Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, который может быть использован в качестве материала для изготовления деталей тракторов и сельхозмашин, автомобилей, текстильных машин, судов, котлов, насосов.The invention relates to the field of metallurgy and relates to compositions of cast iron, which can be used as material for the manufacture of parts of tractors and agricultural machines, automobiles, textile machines, ships, boilers, pumps.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; ниобий 0-1,0; алюминий 0-0,2; молибден 0-0,8; ванадий 0-1,0; бор 0-1,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; copper 0-4.0; niobium 0-1.0; aluminum 0-0.2; molybdenum 0-0.8; vanadium 0-1.0; boron 0-1.0; iron - the rest [1].
Задача изобретения состоит в повышении прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что ковкий чугун, содержащий углерод, кремний, марганец, медь, ниобий, алюминий, молибден, ванадий, бор, железо, дополнительно включает магний и иттрий, при следующем соотношении компонентов, мас.%: углерод 2,0-2,5; кремний 1,0-1,5; марганец 0,5-1,0; медь 0,3-0,5; ниобий 0,3-0,5; алюминий 0,1-0,2; молибден 3,0-4,0; ванадий 0,3-0,5; бор 0,03-0,05; магний 0,03-0,05; иттрий 0,03-0,05; железо - остальное.The technical result is achieved by the fact that malleable cast iron containing carbon, silicon, manganese, copper, niobium, aluminum, molybdenum, vanadium, boron, iron, additionally includes magnesium and yttrium, with the following ratio of components, wt.%: Carbon 2.0- 2.5; silicon 1.0-1.5; manganese 0.5-1.0; copper 0.3-0.5; niobium 0.3-0.5; aluminum 0.1-0.2; molybdenum 3.0-4.0; vanadium 0.3-0.5; boron 0.03-0.05; magnesium 0.03-0.05; yttrium 0.03-0.05; iron is the rest.
В таблице приведены составы ковкого чугуна.The table shows the compositions of malleable cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Бор стабилизирует карбиды. Молибден, ниобий и ванадий упрочняют твердый раствор. Медь улучшает металлическую основу сплава. Алюминий, магний и иттрий раскисляют чугун, придают мелкозернистость его структуре.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Boron stabilizes carbides. Molybdenum, niobium and vanadium strengthen the solid solution. Copper improves the metal base of the alloy. Aluminum, magnesium and yttrium deoxidize cast iron, give a fine-grained structure.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Температура расплава при заливке литейных форм должна быть не ниже 1320°С. Отливки подлежат термической обработке: 1 стадия - отжиг при температуре 950-1060°С в течение 12-16 ч; 2 стадия - отжиг при температуре 700-720°С в течение 8-12 ч с последующим охлаждением вместе с печью.Cast iron is smelted in cupola furnaces, by a duplex process or in electric furnaces, and cast into hot (400-450 ° C) metal molds coated with refractory clay. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. The temperature of the melt when casting molds should be at least 1320 ° C. Castings are subject to heat treatment: stage 1 - annealing at a temperature of 950-1060 ° C for 12-16 hours; Stage 2 - annealing at a temperature of 700-720 ° C for 8-12 hours, followed by cooling together with the furnace.
