Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован в машиностроении.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering.
Известен чугун, содержащий, мас.%: углерод 2,7-3,1; кремний 2,2-2,6; марганец 0,2-0,7; олово 0,002-0,01; хром 0,02-0,06; ванадий 0,2-0,8; сурьма 0,02-0,06; алюминий 0,02-0,07; медь 0,8-1,6; азот 0,04-0,11; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.7-3.1; silicon 2.2-2.6; manganese 0.2-0.7; tin 0.002-0.01; chrome 0.02-0.06; vanadium 0.2-0.8; antimony 0.02-0.06; aluminum 0.02-0.07; copper 0.8-1.6; nitrogen 0.04-0.11; iron - the rest [1].
Задачей изобретения является повышение литейных свойств чугуна.The objective of the invention is to improve the casting properties of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, олово, хром, ванадий, сурьму, алюминий, медь, азот, железо, дополнительно включает церий и бор, причем компоненты находятся при следующем соотношении, мас.%: углерод 2,7-3,1; кремний 2,2-2,6; марганец 0,1-0,15; олово 0,012-0,015; хром 0,02-0,06; ванадий 1,0-1,4; сурьма 0,02-0,06; алюминий 0,2-0,3; медь 0,3-0,5; азот 0,01-0,02; церий 0,03-0,08; бор 0,03-0,08; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, tin, chromium, vanadium, antimony, aluminum, copper, nitrogen, iron, additionally includes cerium and boron, and the components are in the following ratio, wt.%: Carbon 2 7-3.1; silicon 2.2-2.6; manganese 0.1-0.15; tin 0.012-0.015; chrome 0.02-0.06; vanadium 1.0-1.4; antimony 0.02-0.06; aluminum 0.2-0.3; copper 0.3-0.5; nitrogen 0.01-0.02; cerium 0.03-0.08; boron 0.03-0.08; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение литейных свойств чугуна достигается за счет комплексного влияния входящих в его состав компонентов. Медь способствует равномерному охлаждению отливок. Хром и бор стабилизируют карбиды. Бор повышает жидкотекучесть сплава. В химически связанном состоянии с алюминием и ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и литейные свойства чугуна. Церий, олово и сурьма уменьшают объем усадочной раковины. Церий раскисляет сплав, способствует измельчению зерна.Improving the casting properties of cast iron is achieved due to the complex effect of its constituent components. Copper promotes uniform cooling of castings. Chrome and boron stabilize carbides. Boron increases the fluidity of the alloy. In a chemically bound state with aluminum and vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and casting properties of cast iron. Cerium, tin and antimony reduce the volume of the shrink shell. Cerium deoxidizes the alloy, contributes to the grinding of grain.
Чугун выплавляют в электропечах и отливают в формы. 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 molds. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
