Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления водопроводных труб.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 water pipes.
Известен чугун, содержащий, мас.%: углерод 0,5-3,0; кремний 3,0-7,0; марганец 0-10,0; алюминий 0-3,0; азот 0-0,5; медь 0-7,0; хром 25,0-45,0; ниобий 0-8,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 0.5-3.0; silicon 3.0-7.0; manganese 0-10.0; aluminum 0-3.0; nitrogen 0-0.5; copper 0-7.0; chrome 25.0-45.0; niobium 0-8.0; iron - the rest [1].
Задачей изобретения является повышение прочности чугунаThe objective of the invention is to increase the strength of cast iron
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, азот, медь, хром, ниобий, железо, дополнительно содержит рений при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,0-1,4; марганец 0,8-1,2; алюминий 0,2-0,3; азот 0,03-0,07; медь 0,8-1,2; хром 0,6-1,2; ниобий 0,8-1,0; рений 0,2-0,4; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, nitrogen, copper, chromium, niobium, iron, additionally contains rhenium in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 1.0-1.4; manganese 0.8-1.2; aluminum 0.2-0.3; nitrogen 0.03-0.07; copper 0.8-1.2; chrome 0.6-1.2; niobium 0.8-1.0; rhenium 0.2-0.4; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Медь усиливает графитизацию, препятствует образованию трещин, повышает пластичность сплава. Марганец тормозит выделение графита. Ниобий в сочетании с рением и хромом, стабилизирующим карбиды, упрочняют твердый раствор. Алюминий выполняет функцию раскислителя. В химически связанном состоянии с алюминием и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства чугуна.In the composition of cast iron, the components manifest themselves as follows. Copper enhances graphitization, prevents the formation of cracks, increases the ductility of the alloy. Manganese inhibits the release of graphite. Niobium in combination with rhenium and carbide stabilizing chromium strengthen the solid solution. Aluminum acts as a deoxidizer. In a chemically bound state with aluminum and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of cast iron.
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.
