Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован в производстве насосно-компрессорного оборудования.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used in the production of tubing equipment.
Известен чугун, содержащий, мас.%: углерод 1,6-3,0; кремний 0-1,0; марганец 0-1,2; никель 0-3,0; титан 0-2,0; алюминий 0,1-1,5; кобальт 0-5,0; бор 0,01-0,5; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1,6-3,0; silicon 0-1.0; manganese 0-1.2; nickel 0-3.0; titanium 0-2.0; aluminum 0.1-1.5; cobalt 0-5.0; boron 0.01-0.5; iron - the rest [1].
Задача изобретения - повышение твердости чугуна.The objective of the invention is to increase the hardness of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, никель, титан, алюминий, кобальт, бор, железо, дополнительно включает азот при следующем соотношении компонентов, мас.%: углерод 3,0-3,8; кремний 0,8-1,0; марганец 2,0-2,4; никель 2,2-2,6; титан 0,1-0,2; алюминий 0,3-0,4; кобальт 0,3-0,4; бор 0,03-0,05; азот 0,005-0,007; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, nickel, titanium, aluminum, cobalt, boron, iron, additionally includes nitrogen in the following ratio of components, wt.%: Carbon 3.0-3.8; silicon 0.8-1.0; manganese 2.0-2.4; nickel 2.2-2.6; titanium 0.1-0.2; aluminum 0.3-0.4; cobalt 0.3-0.4; boron 0.03-0.05; nitrogen 0.005-0.007; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Марганец обеспечивает повышенную твердость чугуна. Никель и кобальт увеличивают прочностные и пластические свойства сплава. Бор стабилизирует карбиды, увеличивает твердость сплава. Алюминий и титан образуют карбонитриды, которые способствуют измельчению зерна, повышению механических свойств чугуна.The components present in the composition of cast iron manifest themselves as follows. Manganese provides increased hardness of cast iron. Nickel and cobalt increase the strength and plastic properties of the alloy. Boron stabilizes carbides, increases alloy hardness. Aluminum and titanium form carbonitrides, which contribute to the grinding of grain, increase the mechanical properties of cast iron.
Чугун выплавляют в вагранках и отливают в песчаные формы. Отливки подвергают отжигу при температуре 500-550°С для снятия внутренних напряжений.Cast iron is smelted in cupola furnaces and cast in sand forms. Castings are annealed at a temperature of 500-550 ° C to relieve internal stresses.
