Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам серого чугуна, используемого в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of gray cast iron used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 0,5,0-3,0; кремний 3,6-7,0; марганец 0-10,0; хром 25,0-45,0; церий 0-0,5; алюминий 0-3,0; ниобий 0-8,0; азот 0-0,5; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 0.5.0-3.0; silicon 3.6-7.0; manganese 0-10.0; chrome 25.0-45.0; cerium 0-0.5; aluminum 0-3.0; niobium 0-8.0; nitrogen 0-0.5; 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, хром, церий, алюминий, ниобий, азот, железо, дополнительно содержит титан и вольфрам при следующем соотношении компонентов, мас.%: углерод 2,3-2,8; кремний 0,8-1,2; марганец 0,5-1,0; хром 0,5-1,0; церий 0,1-0,2; алюминий 0,3-0,5; ниобий 0,8-1,2; азот 0,05-0,1; титан 0,25-0,45; вольфрам 0,3-0,5; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, cerium, aluminum, niobium, nitrogen, iron, additionally contains titanium and tungsten in the following ratio of components, wt.%: Carbon 2.3-2.8; silicon 0.8-1.2; manganese 0.5-1.0; chrome 0.5-1.0; cerium 0.1-0.2; aluminum 0.3-0.5; niobium 0.8-1.2; nitrogen 0.05-0.1; titanium 0.25-0.45; tungsten 0.3-0.5; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Ниобий и вольфрам упрочняют твердый раствор. Хром стабилизирует карбиды. Марганец тормозит выделение графита. Алюминий и церий раскисляют чугун, способствуют измельчению зерна, при этом церий нейтрализует вредное влияние примесей серы. В химически связанном состоянии с алюминием, титаном и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали.In the composition of cast iron, the components manifest themselves as follows. Niobium and tungsten harden the solid solution. Chrome stabilizes carbides. Manganese inhibits the release of graphite. Aluminum and cerium deoxidize cast iron, contribute to the grinding of grain, while cerium neutralizes the harmful effects of sulfur impurities. In a chemically bound state with aluminum, titanium and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel.
Чугун выплавляют в электропечах и отливают в формы. Легирование титаном производят присадкой ферротитана. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast into molds. Alloying with titanium is made by the addition of ferrotitanium. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
