Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в станкостроении, машиностроении для легкой промышленности.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in machine tools, mechanical engineering for light industry.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; алюминий 0-0,2; кальций 0-0,2; фосфор 0,05-1,5; ванадий 0-1,0; бор 0-1,0; 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; aluminum 0-0.2; calcium 0-0.2; phosphorus 0.05-1.5; vanadium 0-1.0; boron 0-1.0; 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 в чугуне, содержащем углерод, кремний, марганец, фосфор, кальций, титан, бор, медь, молибден, ванадий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,5; кремний 1,0-1,5; марганец 0,5-1,0; фосфор 0,1-0,2; кальций 0,002-0,004; титан 0,1-0,2; бор 0,005-0,01; медь 0,8-1,2; молибден 4,8-5,2; ванадий 1,2-2,2; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, phosphorus, calcium, titanium, boron, copper, molybdenum, vanadium, iron, the components are in the following ratio, wt.%: Carbon 3.0-3.5 ; silicon 1.0-1.5; manganese 0.5-1.0; phosphorus 0.1-0.2; calcium 0.002-0.004; titanium 0.1-0.2; boron 0.005-0.01; copper 0.8-1.2; molybdenum 4.8-5.2; vanadium 1.2-2.2; iron is the rest.
В таблице приведены составы чугуна. Для всех приведенных в таблице составов предел прочности чугуна при растяжении 850-900 МПа.The table shows the composition of cast iron. For all the compositions listed in the table, the tensile strength of cast iron is 850–900 MPa.
Повышение прочности чугуна обусловлено влиянием компонентов, входящих в его состав. Медь способствует графитизации и резко увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлита. Молибден в сочетании с ванадием упрочняет твердый раствор, улучшает металлическую основу перлитного чугуна. Кальций выполняет функцию раскислителя. Бор стабилизирует карбиды. Титан образует карбонитриды титана, которые способствуют повышению механических свойств чугуна и придают мелкозернистость его структуре. Фосфор, образуя легкоплавкую эвтектику, состоящую из аустенита и фосфида железа (Fe3Р), обеспечивает качество отливок.The increase in the strength of cast iron is due to the influence of the components that make up its composition. Copper promotes graphitization and dramatically increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Molybdenum in combination with vanadium strengthens the solid solution, improves the metal base of pearlite cast iron. Calcium acts as a deoxidizer. Boron stabilizes carbides. Titanium forms titanium carbonitrides, which contribute to the increase in the mechanical properties of cast iron and give a fine-grained structure. Phosphorus, forming a low-melting eutectic, consisting of austenite and iron phosphide (Fe 3 P), ensures the quality of castings.
Чугун выплавляют в электропечах и отливают центробежным способом в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают нормализации при температуре 900-950°C и отпуску гари температуре 350-450°C.Cast iron is smelted in electric furnaces and centrifugally cast in hot (400-500 ° C) metal molds coated with refractory clay. Castings are subjected to normalization at a temperature of 900–950 ° C and tempering of a burning temperature of 350–450 ° C.
