Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам серого чугуна, используемого в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of gray cast iron used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 2,95-3,45; кремний 1,55-2,2; марганец 0,3-0,7; никель 0,2-0,8; барий 0,012-0,05; один и более элементов из группы церий, сурьма, олово, кобальт 0,05-0,3; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.95-3.45; silicon 1.55-2.2; manganese 0.3-0.7; nickel 0.2-0.8; barium 0.012-0.05; one or more elements from the group of cerium, antimony, tin, cobalt 0.05-0.3; 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, никель, барий, церий, кобальт, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,9-3,5; кремний 0,8-1,2; марганец 0,5-1,0; никель 1,0-1,2; барий 0,0050,01; церий 0,1-0,2; кобальт 0,5-0,7; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, nickel, barium, cerium, cobalt, iron, the components are in the following ratio, wt.%: Carbon 2.9-3.5; silicon 0.8-1.2; manganese 0.5-1.0; nickel 1.0-1.2; barium 0.0050.01; cerium 0.1-0.2; cobalt 0.5-0.7; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Никель и кобальт упрочняют твердый раствор. Кобальт придает структуре сплава мелкозернистость. Марганец тормозит выделение графита, способствует повышению твердости сплава. Барий и церий раскисляют чугун, способствуют измельчению зерна. Церий способствует нейтрализации вредной примеси серы.In the composition of cast iron, the components manifest themselves as follows. Nickel and cobalt harden the solid solution. Cobalt imparts a fine grain structure to the alloy. Manganese inhibits the release of graphite, helps to increase the hardness of the alloy. Barium and cerium deoxidize cast iron, contribute to the grinding of grain. Cerium helps to neutralize harmful sulfur impurities.
Чугун выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
