Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован, например, в энергетическом машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used, for example, in power engineering.
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 в чугуне, содержащем углерод, кремний, марганец, молибден, магний, медь, ниобий, цирконий, вольфрам, железо, компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,6; кремний 3,0-3,6; марганец 0,4-0,6; молибден 0,1-0,15; магний 0,001-0,002; медь 2,0-2,4, ниобий 0,1-0,15; цирконий 1,1-1,6; вольфрам 2,2-2,6; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, molybdenum, magnesium, copper, niobium, zirconium, tungsten, iron, the components are in the following ratio, wt.%: Carbon 3.0-3.6; silicon 3.0-3.6; manganese 0.4-0.6; molybdenum 0.1-0.15; magnesium 0.001-0.002; copper 2.0-2.4, niobium 0.1-0.15; zirconium 1.1-1.6; tungsten 2.2-2.6; iron is the rest.
В таблице приведены составы чугунаThe 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.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.
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.
