Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления корпусов шаровых мельниц.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 ball mill housings.
Известен чугун, содержащий, мас.%: углерод 3,5-4,5; кремний 0,1-0,5; марганец 0,01-0,05; фосфор 0,01-0,05; сера 0,005-0,015; бор 0-0,03; хром 0,005-0,04; титан 0,01-0,03; кобальт 0-0,03; селен 0-0,03; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 3,5-4,5; silicon 0.1-0.5; manganese 0.01-0.05; phosphorus 0.01-0.05; sulfur 0.005-0.015; boron 0-0.03; chrome 0.005-0.04; titanium 0.01-0.03; cobalt 0-0.03; selenium 0-0.03; iron - the rest [1].
Задача изобретения состоит в повышении износостойкости чугуна.The objective of the invention is to increase the wear resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, фосфор, серу, бор, хром, титан, кобальт, селен, железо, дополнительно включает литий, теллур, ванадий при следующем соотношении компонентов, мас.%: углерод 3,4-4,0; кремний 0,6-1,0; марганец 0,6-1,0; фосфор 0,06-0,1; сера 0,03-0,05; бор 0,1-0,15; хром 0,1-0,15; титан 0,08-0,12; кобальт 0,3-0,4; селен 0,01-0,02; литий 0,0001-0,0002; теллур 0,0001-0,0002; ванадий 0,2-0,3; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, phosphorus, sulfur, boron, chromium, titanium, cobalt, selenium, iron, additionally includes lithium, tellurium, vanadium in the following ratio of components, wt.%: Carbon 3, 4-4.0; silicon 0.6-1.0; manganese 0.6-1.0; phosphorus 0.06-0.1; sulfur 0.03-0.05; boron 0.1-0.15; chrome 0.1-0.15; titanium 0.08-0.12; cobalt 0.3-0.4; selenium 0.01-0.02; lithium 0.0001-0.0002; tellurium 0.0001-0.0002; vanadium 0.2-0.3; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Карбиды стабилизируются хромом, теллуром и бором. Марганец способствует увеличению твердости. Фосфор образует легкоплавкую эвтектику, состоящую из аустенита и фосфида железа, ее твердые участки повышают износостойкость сплава. Сера и селен препятствуют образованию заусениц. Литий и титан придают структуре сплава мелкозернистость. Ванадий повышает вязкость и пластичность чугуна, кобальт улучшает его структуру.In the composition of cast iron, the components manifest themselves as follows. Carbides are stabilized by chromium, tellurium and boron. Manganese helps increase hardness. Phosphorus forms a low-melting eutectic consisting of austenite and iron phosphide; its hard sections increase the wear resistance of the alloy. Sulfur and selenium prevent the formation of barbs. Lithium and titanium give the alloy structure a fine grain. Vanadium increases the viscosity and ductility of cast iron, cobalt improves its structure.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при 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. The castings are subjected to normalization at 900-950 ° C and tempering at a temperature of 350-450 ° C.
