Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used for the manufacture of parts of thermal units.
Известен чугун, включающий, мас.%: углерод 2,5-3,4; кремний 1,0-1,5; марганец 0,2-1,0; магний 0,08-0,1; алюминий 1,5-2,5; медь 0,01-0,03; азот 0,01-0,03; железо - остальное [1].Known cast iron, including, wt.%: Carbon 2.5-3.4; silicon 1.0-1.5; manganese 0.2-1.0; magnesium 0.08-0.1; aluminum 1.5-2.5; copper 0.01-0.03; nitrogen 0.01-0.03; 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, магний, алюминий, медь, железо, дополнительно включает молибден и самарий при следующем соотношении компонентов, мас.%: углерод 3,0-3,4; кремний 1,0-1,5; марганец 0,2-0,3; магний 0,005-0,01; алюминий 2,2-2,6; медь 0,6-1,0; молибден 0,6-1,0; самарий 0,3-0,4; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, aluminum, copper, iron, additionally includes molybdenum and samarium in the following ratio of components, wt.%: Carbon 3.0-3.4; silicon 1.0-1.5; manganese 0.2-0.3; magnesium 0.005-0.01; aluminum 2.2-2.6; copper 0.6-1.0; molybdenum 0.6-1.0; samarium 0.3-0.4; 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. Медь и молибден препятствуют возникновению и развитию трещин в чугунных изделиях в условиях перепадов температур. Магний и самарий раскисляют чугун. Алюминий препятствует росту окалины.In the composition of cast iron components manifest themselves as follows. Copper and molybdenum prevent the occurrence and development of cracks in cast iron products under temperature extremes. Magnesium and samarium deoxidize cast iron. Aluminum inhibits the growth of scale.
Чугун выплавляют в электропечах и отливают в обмазанные огнеупорной глиной кокили, предварительно нагретые до температуры 350-450°С. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into chill molds coated with refractory clay, preheated to a temperature of 350-450 ° C. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
