Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован в энергетическом машиностроении.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used in power engineering.
Известен чугун, включающий, мас.%: углерод 2,2-3,0; кремний 0,5-0,8; марганец 0,5-0,8; хром 14,0-16,0; титан 0,3-0,5; молибден 0,2-0,6; алюминий 0,5-1,0; медь 1,5-2,0; железо - остальное [1].Known cast iron, including, wt.%: Carbon 2.2-3.0; silicon 0.5-0.8; manganese 0.5-0.8; chrome 14.0-16.0; titanium 0.3-0.5; molybdenum 0.2-0.6; aluminum 0.5-1.0; copper 1.5-2.0; 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, титан, молибден, алюминий, медь, железо, дополнительно включает ванадий и вольфрам, при следующем соотношении компонентов, мас.%: углерод 2,2-2,8; кремний 0,6-0,8; марганец 0,8-1,2; хром 14,0-16,0; титан 0,5-1,0; молибден 5,0-6,0; алюминий 0,5-1,0; медь 1,0-2,0; ванадий 1,5-2,5; вольфрам 1,5-2,5; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, titanium, molybdenum, aluminum, copper, iron, additionally includes vanadium and tungsten, in the following ratio, wt.%: Carbon 2.2-2.8 ; silicon 0.6-0.8; manganese 0.8-1.2; chrome 14.0-16.0; titanium 0.5-1.0; molybdenum 5.0-6.0; aluminum 0.5-1.0; copper 1.0-2.0; vanadium 1.5-2.5; tungsten 1.5-2.5; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Термостойкость чугуна составляет 2500-2700 циклов (при нагреве до 550°С токами высокой частоты и охлаждении на воздухе до 20°С) для всех приведенных в таблице составов.The heat resistance of cast iron is 2500-2700 cycles (when heated to 550 ° C by high frequency currents and cooled in air to 20 ° C) for all the compositions listed in the table.
В чугуне компоненты проявляют себя следующим образом. Ванадий, молибден и вольфрам упрочняют твердый раствор. Марганец и хром обеспечивают повышенную твердость чугуна. Хром и алюминий препятствуют росту окалины. Медь улучшает металлическую основу сплава, повышает прочность чугуна, препятствует развитию трещин. Титан обеспечивает мелкозернистость структуры сплава.In cast iron, the components manifest themselves as follows. Vanadium, molybdenum and tungsten harden the solid solution. Manganese and chromium provide increased hardness of cast iron. Chrome and aluminum inhibit the growth of scale. Copper improves the metal base of the alloy, increases the strength of cast iron, and prevents the development of cracks. Titanium provides a fine-grained alloy structure.
Чугун выплавляют в электропечах и отливают в песчаные формы. Отливки подвергают отпуску при температуре 200-230°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and cast in sand forms. Castings are tempered at a temperature of 200-230 ° C to relieve linear stresses.
