Abstract
Description
Изобретение относится к области металлургии, в частности к составам серного чугуна, который может быть использован в автомобильной промышленности, тракторном машиностроении.The invention relates to the field of metallurgy, in particular to compositions of sulfur cast iron, which can be used in the automotive industry, tractor engineering.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0,02; ниобий 0-0,1; цирконий 0-0,1; ванадий 0-1,0; медь 0-4,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; aluminum 0.02; niobium 0-0.1; zirconium 0-0.1; vanadium 0-1.0; copper 0-4.0; 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 чугун, содержащий углерод, кремний, марганец, алюминий, ниобий, цирконий, ванадий, медь, железо, дополнительно содержит гафний при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,0-1,5; марганец 0,5-1,0; алюминий 0,25-0,45; ниобий 0,25-0,45; цирконий 0,15-0,25; ванадий 0,25-0,45; медь 2,8-3,2; гафний 0,25-0,45; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, niobium, zirconium, vanadium, copper, iron, additionally contains hafnium in the following ratio of components, wt.%: Carbon 2.8-3.2; silicon 1.0-1.5; manganese 0.5-1.0; aluminum 0.25-0.45; niobium 0.25-0.45; zirconium 0.15-0.25; vanadium 0.25-0.45; copper 2.8-3.2; hafnium 0.25-0.45; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Гафний в сочетании с ниобием упрочняют твердый раствор. Алюминий и ванадий повышает вязкость и пластичность сплава, улучшают его структуру. Марганец тормозит выделение графита. Медь усиливает графитизацию и увеличивает содержание в сплаве перлита. Цирконий способствует измельчению перлита.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. Hafnium in combination with niobium strengthen the solid solution. Aluminum and vanadium increase the viscosity and ductility of the alloy, improve its structure. Manganese inhibits the release of graphite. Copper enhances graphitization and increases the content of perlite in the alloy. Zirconium contributes to the grinding of perlite.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают нормализации при температуре 900-950°C и отпуску при температуре 200-350°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 200-350 ° C.
