Abstract
Description
Изобретение относится к области металлургии, в частности к составам хромистого чугуна, который может быть использован для изготовления деталей мельниц, дробилок, песковых насосов.The invention relates to the field of metallurgy, in particular to compositions of chrome cast iron, which can be used for the manufacture of parts for mills, crushers, sand pumps.
Известен чугун, включающий, мас.%: углерод 2,4-3,5; кремний 0,4-1,4; марганец 3,2-5,0; хром 16,0-24,0; цирконий 0,05-0,1; бор 0,05-0,2; железо - остальное [1].Known cast iron, including, wt.%: Carbon 2.4-3.5; silicon 0.4-1.4; manganese 3.2-5.0; chrome 16.0-24.0; zirconium 0.05-0.1; boron 0.05-0.2; iron - the rest [1].
Задача изобретения состоит в повышении прокаливаемости чугуна.The objective of the invention is to increase the hardenability of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, цирконий, бор, железо, дополнительно включает ниобий, кальций и медь при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 0,5-1,0; марганец 3,0-4,0; хром 16,0-24,0; цирконий 0,1-0,2; бор 0,1-0.2; ниобий 0,1-0,2; кальций 0,01-0,02; медь 0,1-0,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, zirconium, boron, iron, additionally includes niobium, calcium and copper in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 0.5-1.0; manganese 3.0-4.0; chrome 16.0-24.0; zirconium 0.1-0.2; boron 0.1-0.2; niobium 0.1-0.2; calcium 0.01-0.02; copper 0.1-0.2; 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 сплава. Бор стабилизирует карбиды. Ниобий и медь упрочняют твердый раствор, препятствуют развитию трещин. Кальций способствует измельчению зерна.The components present in the composition of cast iron manifest themselves as follows. Chrome and manganese provide increased hardness of the alloy. Boron stabilizes carbides. Niobium and copper harden the solid solution, prevent the development of cracks. Calcium helps grind grain.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают выдержке в течение 6-8 ч при температуре 600°С с последующим охлаждением на воздухе. Отливки воспринимают термообработку на глубину 130-150 мм.Cast iron is smelted in electric furnaces and molds are cast. The castings are exposed for 6-8 hours at a temperature of 600 ° C, followed by cooling in air. Castings perceive heat treatment to a depth of 130-150 mm.
