Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун следующего состава, мас. %: углерод 2,9-3,4; кремний 1,5-2,0; марганец 0,7-1,1; никель 0,2-0,6; хром 0,1-0,3; медь 0,2-0,5; кобальт 0,02-0,1; железо - остальное [1]. Предел прочности данного чугуна составляет 260-295 МПа.Known cast iron of the following composition, wt. %: carbon 2.9-3.4; silicon 1.5-2.0; manganese 0.7-1.1; nickel 0.2-0.6; chrome 0.1-0.3; copper 0.2-0.5; cobalt 0.02-0.1; iron - the rest [1]. The tensile strength of this cast iron is 260-295 MPa.
Задачей изобретения является повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, никель, хром, медь, кобальт, железо, дополнительно содержит рений, бор, алюминий при следующем соотношении компонентов, мас. %: углерод 2,9-3,4; кремний 1,5-2,0; марганец 0,7-1,1; никель 0,8-1,2; хром 0,01-0,03; медь 1,6-1,9; кобальт 0,15-0,25; рений 0,1-0,15; бор 0,054), 1; алюминий 0,05-0,1; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, nickel, chromium, copper, cobalt, iron, additionally contains rhenium, boron, aluminum in the following ratio of components, wt. %: carbon 2.9-3.4; silicon 1.5-2.0; manganese 0.7-1.1; nickel 0.8-1.2; chromium 0.01-0.03; copper 1.6-1.9; cobalt 0.15-0.25; rhenium 0.1-0.15; boron 0.054), 1; aluminum 0.05-0.1; 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, никель, кобальт, рений, бор повышают прочностные характеристики сплава. Медь, кобальт, никель препятствуют образованию и развитию трещин в чугунных изделиях. Хром и бор стабилизируют карбиды. Алюминий раскисляет сплав.In the composition of cast iron, the components manifest themselves as follows. Copper, nickel, cobalt, rhenium, boron increase the strength characteristics of the alloy. Copper, cobalt, nickel prevent the formation and development of cracks in cast iron products. Chrome and boron stabilize carbides. Aluminum deoxidizes the alloy.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°С.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
