Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, который может найти применение в изготовлении прокатных валков, тормозных колодок, дисков сцепления и других деталей, работающих в условиях трения и повышенного износаThe invention relates to the field of metallurgy and relates to compositions of cast iron, which can be used in the manufacture of rolling rolls, brake pads, clutch discs and other parts operating under friction and increased wear
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; никель 0-2,5; хром 0-1,5; бор 0-1,0; цирконий 0-1,0; ванадий 0-1,0; кальций 0-0,2; молибден 0-0,8; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; copper 0-4.0; nickel 0-2.5; chrome 0-1.5; boron 0-1.0; zirconium 0-1.0; vanadium 0-1.0; calcium 0-0.2; molybdenum 0-0.8; iron - the rest [1].
Задача изобретения состоит в повышении износостойкости чугунаThe objective of the invention is to increase the wear resistance of cast iron
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, медь, никель, хром, бор, цирконий, ванадий, кальций, молибден, железо, дополнительно включает магний, церий и азот при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 1,0-1,5; марганец 1,0-1,5; медь 0,5-1,0; никель 1,0-1,5; хром 0,5-1,0, бор 0,05-0,1; цирконий 0,1-0,2; ванадий 0,1-0,2; кальций 0,005-0,01; молибден 1,0-1,5; магний 0,005-0,01; церий 0,05-0,1; азот 0,05-0,1; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, nickel, chromium, boron, zirconium, vanadium, calcium, molybdenum, iron, additionally includes magnesium, cerium and nitrogen in the following ratio of components, wt.%: Carbon 3.0-3.5; silicon 1.0-1.5; manganese 1.0-1.5; copper 0.5-1.0; nickel 1.0-1.5; chrome 0.5-1.0, boron 0.05-0.1; zirconium 0.1-0.2; vanadium 0.1-0.2; calcium 0.005-0.01; molybdenum 1.0-1.5; magnesium 0.005-0.01; cerium 0.05-0.1; nitrogen 0.05-0.1; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение износостойкости чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Хром обеспечивает повышенную твердость сплава. Бор стабилизирует карбиды. В химически связанном состоянии с ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства чугуна. Молибден упрочняет твердый раствор. Медь и никель способствуют графитизации, улучшают металлическую основу сплава. Магний, церий и кальций раскисляют чугун, способствуют образованию мелкозернистой структуры.The increase in wear resistance of cast iron is due to the complex effect of the components that make up its composition. Chrome provides increased alloy hardness. Boron stabilizes carbides. In a chemically bound state with vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of cast iron. Molybdenum strengthens the solid solution. Copper and nickel contribute to graphitization, improve the metal base of the alloy. Magnesium, cerium and calcium deoxidize cast iron, contribute to the formation of a fine-grained structure.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
