Abstract
Description
Изобретение относится к области металлургии, в частности к составам сплавов, используемых для легирования серого чугуна.The invention relates to the field of metallurgy, in particular to alloy compositions used for alloying gray cast iron.
Известен сплав для легирования чугуна, содержащий, мас. %: хром 25,0-50,0; кремний 20,0-30,0; алюминий 5,0-10,0; марганец 1,0-2,0; углерод 0,5-3,0; теллур 1,0-5,0; железо - остальное [1].Known alloy for alloying cast iron, containing, by weight. %: chromium 25.0-50.0; silicon 20.0-30.0; aluminum 5.0-10.0; manganese 1.0-2.0; carbon 0.5-3.0; tellurium 1.0-5.0; iron - the rest [1].
Задачей изобретения является повышение механических свойств чугуна, легированного сплавом.The objective of the invention is to increase the mechanical properties of cast iron alloyed with alloy.
Технический результат достигается тем, что сплав для легирования чугуна, включающий хром, кремний, алюминий, теллур, железо, дополнительно содержит кальций, магний, ванадий и молибден, при следующем соотношении компонентов, мас. %: хром 25,0-35,0; кремний 1,0-5,0; алюминий 5,0-10,0; теллур 0,2-0,4; кальций 0,03-0,05; магний 0,03-0,05; ванадий 12,2-19,5; молибден 20,0-26,5; железо - остальное.The technical result is achieved in that the alloy for alloying cast iron, including chromium, silicon, aluminum, tellurium, iron, additionally contains calcium, magnesium, vanadium and molybdenum, in the following ratio of components, wt. %: chromium 25.0-35.0; silicon 1.0-5.0; aluminum 5.0-10.0; tellurium 0.2-0.4; calcium 0.03-0.05; magnesium 0.03-0.05; vanadium 12.2-19.5; molybdenum 20.0-26.5; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Введенные в чугун компоненты, входящие в состав лигатуры проявляют себя следующим образом. Хром, кремний, молибден, ванадий повышают механические свойства чугуна. Ванадий и алюминий увеличивают вязкость сплава, препятствуют возникновению и развитию трещин. Кальций и магний раскисляют сплав. Теллур стабилизирует карбиды.The components included in the cast iron that are part of the ligature manifest themselves as follows. Chrome, silicon, molybdenum, vanadium increase the mechanical properties of cast iron. Vanadium and aluminum increase the viscosity of the alloy, prevent the occurrence and development of cracks. Calcium and magnesium deoxidize the alloy. Tellurium stabilizes carbides.
Лигатуру вводят в расплав серого чугуна в количестве 1-1,5% от его массы в желобе вагранки или в ковше. Введение лигатуры способствует повышению прочности серого чугуна на 5-7%.The ligature is introduced into the melt of gray cast iron in an amount of 1-1.5% of its mass in the cupola of the cupola or in the bucket. The introduction of ligatures helps to increase the strength of gray cast iron by 5-7%.
