Abstract
Description
Изобретение относится к области металлургии и касается составов серого чугуна, который может быть использован в общем машиностроении.The invention relates to the field of metallurgy and relates to compositions of gray cast iron, which can be used in general engineering.
Известен чугун, содержащий, мас.%: углерод 2,8-3,2; кремний 1,75-2,5; марганец 0,3-0,8; магний 0,03-0,08; медь 0,6-1,5; церий 0,03-0,08; бор 0,008-0,02; ниобий 0,03-0,1; азот 6,03-0,1; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.8-3.2; silicon 1.75-2.5; manganese 0.3-0.8; magnesium 0.03-0.08; copper 0.6-1.5; cerium 0.03-0.08; boron 0.008-0.02; niobium 0.03-0.1; nitrogen 6.03-0.1; iron - the rest [1].
Задача изобретения состоит в повышении 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, магний, медь, церий, бор, ниобий, азот, железо, дополнительно содержит молибден и кобальт, при следующем соотношении компонентов, мас.%: углерод 2,8-3,2; кремний 1,2-1,6; марганец 0,5-1,0; магний 0,01-0,03; медь 0,5-1,0; церий 0,05-0,1, бор 0,03-0,08, ниобий 0,3-0,5; азот 0,05-0,1, молибден 3,0-4,0; кобальт 0,8-1,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, copper, cerium, boron, niobium, nitrogen, iron, additionally contains molybdenum and cobalt, with the following ratio of components, wt.%: Carbon 2.8-3 , 2; silicon 1.2-1.6; manganese 0.5-1.0; magnesium 0.01-0.03; copper 0.5-1.0; cerium 0.05-0.1, boron 0.03-0.08, niobium 0.3-0.5; nitrogen 0.05-0.1, molybdenum 3.0-4.0; cobalt 0.8-1.2; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Никель снижает устойчивость первичных карбидов, улучшает металлическую основу сплава путем увеличения количества перлита и упрочнения феррита в перлите. Медь также способствует графитизации и увеличивает содержание в сплаве перлита. Бор стабилизирует карбиды. Ниобий, молибден и кобальт упрочняют твердый раствор. В химически связанном состоянии азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства сплава. Магний и церий выполняют функцию раскислителей.In the composition of cast iron, the components manifest themselves as follows. Nickel reduces the stability of primary carbides, improves the metal base of the alloy by increasing the amount of perlite and hardening ferrite in perlite. Copper also promotes graphitization and increases the content of perlite in the alloy. Boron stabilizes carbides. Niobium, molybdenum and cobalt strengthen the solid solution. In a chemically bound state, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of the alloy. Magnesium and cerium act as deoxidizers.
Чугун выплавляют в электропечах и отливают в формы. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Отливки подвергают нормализации при температуре 900-950°С и отпуску при температуре 350-450°C.Cast iron is smelted in electric furnaces and cast into molds. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. Castings are subjected to normalization at a temperature of 900-950 ° C and tempering at a temperature of 350-450 ° C.
