Abstract
Description
Изобретение относится к области металлургии, в частности, к составам серого чугуна, который может быть использован в транспортном машиностроении.The invention relates to the field of metallurgy, in particular, to compositions of gray cast iron, which can be used in transport 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; бор 0,005-0,02; 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; boron 0.005-0.02; 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, магний, церий, кобальт, бор, железо, дополнительно включает вольфрам при следующем соотношении компонентов, мас.%: углерод 3,0-3,4; кремний 0,8-1,2: марганец 0,2-0,4; магний 0,008-0,012; церий 0,2-0,25; кобальт 0,2-0,4; бор 0,05-0,1; вольфрам 0,5-0,7; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, cerium, cobalt, boron, iron, further includes tungsten in the following ratio of components, wt.%: Carbon 3.0-3.4; silicon 0.8-1.2: manganese 0.2-0.4; magnesium 0.008-0.012; cerium 0.2-0.25; cobalt 0.2-0.4; boron 0.05-0.1; tungsten 0.5-0.7; iron is the rest.
В таблице приведены составы чугуна.The 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. Церий нейтрализует вредное влияние примесей серы. Бор стабилизирует карбиды, увеличивает твердость сплава. Кобальт улучшает металлическую основу сплава, упрочняет твердый раствор. Вольфрам увеличивает твердость и прочность чугуна.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. Cerium neutralizes the harmful effects of sulfur impurities. Boron stabilizes carbides, increases alloy hardness. Cobalt improves the metal base of the alloy, strengthens the solid solution. Tungsten increases the hardness and strength of cast iron.
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°С 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.
