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 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; хром 0-1,5; барий 0-0,2; олово 0-0,5; медь 0-4,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; chrome 0-1.5; barium 0-0.2; tin 0-0.5; copper 0-4.0; 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, олово, медь, железо, дополнительно включает ниобий при следующем соотношении компонентов, мас.%: углерод 3,6-4,2; кремний 0,8-1,2; марганец 2,8-3,2; хром 0,1-0,2; барий 0,007-0,011; олово 0,007-0,011; медь 4,8-5,2; ниобий 0,4-0,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, barium, tin, copper, iron, further includes niobium in the following ratio of components, wt.%: Carbon 3,6-4,2; silicon 0.8-1.2; manganese 2.8-3.2; chrome 0.1-0.2; barium 0.007-0.011; tin 0.007-0.011; copper 4.8-5.2; niobium 0.4-0.6; 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. Барий раскисляет чугун. Олово обеспечивает сплаву мелкозернистость. Медь способствует равномерному прогреву и охлаждению изделий. Ниобий препятствует образованию и развитию трещин при перепадах температур.In the composition of cast iron, the components manifest themselves as follows. Chrome stabilizes carbides. Barium deoxidizes cast iron. Tin provides the alloy with fine grain. Copper promotes uniform heating and cooling of products. Niobium prevents the formation and development of cracks at temperature extremes.
Чугун выплавляют в электропечах и отливают в песчаные формы. Температура расплава при заливке литейных форм должна быть не ниже 1330°С. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast in sand forms. The temperature of the melt when casting molds should be at least 1330 ° C. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
