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 в чугуне, содержащем углерод, марганец, хром, ванадий, никель, алюминий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,14-2,26; марганец 0,01-0,05; хром 0,01-0,05; ванадий 3,3-3,9; никель 3,3-3,9; алюминий 3,3-3,9; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, manganese, chromium, vanadium, nickel, aluminum, iron, the components are in the following ratio, wt.%: Carbon 2.14-2.26; manganese 0.01-0.05; chromium 0.01-0.05; vanadium 3.3-3.9; nickel 3.3-3.9; aluminum 3.3-3.9; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Работа образования трещин в чугуне составит ~1,5 кДж для всех приведенных в таблице составов.The cracking work in cast iron will be ~ 1.5 kJ for all the compositions listed in the table.
Повышение трещиноустойчивости чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Никель снижает устойчивость первичных карбидов, улучшает металлическую основу сплава. Ванадий и алюминий повышают вязкость сплава. Хром и марганец стабилизируют карбиды.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. Vanadium and aluminum increase the viscosity of the alloy. Chrome and manganese stabilize carbides.
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.
