Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для отливки изделий, работающих в условиях термических нагрузок, например изложниц.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for casting products operating under thermal loads, such as molds.
Известен чугун следующего состава, мас. %: углерод 4,1-4,5; кремний 0,8-1,2; марганец 0,5-1,0; хром 0,12-0,3; барий 0,001-0,005; железо - остальное [1].Known cast iron of the following composition, wt. %: carbon 4.1-4.5; silicon 0.8-1.2; manganese 0.5-1.0; chrome 0.12-0.3; barium 0.001-0.005; 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, барий, железо, дополнительно содержит эрбий и алюминий, при следующем соотношении компонентов, мас. %: углерод 4,0-4,5; кремний 0,8-1,0; марганец 1,2-1,6; хром 0,1-0,15; барий 0,001-0,005; эрбий 0,15-0,3; алюминий 2,2-2,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, barium, iron, additionally contains erbium and aluminum, in the following ratio of components, wt. %: carbon 4.0-4.5; silicon 0.8-1.0; manganese 1.2-1.6; chrome 0.1-0.15; barium 0.001-0.005; erbium 0.15-0.3; aluminum 2.2-2.6; 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. Хром, эрбий, алюминий повышают термостойкость сплава. Эрбий, алюминий, барий препятствуют образованию и развитию трещин в чугунных изделиях при резких перепадах температур.In the composition of cast iron, the components manifest themselves as follows. Chrome, erbium, aluminum increase the heat resistance of the alloy. Erbium, aluminum, barium prevent the formation and development of cracks in cast iron products at sudden changes in temperature.
Чугун выплавляют в электропечах и отливают в горячие (400-500°C) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 600°C.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 600 ° C.
