствор. Медь способствует графитизации. Титан придает мелкозернистость структуре сплава.In the composition of cast iron, the components manifest themselves as follows. Chrome, tungsten and manganese provide cast iron hardness at elevated temperatures. Chrome inhibits the growth of scale. Nickel, tungsten and niobium strengthen the solid solution. Copper promotes graphitization. Titanium gives a fine grain structure to the alloy.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают центробежным способом в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.Cast iron is smelted in cupola furnaces, by a duplex process or in electric furnaces, and centrifugally cast in hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
