Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован для отливки изделий сложной конфигурации.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used for casting products of complex configuration.
Известен чугун, включающий, мас.%: углерод 4,0-4,2; кремний 0,5-1,0; марганец 0,005-0,04; церий 0,0075-0,02; железо - остальное [1]. Жидкотекучесть такого чугуна составляет 490-540 мм.Known cast iron, including, wt.%: Carbon 4.0-4.2; silicon 0.5-1.0; manganese 0.005-0.04; cerium 0.0075-0.02; iron - the rest [1]. The fluidity of such cast iron is 490-540 mm.
Задача изобретения состоит в повышении жидкотекучести чугуна.The objective of the invention is to increase the fluidity of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, церий, дополнительно включает бор, при следующем соотношении компонентов, мас.%: углерод 3,8-4,2; кремний 0,4-0,8; марганец 0,05-0,1; церий 0,25-0,35; бор 0,25-0,35; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, cerium, further includes boron, with the following ratio of components, wt.%: Carbon 3,8-4,2; silicon 0.4-0.8; manganese 0.05-0.1; cerium 0.25-0.35; boron 0.25-0.35; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение жидкотекучести чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Бор повышает твердость и износостойкость сплава, стабилизирует карбиды. Марганец упрочняет твердый раствор, способствует измельчению зерна. Церий раскисляет чугун, способствует образованию шаровидных выделений графита, которые имеют плавные очертания и не ослабляют металлическую основу чугунаThe increase in the fluidity of cast iron is due to the complex effect of the components that make up its composition. Boron increases the hardness and wear resistance of the alloy, stabilizes carbides. Manganese strengthens the solid solution, contributes to the grinding of grain. Cerium deoxidizes cast iron, promotes the formation of spherical emissions of graphite, which have smooth outlines and do not weaken the metal base of cast iron
Чугун выплавляют в электропечах и отливают формы. Температура расплава при заливке литейных форм должна быть не ниже 1320°С. 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. The temperature of the melt when casting molds should be at least 1320 ° C. The castings are subjected to spheroidizing annealing at a temperature of 720-740 ° C, followed by cooling in air.
