Abstract
Description
Изобретение относится к области металлургии, а именно к составам серого чугуна, который может быть использован в автомобильной промышленности, в тракторном машиностроении.The invention relates to the field of metallurgy, and in particular to compositions of gray cast iron, which can be used in the automotive industry, in tractor engineering.
Известен чугун, содержащий, мас.%: углерод 1,5-4,0; кремний 0-1,5; марганец 0,05-1,5; алюминий 0,05-2,0; хром 0,02-1,5; медь 0,02-2,5; кобальт ≤5,0, титан, ниобий и ванадий ≤7,0 в сумме; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.5-4.0; silicon 0-1.5; manganese 0.05-1.5; aluminum 0.05-2.0; chrome 0.02-1.5; copper 0.02-2.5; cobalt ≤5.0, titanium, niobium and vanadium ≤7.0 in total; 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, хром, титан, алюминий, медь, ниобий, кобальт, ванадий, железо, дополнительно содержит РЗЭ и азот при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 0,8-1,2; марганец 0,8-1,2; хром 0,3-0,8; титан 0,1-0,2; алюминий 0,1-0,2; медь 0,3-0,5; ниобий 0,8-1,2; кобальт 0,8-1,2; ванадий 0,8-1,2; РЗЭ 0,1-0,2; азот 0,1-0,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, titanium, aluminum, copper, niobium, cobalt, vanadium, iron, additionally contains REE and nitrogen in the following ratio, wt.%: Carbon 2,8- 3.2; silicon 0.8-1.2; manganese 0.8-1.2; chrome 0.3-0.8; titanium 0.1-0.2; aluminum 0.1-0.2; copper 0.3-0.5; niobium 0.8-1.2; cobalt 0.8-1.2; vanadium 0.8-1.2; REE 0.1-0.2; nitrogen 0.1-0.2; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Ниобий, кобальт и ванадий упрочняют твердый раствор. Медь способствует графитизации, увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Хром стабилизирует карбиды. Алюминий и РЗЭ раскисляют чугун. Титан образует карбонитриды титана, которые способствуют повышению механических свойств чугуна и придают мелкозернистость его структуре.The components present in the composition of cast iron manifest themselves as follows. Niobium, cobalt and vanadium strengthen the solid solution. Copper promotes graphitization, increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Chrome stabilizes carbides. Aluminum and REE deoxidize cast iron. Titanium forms titanium carbonitrides, which contribute to the increase in the mechanical properties of cast iron and give a fine-grained structure.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
