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 никель, бор, медь, рений, серебро, вольфрам при следующем соотношении компонентов, мас.%: углерод 4,0-4,5; кремний 0,8-1,0; марганец 1,0-1,4; хром 0,1-0,15; барий 0,001-0,005; никель 1,0-1,4; бор 0,08-0,12; медь 0,3-0,5; рений 0,08-0,12; серебро 0,001-0,005; вольфрам 0,7-1,1; железо - остальное. В таблице приведены составы чугуна.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, barium, iron, additionally contains nickel, boron, copper, rhenium, silver, tungsten in the following ratio of components, wt.%: Carbon 4.0-4, 5; silicon 0.8-1.0; manganese 1.0-1.4; chrome 0.1-0.15; barium 0.001-0.005; nickel 1.0-1.4; boron 0.08-0.12; copper 0.3-0.5; rhenium 0.08-0.12; silver 0.001-0.005; tungsten 0.7-1.1; iron is the rest. The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Барий раскисляет сплав. Хром, вольфрам, никель, рений, медь повышают прочностные характеристики сплава, увеличивают сопротивление механическим нагрузкам при повышенных температурах. Серебро и бор способствуют равномерному прогреву и охлаждению изделий.In the composition of cast iron, the components manifest themselves as follows. Barium deoxidizes the alloy. Chromium, tungsten, nickel, rhenium, copper increase the strength characteristics of the alloy, increase resistance to mechanical stress at elevated temperatures. Silver and boron contribute to uniform heating and cooling of products.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 600°С.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.
