Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован в автомобилестроении.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used in the automotive industry.
Известен чугун, включающий, мас.%: углерод 3,2-3,8; кремний 2,6-3,0; марганец 0,2-0,7; магний 0,03-0,07; медь 0,71-1,1; церий 0,002-0,05; ниобий 0,005-0,21; молибден 0,8-1,1; алюминий 0,03-0,1; никель 0,4-1,2; железо - остальное [1].Known cast iron, including, wt.%: Carbon 3.2-3.8; silicon 2.6-3.0; manganese 0.2-0.7; magnesium 0.03-0.07; copper 0.71-1.1; cerium 0.002-0.05; niobium 0.005-0.21; molybdenum 0.8-1.1; aluminum 0.03-0.1; nickel 0.4-1.2; 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 чугун, содержащий углерод, кремний, марганец, магний, медь, церий, ниобий, молибден, алюминий, никель, железо, дополнительно включает бор и азот при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,8-2,2; марганец 0,8-1,2; магний 0,03-0,08; медь 0,8-1,2; церий 0,08-0,12; ниобий 0,08-0,12; молибден 0,8-1,2; алюминий 0,08-0,12; никель 0,8-1,2; бор 0,08-0,12; азот 0,08-0,12; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, copper, cerium, niobium, molybdenum, aluminum, nickel, iron, additionally includes boron and nitrogen in the following ratio of components, wt.%: Carbon 2.8- 3.2; silicon 1.8-2.2; manganese 0.8-1.2; magnesium 0.03-0.08; copper 0.8-1.2; cerium 0.08-0.12; niobium 0.08-0.12; molybdenum 0.8-1.2; aluminum 0.08-0.12; nickel 0.8-1.2; boron 0.08-0.12; nitrogen 0.08-0.12; 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. Никель увеличивает прочностные и пластические свойства сплава. Молибден повышает прочностные характеристики чугуна, твердость. Бор стабилизирует карбиды в химически связанном состоянии с алюминием и ниобием, азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства чугуна. Медь способствует графитизации. Магний и церий раскисляют сплав.In the composition of cast iron, the components manifest themselves as follows. Nickel increases the strength and plastic properties of the alloy. Molybdenum increases the strength characteristics of cast iron, hardness. Boron stabilizes carbides in a chemically bonded state with aluminum and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of cast iron. Copper promotes graphitization. Magnesium and cerium deoxidize the alloy.
Чугун выплавляют в вагранках и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is melted in cupolas and cast into hot (400-450 ° С) metal molds coated with refractory clay. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
