Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%; углерод 2,0-2,8; кремний 0,7-2,5; марганец 0,3-1,2; хром 0,1-1,0; барий 0-0,2; молибден 0-0,7; никель 0-3,0, кальций 0-0,2; железо - остальное [1].Known cast iron, containing, wt.%; carbon 2.0-2.8; silicon 0.7-2.5; manganese 0.3-1.2; chrome 0.1-1.0; barium 0-0.2; molybdenum 0-0.7; nickel 0-3.0; calcium 0-0.2; iron - the rest [1].
Задачей изобретения является повышение термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, барий, молибден, никель, кальций, железо, дополнительно включает медь, бор, гафний при следующем соотношении компонентов, мас.%: углерод 2,0-2,8; кремний 0,8-1,2, марганец 0,8-1,2, хром 0,1-0,2; барий 0,001-0,002; молибден 1,5-1,9; никель 4,0-4,5; кальций 0,001-0,002; медь 0,3-0,7; бор 0,1-0,15; гафний 0,2-0,3; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, barium, molybdenum, nickel, calcium, iron, additionally includes copper, boron, hafnium in the following ratio of components, wt.%: Carbon 2.0-2, 8; silicon 0.8-1.2, manganese 0.8-1.2, chromium 0.1-0.2; barium 0.001-0.002; molybdenum 1.5-1.9; nickel 4.0-4.5; calcium 0.001-0.002; copper 0.3-0.7; boron 0.1-0.15; hafnium 0.2-0.3; 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. Хром стабилизирует карбиды, способствует повышению твердости чугуна, препятствует росту окалины. Гафний, молибден и никель улучшают металлическую основу сплава, препятствуют возникновению и развитию трещин при перепадах температур. Кальций и барий выполняют функцию раскислителей. Медь и бор способствуют равномерному прогреву чугунных изделий, что также предупреждает возникновение трещин.In the composition of cast iron, the components manifest themselves as follows. Chromium stabilizes carbides, increases the hardness of cast iron, and prevents the growth of scale. Hafnium, molybdenum and nickel improve the metal base of the alloy, prevent the occurrence and development of cracks at temperature extremes. Calcium and barium act as deoxidizers. Copper and boron contribute to uniform heating of cast iron products, which also prevents the occurrence of cracks.
Чугун выплавляют в вагранках и отливают в песчаные формы. Температура расплава при заливке литейных форм должна быть не ниже 1330°C. Отливки подвергают отжигу при температуре 720-740°C с последующим охлаждением на воздухе.Cast iron is smelted in cupola furnaces and cast in sand forms. The melt temperature when casting molds should not be lower than 1330 ° C. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
