Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления деталей печей, тепловых агрегатов.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of parts of furnaces, thermal units.
Известен чугун следующего состава, мас.%: углерод 2,5-4,5; кремний 1,5-4,5; марганец 0,5-1,7; молибден 0,2-2,0; магний 0,02-0,5; медь 0,2-1,8; ниобий 0,2-2,0; цирконий 0-0,5; вольфрам 0,2-2,0; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 2.5-4.5; silicon 1.5-4.5; manganese 0.5-1.7; molybdenum 0.2-2.0; magnesium 0.02-0.5; copper 0.2-1.8; niobium 0.2-2.0; zirconium 0-0.5; tungsten 0.2-2.0; iron - the rest [1].
Задача изобретения состоит в повышении 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, молибден, магний, медь, ниобий, цирконий, железо дополнительно содержит церий при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 3,0-3,6; марганец 0,4-0,6; молибден 1,6-2,0; магний 0,001-0,002; медь 1,2-1,6; ниобий 1,2-1,6; цирконий 0,9-1,1; церий 0,4-0,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, molybdenum, magnesium, copper, niobium, zirconium, iron additionally contains cerium in the following ratio of components, wt.%: Carbon 3.0-3.6; silicon 3.0-3.6; manganese 0.4-0.6; molybdenum 1.6-2.0; magnesium 0.001-0.002; copper 1.2-1.6; niobium 1.2-1.6; zirconium 0.9-1.1; cerium 0.4-0.6; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Молибден, ниобий, цирконий и вольфрам упрочняют твердый раствор, повышают прочностные характеристики сплава, увеличивают твердость, делают его теплоустойчивым, увеличивают несущую способность деталей при ударных нагрузках и высоких температурах. Медь способствует графитизации, увеличивает содержание перлита, повышает прочность и пластичность сплава. Магний раскисляет чугун, обеспечивает мелкозернистость его структуры. Церий нейтрализует вредное влияние примесей серы, препятствует возникновению внутренних напряжений в отливках.In the composition of cast iron, the components manifest themselves as follows. Molybdenum, niobium, zirconium and tungsten harden the solid solution, increase the strength characteristics of the alloy, increase hardness, make it heat-resistant, increase the bearing capacity of parts under shock loads and high temperatures. Copper promotes graphitization, increases the content of perlite, increases the strength and ductility of the alloy. Magnesium deoxidizes cast iron, provides a fine-grained structure. Cerium neutralizes the harmful effects of sulfur impurities, prevents the occurrence of internal stresses in castings.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into molds. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
