Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован в автомобилестроении.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used in the automotive industry.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; хром 0,01-2,0; молибден 0,01-2,0; медь ≤0,2; бериллий 0,01-0,2; бор 0,01-0,1; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; chromium 0.01-2.0; molybdenum 0.01-2.0; copper ≤0.2; beryllium 0.01-0.2; boron 0.01-0.1; 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, хром, молибден, медь, бериллий, бор, железо, дополнительно содержит кальций и церий при следующем соотношении компонентов, мас.%: углерод 3,6-3,8; кремний 1,6-2,0; марганец 0,6-0,8; хром 0,45-0,65; молибден 1,6-2,0; медь 1,0-1,4; бериллий 0,003-0,005; бор 0,12-0,16; кальций 0,003-0,007; церий 0,22-0,28; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, molybdenum, copper, beryllium, boron, iron, additionally contains calcium and cerium in the following ratio of components, wt.%: Carbon 3,6-3,8; silicon 1.6-2.0; manganese 0.6-0.8; chromium 0.45-0.65; molybdenum 1.6-2.0; copper 1.0-1.4; beryllium 0.003-0.005; boron 0.12-0.16; calcium 0.003-0.007; cerium 0.22-0.28; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение прочности чугуна обусловлено комплексным влиянием компонентов, входящих в его состав. Присутствие меди усиливает графитизацию и увеличивает содержание перлита. Марганец тормозит выделение графита, способствует измельчению перлита. Молибден повышает прочностные характеристики чугуна, увеличивает твердость, делает его теплоустойчивым, увеличивает несущую способность конструкций при ударных нагрузках. Хром и бор стабилизируют карбиды. Церий и кальций раскисляют сплав. Церий нейтрализует вредное влияние примесей серы. Бериллий обеспечивает мелкозернистость структуры чугуна.The increase in the strength of cast iron is due to the complex effect of the components that make up its composition. The presence of copper enhances graphitization and increases the content of perlite. Manganese inhibits the release of graphite, contributes to the grinding of perlite. Molybdenum increases the strength characteristics of cast iron, increases hardness, makes it heat-resistant, increases the bearing capacity of structures under shock loads. Chrome and boron stabilize carbides. Cerium and calcium deoxidize the alloy. Cerium neutralizes the harmful effects of sulfur impurities. Beryllium provides a fine-grained structure of cast iron.
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.
