Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован в общем машиностроении.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used in general engineering.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 1,5-3,0; марганец 0-0,3; магний 0,02-0,1; никель 0-1,0; цирконий 0,05-0,6; ванадий 0,05-0,6; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 1.5-3.0; manganese 0-0.3; magnesium 0.02-0.1; nickel 0-1.0; zirconium 0.05-0.6; vanadium 0.05-0.6; 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, никель, цирконий, ванадии, железо, дополнительно содержит церий, нитриды алюминия, бор, при следующем соотношении компонентов, мас.%: углерод 2,5-3,0; кремний 2,5-3,0; марганец 0,2-0,4; магний 0,005-0,01; никель 2,0-2,5; цирконий 0,3-0,5; ванадий 0,3-0,5; церий 0,005-0,01; нитриды алюминия 0,05-0,15; бор 0,03-0,05; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, nickel, zirconium, vanadium, iron, additionally contains cerium, aluminum nitrides, boron, in the following ratio of components, wt.%: Carbon 2.5-3, 0; silicon 2.5-3.0; manganese 0.2-0.4; magnesium 0.005-0.01; nickel 2.0-2.5; zirconium 0.3-0.5; vanadium 0.3-0.5; cerium 0.005-0.01; aluminum nitrides 0.05-0.15; boron 0.03-0.05; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Никель, ванадий и цирконий упрочняют твердый раствор. Бор стабилизирует карбиды. Благодаря присутствию магния и церия выделения графита имеют плавные очертания и не ослабляют металлическую основу чугуна. Нитриды алюминия способствуют измельчению зерна, препятствуют образованию трещин.The components present in the composition of cast iron manifest themselves as follows. Nickel, vanadium and zirconium harden the solid solution. Boron stabilizes carbides. Due to the presence of magnesium and cerium, graphite emissions are smooth and do not weaken the metal base of cast iron. Aluminum nitrides contribute to the grinding of grain, prevent the formation of cracks.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400°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 730°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400 ° C) 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 730 ° C, followed by cooling in air.
