Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления изделий, работающих в условиях повышенных термоциклических нагрузок.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of products operating under conditions of high thermal cyclic loads.
Известен чугун, содержащий, мас.%: углерод 2,8-3,5; кремний 1,0-1,4; марганец 0,4-0,7; хром 0,1-0,5; никель 1,8-3,5; молибден 0,2-0,5; медь 0,2-1,2; магний 0,02-0,05; ванадий 0,01-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.8-3.5; silicon 1.0-1.4; manganese 0.4-0.7; chrome 0.1-0.5; nickel 1.8-3.5; molybdenum 0.2-0.5; copper 0.2-1.2; magnesium 0.02-0.05; vanadium 0.01-0.2; iron - the rest [1].
Задачей изобретения является повышение термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, никель, молибден, медь, магний, ванадий, железо, дополнительно содержит гафний и титан при следующем соотношений компонентов, мас.%: углерод 2,4-3,2; кремний 0,6-1,0; марганец 0,6-1,0; хром 0,5-1,0; никель 3,5-4,0; молибден 2,0-3,0; медь 0,8-1,2; магний 0,04-0,08; ванадий 0,8-1,2; гафний 2,0-3,0, титан 0,5-1,0; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, nickel, molybdenum, copper, magnesium, vanadium, iron, additionally contains hafnium and titanium in the following ratio of components, wt.%: Carbon 2,4-3, 2; silicon 0.6-1.0; manganese 0.6-1.0; chrome 0.5-1.0; nickel 3.5-4.0; molybdenum 2.0-3.0; copper 0.8-1.2; magnesium 0.04-0.08; vanadium 0.8-1.2; hafnium 2.0-3.0, titanium 0.5-1.0; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.

Термостойкость чугуна обеспечивается за счет комплексного влияния компонентов, входящих в его состав. Хром стабилизирует карбиды, препятствует росту окалины. Молибден и гафний упрочняют твердый раствор. Никель препятствует возникновению и развитию трещин. Ванадий и титан улучшают металлическую основу сплава. Медь увеличивает содержание в сплаве перлита, марганец способствует его измельчению. Присутствие в чугуне магния, выполняющего функцию раскислителя, способствует измельчению зерна.Heat resistance of cast iron is ensured due to the complex effect of the components that make up its composition. Chromium stabilizes carbides, prevents the growth of scale. Molybdenum and hafnium strengthen the solid solution. Nickel prevents the occurrence and development of cracks. Vanadium and titanium improve the metal base of the alloy. Copper increases the content of perlite in the alloy, manganese contributes to its grinding. The presence of magnesium in the cast iron, which acts as a deoxidizer, contributes to the grinding of grain.
Чугун выплавляют в электропечах и отливают в горячие (400°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отжигу при температуре 900-950°C с последующим охлаждением вместе с печью.Cast iron is smelted in electric furnaces and cast into hot (400 ° C) metal molds coated with refractory clay. The castings are annealed at a temperature of 900-950 ° C, followed by cooling together with the furnace.
