Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован в железнодорожном машиностроении.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in railway engineering.
Известен чугун, содержащий, мас.%: углерод 3,2-3,8; кремний 2,6-3,2; марганец 0,2-0,7; магний 0,03-0,07; церий 0,02-0,05; кобальт 0,03-0,15; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.2-3.8; silicon 2.6-3.2; manganese 0.2-0.7; magnesium 0.03-0.07; cerium 0.02-0.05; cobalt 0.03-0.15; 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 в чугуне, содержащем углерод, кремний, марганец, магний, церий, кобальт, бор, железо, компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,2-0,4; магний 0,001-0,002; церий 0,06-0,1; кобальт 0,3-0,7; бор 0,12-0,18; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, magnesium, cerium, cobalt, boron, iron, the components are in the following ratio, wt.%: Carbon 3.0-3.4; silicon 0.8-1.2; manganese 0.2-0.4; magnesium 0.001-0.002; cerium 0.06-0.1; cobalt 0.3-0.7; boron 0.12-0.18; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Церий и магний способствуют образованию шаровидных выделений графита, имеющих плавные очертания и не ослабляющих металлическую основу чугуна. Бор стабилизирует карбиды, увеличивает твердость сплава. Кобальт улучшает металлическую основу сплава, упрочняет твердый раствор.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Cerium and magnesium contribute to the formation of spherical emissions of graphite, which have smooth outlines and do not weaken the metal base of cast iron. Boron stabilizes carbides, increases alloy hardness. Cobalt improves the metal base of the alloy, strengthens the solid solution.
Чугун выплавляют в электропечах и отливают формы. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием (сплавами магния) и высококремнистым ферросилицием. Отливки подвергают сфероидизирующему отжигу при температуре 720-740°C с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium (magnesium alloys) and high-silicon ferrosilicon. The castings are subjected to spheroidizing annealing at a temperature of 720-740 ° C, followed by cooling in air.
