Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сплавов на основе железа, которые могут быть использованы в производстве труб.The invention relates to the field of ferrous metallurgy, in particular to compositions of alloys based on iron, which can be used in the manufacture of pipes.
Известен сплав на основе железа, содержащий мас.%: углерод 0,08-0,15; кремний 0,1-0,5; марганец 0,1-0,5; хром 4,5-6,0; молибден 0,45-0,6; титан 0,4-0,7; церий 0,08-0,12; кальций 0,01-0,04; железо - остальное [1].Known iron-based alloy containing wt.%: Carbon 0.08-0.15; silicon 0.1-0.5; manganese 0.1-0.5; chrome 4.5-6.0; molybdenum 0.45-0.6; titanium 0.4-0.7; cerium 0.08-0.12; calcium 0.01-0.04; iron - the rest [1].
Задачей изобретения является повышение теплостойкости сплава.The objective of the invention is to increase the heat resistance of the alloy.
Технический результат достигается тем, что сплав на основе железа, включающий углерод, кремний, марганец, хром, молибден, титан, церий, кальций, дополнительно содержит бор и никель, причем компоненты находятся при следующем соотношении, мас. %: углерод 4,6-4,8; кремний 0,03-0,08; марганец 0,1-0,5; хром 4,5-6,0; молибден 0,2-0,3; титан 0,04-0,07; церий 2,4-2,8; кальций 0,002-0,004; бор 0,002-0,004; никель 3,0-3,5; железо - остальное.The technical result is achieved in that the alloy based on iron, including carbon, silicon, manganese, chromium, molybdenum, titanium, cerium, calcium, additionally contains boron and nickel, and the components are in the following ratio, wt. %: carbon 4.6-4.8; silicon 0.03-0.08; manganese 0.1-0.5; chrome 4.5-6.0; molybdenum 0.2-0.3; titanium 0.04-0.07; cerium 2.4-2.8; calcium 0.002-0.004; boron 0.002-0.004; nickel 3.0-3.5; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Хром, молибден, никель, бор, церий повышают теплостойкость сплава на основе железа. Бор способствует равномерному прогреву и охлаждению сплава. Никель и титан улучшают металлическую основу сплава. Никель препятствует возникновению и развитию трещин при температурных нагрузках. Кальций раскисляет сплав.Chrome, molybdenum, nickel, boron, cerium increase the heat resistance of the alloy based on iron. Boron contributes to uniform heating and cooling of the alloy. Nickel and titanium improve the metal base of the alloy. Nickel prevents the occurrence and development of cracks under temperature loads. Calcium deoxidizes the alloy.
Сплав может быть выплавлен в электропечах. Для снятия внутренних напряжений отливки отжигают при температуре 600°С.The alloy can be smelted in electric furnaces. To relieve internal stresses, castings are annealed at a temperature of 600 ° C.
