Abstract
Description
Изобретение относится к области черной металлургии, а именно, к составам белого чугуна, который может быть использован, например, для изготовления прокатных валков, деталей песковых насосов.The invention relates to the field of ferrous metallurgy, and in particular, to compositions of white cast iron, which can be used, for example, for the manufacture of rolling rolls, parts of sand pumps.
Известен чугун следующего состава, мас.%: углерод 2,4-3,6; кремний 1,2-2,6; марганец 0,3-4,0; 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 1.2-2.6; manganese 0.3-4.0; 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 гафний и бор, при следующем соотношении компонентов, мас.%: углерод 2,4-3,4; кремний 1,4-1,6; марганец 0,8-1,2; хром 7,0-9,0; ванадий 0,6-0,8; гафний 0,4-0,6; бор 0,04-0,08; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, vanadium, iron, additionally contains hafnium and boron, in the following ratio of components, wt.%: Carbon 2,4-3,4; silicon 1.4-1.6; manganese 0.8-1.2; chrome 7.0-9.0; vanadium 0.6-0.8; hafnium 0.4-0.6; boron 0.04-0.08; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышенная прочность чугуна достигается за счет мелкозернистой структуры сплава и комплексного влияния компонентов, входящих в его состав. Гафний упрочняет твердый раствор. Хром и бор стабилизируют карбиды. Ванадий выполняет функцию раскислителя.The increased strength of cast iron is achieved due to the fine-grained structure of the alloy and the complex influence of the components included in its composition. Hafnium strengthens the solid solution. Chrome and boron stabilize carbides. Vanadium acts as a deoxidizing agent.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С.Cast iron is smelted in electric furnaces and cast into molds. The castings are subjected to low-temperature annealing at a temperature of 600 ° C.
