Abstract
Description
Изобретение относится к области металлургии, в частности к составам серого чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular to compositions of gray cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,4-0,8; алюминий 0,1-0,2; медь 1,6-2,0; ванадий 1,0-1,6; гафний 0,3-0,7; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3.0-3.4; silicon 0.8-1.2; manganese 0.4-0.8; aluminum 0.1-0.2; copper 1.6-2.0; vanadium 1.0-1.6; hafnium 0.3-0.7; iron - the rest [1].
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, алюминий, медь, ванадий, гафний, железо, дополнительно включает никель, бор и кальций, причем компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,4; кремний 0,8-1,2; марганец 0,4-0,8; алюминий 0,03-0,05; медь 0,9-1,3; ванадий 0,6-0,8; гафний 0,1-0,2; никель 0,7-1,3; бор 0,03-0,05; кальций 0,0003-0,0005; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, vanadium, hafnium, iron, additionally includes nickel, boron and calcium, and the components are in the following ratio, wt.%: Carbon 3.0-3 ,four; silicon 0.8-1.2; manganese 0.4-0.8; aluminum 0.03-0.05; copper 0.9-1.3; vanadium 0.6-0.8; hafnium 0.1-0.2; nickel 0.7-1.3; boron 0.03-0.05; calcium 0.0003-0.0005; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Прочность чугуна при растяжении составит ~ 900 МПа для всх приведенных в таблице составов.The tensile strength of cast iron will be ~ 900 MPa for all the compositions listed in the table.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Ванадий, медь, никель, гафний повышают вязкость и прочность сплава. Алюминий и кальций раскисляют сплав. Бор стабилизирует карбиды.The increase in cast iron strength is due to the complex effect of the components that make up its composition. Vanadium, copper, nickel, hafnium increase the viscosity and strength of the alloy. Aluminum and calcium deoxidize the alloy. Boron stabilizes carbides.
Чугун выплавляют в электропечах и отливают в горячие (400-500°C) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отпуску при температуре 550-650°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 tempering at a temperature of 550-650 ° C.
