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, содержащий, мас.%: углерод 1,5-4,0; кремний 0-1,5; марганец 0,05-1,5; хром 0,02-1,5; ванадий не более 3,0; никель не более 2,0; алюминий 0,05-2,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.5-4.0; silicon 0-1.5; manganese 0.05-1.5; chrome 0.02-1.5; vanadium not more than 3.0; nickel no more than 2.0; aluminum 0.05-2.0; iron - the rest [1].
Задача изобретения - повышение трещиноустойчивости чугуна.The objective of the invention is to increase the crack resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, ванадий, никель, алюминий, железо, дополнительно содержит цирконий и барий при следующем соотношении компонентов, мас.%: углерод 2,2-2,6; кремний 0,05-0,1; марганец 0,1-0,2; хром 0,5-0,9; ванадий 2,1-2,5; никель 0,8-1,2; алюминий 2,1-2,18; цирконий 0,2-0,4; барий 0,007-0,009; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, vanadium, nickel, aluminum, iron, additionally contains zirconium and barium in the following ratio of components, wt.%: Carbon 2.2-2.6; silicon 0.05-0.1; manganese 0.1-0.2; chrome 0.5-0.9; vanadium 2.1-2.5; nickel 0.8-1.2; aluminum 2.1-2.18; zirconium 0.2-0.4; barium 0.007-0.009; iron is the rest.
Повышение трещиноустойчивости чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Никель снижает устойчивость первичных карбидов, улучшает металлическую основу сплава путем увеличения количества и упрочнения феррита в перлите. Хром стабилизирует карбиды, упрочняет твердый раствор. Алюминий повышает вязкость. Ванадий и барий выполняют функцию раскислителей. Цирконий придает структуре чугуна мелкозернистость.The increase in crack resistance of cast iron is achieved due to the complex effect of the components included in its composition. Nickel reduces the stability of primary carbides, improves the metal base of the alloy by increasing the amount and hardening of ferrite in perlite. Chromium stabilizes carbides, strengthens a solid solution. Aluminum increases viscosity. Vanadium and barium act as deoxidants. Zirconium gives the structure of cast iron fine grain.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Работа образования трещин в чугуне составит 1,5-1,55 кДж для всех приведенных в таблице составов.The cracking work in cast iron will be 1.5-1.55 kJ for all the compositions listed in the table.
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.
