Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого для изготовления деталей тепловых агрегатов, двигателей, металлургического оборудования.The invention relates to the field of ferrous metallurgy, in particular to the compositions of cast iron used for the manufacture of parts of thermal units, engines, metallurgical equipment.
Известен чугун, содержащий, мас.%: углерод 3,4-4,0; кремний 1,8-2,0; марганец 0,15-0,2; иттрий 0,01-0,015; РЗМ 0,15-0,25; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.4-4.0; silicon 1.8-2.0; manganese 0.15-0.2; yttrium 0.01-0.015; REM 0.15-0.25; 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, РЗМ, железо, дополнительно содержит алюминий, ванадий, хром при следующем соотношении компонентов, мас.%: углерод 3,5-4,0; кремний 1,5-2,0; марганец 0,5-1,0; РЗМ 0,15-0,25; алюминий 0,1-0,3; ванадий 0,4-0,8; хром 1,0-1,8; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, rare-earth metals, iron, additionally contains aluminum, vanadium, chromium in the following ratio of components, wt.%: Carbon 3,5-4,0; silicon 1.5-2.0; manganese 0.5-1.0; REM 0.15-0.25; aluminum 0.1-0.3; vanadium 0.4-0.8; chrome 1.0-1.8; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Термостойкость чугуна (нагрев до 550°С токами высокой частоты с последующим охлаждением в воде) составит - 450 циклов для всех приведенных в таблице составов.The heat resistance of cast iron (heating to 550 ° C by high-frequency currents, followed by cooling in water) will be - 450 cycles for all the compositions listed in the table.
Повышение термостойкости чугуна достигается за счет комплексного влияния входящих в его состав компонентов. Карбиды стабилизируются хромом. Ванадий упрочняет твердый раствор. Алюминий выполняет функцию раскислителя. РЗМ способствуют измельчению зерна, нейтрализуют вредное влияние примесей серы.Improving the heat resistance of cast iron is achieved due to the complex effect of its constituent components. Carbides are stabilized by chromium. Vanadium strengthens the solid solution. Aluminum acts as a deoxidizer. REM contribute to the grinding of grain, neutralize the harmful effects of sulfur impurities.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is melted in electric furnaces and cast in molds. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
