Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован в станкостроении, железнодорожном машиностроении, сельскохозяйственном тракторном машиностроении, автомобильной промышленности.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used in machine tools, railway engineering, agricultural tractor engineering, and the automotive industry.
Известен чугун, содержащий, мас.%: углерод 3,2-3,6; кремний 2,6-3,0; марганец 1,0-2,0; хром 0,05-0,25; РЗМ 0,1-0,15; кальций 0,005-0,05; барий 0,005-0,02; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.2-3.6; silicon 2.6-3.0; manganese 1.0-2.0; chrome 0.05-0.25; REM 0.1-0.15; calcium 0.005-0.05; barium 0.005-0.02; iron - the rest [1].
Задача изобретения - 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, хром, РЗМ, кальций, барий, железо, дополнительно содержит кобальт при следующем соотношении компонентов, мас.%: углерод 3,2-3,6; кремний 2,0-2,4; марганец 1,6-2,0; хром 0,05-0,1; РЗМ 0,25-0,35; кальций 0,01-0,015; барий 0,01-0,015; кобальт 4,0-5,0; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, rare-earth metals, calcium, barium, iron, additionally contains cobalt in the following ratio of components, wt.%: Carbon 3.2-3.6; silicon 2.0-2.4; manganese 1.6-2.0; chrome 0.05-0.1; REM 0.25-0.35; calcium 0.01-0.015; barium 0.01-0.015; cobalt 4.0-5.0; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Кальций, барий и РЗМ раскисляют сплав, способствуют измельчению зерна. Барий нейтрализует вредные влияния примесей (титана, мышьяка, свинца) на форму выделений графита. Хром стабилизирует карбиды, способствует увеличению твердости сплава. Кобальт повышает прочностные свойства сплава.In the composition of cast iron, the components manifest themselves as follows. Calcium, barium and rare-earth metals deoxidize the alloy, contribute to the grinding of grain. Barium neutralizes the harmful effects of impurities (titanium, arsenic, lead) on the form of graphite emissions. Chromium stabilizes carbides and increases the hardness of the alloy. Cobalt increases the strength properties of the alloy.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают отжигу при температуре 720-740°C с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
