Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления прокатных валков.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of rolling rolls.
Известен чугун следующего состава, мас. %: углерод 2,4-3,6; кремний 1,2-1,6; марганец 0,3-0,4; хром 6,6-8,9; ванадий 0,1-0,8; железо - остальное [1]. Предел прочности такого чугуна при изгибе составляет 52-59 кгс/мм2.Known cast iron of the following composition, wt. %: carbon 2.4-3.6; silicon 1.2-1.6; manganese 0.3-0.4; chrome 6.6-8.9; vanadium 0.1-0.8; iron - the rest [1]. The tensile strength of such cast iron in bending is 52-59 kgf / mm 2 .
Задачей изобретения является повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, ванадий, железо, дополнительно содержит алюминий, ниобий и цирконий при следующем соотношении компонентов, мас. %: углерод 2,4-3,6; кремний 1,2-2,6; марганец 1,5-2,5; хром 7,0-9,0; ванадий 1,0-2,0; алюминий 0,1-0,3; ниобий 1,0-1,8; цирконий 1,0-1,8; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, vanadium, iron, additionally contains aluminum, niobium and zirconium in the following ratio of components, wt. %: carbon 2.4-3.6; silicon 1.2-2.6; manganese 1.5-2.5; chrome 7.0-9.0; vanadium 1.0-2.0; aluminum 0.1-0.3; niobium 1.0-1.8; zirconium 1.0-1.8; 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. Ванадий, цирконий и ниобий повышают прочностные характеристики сплава. Ванадий и алюминий препятствуют образованию и развитию трещин в чугунных изделиях. Хром увеличивает твердость чугуна, делает его износоустойчивым.In the composition of cast iron, the components manifest themselves as follows. Vanadium, zirconium and niobium increase the strength characteristics of the alloy. Vanadium and aluminum prevent the formation and development of cracks in cast iron products. Chrome increases the hardness of cast iron, making it wear-resistant.
Чугун выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
