Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован в станкостроении, железнодорожном машиностроении, сельскохозяйственном тракторном машиностроении, автомобильной промышленности.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used in machine tools, railway engineering, agricultural tractor engineering, and the automotive industry.
Известен чугун с вермикулярным графитом, содержащий, мас.%: углерод 3,2-3,6; кремний 2,6-3,0; марганец 1,0-2,0; хром 0,05-0,25; РЗМ 0,1-0,15; кальций 0,005-0,05; барий 0,005-0,02; железо - остальное [1].Known cast iron with vermicular graphite, containing, wt.%: Carbon 3.2-3.6; silicon 2.6-3.0; manganese 1.0-2.0; chrome 0.05-0.25; REM 0.1-0.15; calcium 0.005-0.05; barium 0.005-0.02; iron - the rest [1].
Задача изобретения - повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун с вермикулярным графитом, содержащий углерод, кремний, марганец, кальций, РЗМ, барий, хром, железо, дополнительно содержит магний, медь, цирконий при следующем соотношении компонентов, мас.%: углерод 2,8-3,6; кремний 2,0-3,0; марганец 0,6-1,0; кальций 0,005-0,01; РЗМ 0,2-0,4; барий 0,003-0,005; хром 1,0-2,0; магний 0,005-0,01; медь 0,02-0,04; цирконий 1,0-2,0; железо - остальное.The technical result is achieved by the fact that cast iron with vermicular graphite containing carbon, silicon, manganese, calcium, rare-earth metals, barium, chromium, iron, additionally contains magnesium, copper, zirconium in the following ratio, wt.%: Carbon 2,8-3 , 6; silicon 2.0-3.0; manganese 0.6-1.0; calcium 0.005-0.01; REM 0.2-0.4; barium 0.003-0.005; chrome 1.0-2.0; magnesium 0.005-0.01; copper 0.02-0.04; zirconium 1.0-2.0; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
ТаблицаTable
В чугуне выделения графита имеют шаровидную форму, что достигается введением в его состав магния, кальция, РМЗ. Барий нейтрализует вредные влияния примесей (титана, мышьяка, свинца) на форму выделений графита. Медь, в указанном количестве, не препятствует образованию выделений графита шаровидной формы, кроме того, несколько увеличивает содержание в сплаве перлита. Хром стабилизирует карбиды, упрочняет твердый раствор. Цирконий способствует измельчению зерна.In cast iron, graphite precipitates have a spherical shape, which is achieved by introducing magnesium, calcium, and RMZ into its composition. Barium neutralizes the harmful effects of impurities (titanium, arsenic, lead) on the form of graphite emissions. Copper, in the indicated amount, does not prevent the formation of spherical graphite precipitates, in addition, it slightly increases the content of perlite in the alloy. Chromium stabilizes carbides, strengthens a solid solution. Zirconium contributes to grain refinement.
Чугун выплавляют в электропечах и отливают формы. При выплавке чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Отливки подвергают сфероидизирующему отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. During smelting, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. The castings are subjected to spheroidizing annealing at a temperature of 720-740 ° C, followed by cooling in air.
