Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам хромистого 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 chrome cast iron, which can be used in the production of tubing equipment.
Известен чугун, содержащий, мас.%: углерод 1,0-4,0; кремний 0,1-2,5; марганец 0,1-15,0; хром 0-40,0; никель 0-5,0; медь 0-5,0; бор 0-2,0; ванадий 0-5,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.0-4.0; silicon 0.1-2.5; manganese 0.1-15.0; chrome 0-40.0; nickel 0-5.0; copper 0-5.0; boron 0-2.0; vanadium 0-5.0; iron - the rest [1].
Задача изобретения - повышение твердости и прочности чугуна.The objective of the invention is to increase the hardness and strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, никель, медь, бор, ванадий, железо, дополнительно содержит титан, азот и кальций, при следующем соотношении компонентов, мас.%: углерод 3,0-3,8; кремний 0,5-1,0; марганец 6,0-8,0; хром 16,0-20,0; никель 1,0-2,0; медь 0,8-1,2; бор 0,1-0,3; ванадий 0,5-1,0; титан 1,0-1,5; азот 0,1-0,3; кальций 0,003-0,008; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, nickel, copper, boron, vanadium, iron, additionally contains titanium, nitrogen and calcium, with the following ratio of components, wt.%: Carbon 3.0-3 ,8; silicon 0.5-1.0; manganese 6.0-8.0; chrome 16.0-20.0; nickel 1.0-2.0; copper 0.8-1.2; boron 0.1-0.3; vanadium 0.5-1.0; titanium 1.0-1.5; nitrogen 0.1-0.3; calcium 0.003-0.008; 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. Хром и марганец обеспечивают повышенную твердость чугуна. Никель и медь улучшают металлическую основу сплава. Бор стабилизирует карбиды. Ванадий, кальций и титан, образующий карбонитриды, способствуют повышению механических свойств чугуна и придают мелкозернистость его структуре.The components present in the composition of cast iron manifest themselves as follows. Chrome and manganese provide increased hardness of cast iron. Nickel and copper improve the metal base of the alloy. Boron stabilizes carbides. Vanadium, calcium and titanium, which forms carbonitrides, contribute to the increase in the mechanical properties of cast iron and impart fine-grained structure.
Чугун выплавляют в вагранках и отливают в песчаные формы. Отливки подвергают термообработке при температуре 200-230°С.Cast iron is smelted in cupola furnaces and cast in sand forms. Castings are subjected to heat treatment at a temperature of 200-230 ° C.
