Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован в общем машиностроении.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in general engineering.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0;.кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; алюминий 0-0,2; кальций 0-0,2; фосфор 0-0,3; молибден 0-0,8; ниобий 0-0,2; 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; aluminum 0-0.2; calcium 0-0.2; phosphorus 0-0.3; molybdenum 0-0.8; niobium 0-0.2; iron - the rest [1].
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, медь, алюминий, кальций, фосфор, молибден ниобий, железо, дополнительно включает цинк и нитриды бария при следующем соотношении компонентов, мас.%: углерод 3,3-3,7; кремний 1,8-2,3; марганец 1,0-1,5; медь 0,8-4,2; алюминий 0,1-0,2; кальций 0,003-0,007; фосфор 0,1-0,2; молибден 4,0-4,5; ниобий 0,5-1,0; цинк 0,005-0,01; нитриды бария 0,003-0,005; железо - остальное,The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, aluminum, calcium, phosphorus, niobium molybdenum, iron, additionally includes zinc and barium nitrides in the following ratio, wt.%: Carbon 3,3-3, 7; silicon 1.8-2.3; manganese 1.0-1.5; copper 0.8-4.2; aluminum 0.1-0.2; calcium 0.003-0.007; phosphorus 0.1-0.2; molybdenum 4.0-4.5; niobium 0.5-1.0; zinc 0.005-0.01; barium nitrides 0.003-0.005; iron - the rest,
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышенная прочность чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Медь способствует графитизации и увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Молибден и ниобий упрочняют твердый раствор. Алюминий и кальций выполняют функцию раскислителей. Фосфор образует легкоплавкую эвтектику с твердыми участками. Цинк и нитриды бария придают мелкозернистость структуре сплава.The increased strength of cast iron is achieved due to the complex effect of the components included in its composition. Copper promotes graphitization and increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Molybdenum and niobium strengthen the solid solution. Aluminum and calcium act as deoxidizers. Phosphorus forms a fusible eutectic with solid areas. Zinc and barium nitrides give a fine-grained alloy structure.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast into molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
