Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован для изготовления поршневых колец двигателей внутреннего сгорания.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used for the manufacture of piston rings of internal combustion engines.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; хром 0-1,5; ванадий 0-1,0; алюминий 0-0,2; медь 0-4,0; цирконий 0-1,0; титан 0-1,0; ниобий 0-1,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; chrome 0-1.5; vanadium 0-1.0; aluminum 0-0.2; copper 0-4.0; zirconium 0-1.0; titanium 0-1.0; niobium 0-1.0; iron - the rest [1].
Задача изобретения состоит в повышении прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что в чугуне, содержащем углерод, кремний, марганец, хром, ванадий, алюминий, медь, цирконий, титан, ниобий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,4-2,8; кремний 1,4-1,8; марганец 0,8-1,2; хром 0,8-1,2; ванадий 1,4-1,8; алюминий 0,8-1,2; медь 0,8-1,2; цирконий 0,2-0,4; титан 0,1-0,2; ниобий 0,8-1,2; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, chromium, vanadium, aluminum, copper, zirconium, titanium, niobium, iron, the components are in the following ratio, wt.%: Carbon 2.4-2.8 ; silicon 1.4-1.8; manganese 0.8-1.2; chrome 0.8-1.2; vanadium 1.4-1.8; aluminum 0.8-1.2; copper 0.8-1.2; zirconium 0.2-0.4; titanium 0.1-0.2; niobium 0.8-1.2; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна проявляется комплексное влияние входящих в него компонентов. Хром стабилизирует карбиды. Медь способствует графитизации. Марганец тормозит выделение графита, препятствует росту зерна. Ниобий и ванадий упрочняют твердый раствор. Алюминий препятствует росту окалины. Титан и цирконий способствуют измельчению зерна.The composition of cast iron manifests the complex effect of its constituent components. Chrome stabilizes carbides. Copper promotes graphitization. Manganese inhibits the release of graphite, inhibits grain growth. Niobium and vanadium harden the solid solution. Aluminum inhibits the growth of scale. Titanium and zirconium contribute to grain refinement.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 500-550°С.Cast iron is smelted in cupola furnaces, by a duplex process or in electric furnaces, and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 500-550 ° C.
