Abstract
Description
Изобретение относится к области металлургии и касается составов чугуна, который может найти применение в производстве конфорок газовых и электроплит.The invention relates to the field of metallurgy and relates to compositions of cast iron, which may find application in the production of gas burners and electric stoves.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; алюминий 0-0,2; месть 0-4,0; никель 0-2,5; РЗМ 0-0,2; цирконий 0-1,0; молибден 0-0,8; ниобий 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; aluminum 0-0.2; revenge 0-4.0; nickel 0-2.5; REM 0-0.2; zirconium 0-1.0; molybdenum 0-0.8; niobium 0-1.0; iron - the rest [1].
Задача изобретения состоит в повышении термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, медь, никель, РЗМ, цирконий, молибден, ниобий, железо, дополнительно включает магний, при следующем соотношении компонентов, мас.%: углерод 2,5-3,0; кремний 0,7-1,3; марганец 0,5-1,0; алюминий 2,7-3,2; медь 0,15-0,3; никель 0,3-0,5; РЗМ 0,03-0,07; цирконий 0,07-0,15; молибден 0,3-0,5; ниобий 0,05-0,1; магний 0,03-0,07; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, copper, nickel, rare-earth metals, zirconium, molybdenum, niobium, iron, additionally includes magnesium, in the following ratio, wt.%: Carbon 2.5-3 0; silicon 0.7-1.3; manganese 0.5-1.0; aluminum 2.7-3.2; copper 0.15-0.3; nickel 0.3-0.5; REM 0.03-0.07; zirconium 0.07-0.15; molybdenum 0.3-0.5; niobium 0.05-0.1; magnesium 0.03-0.07; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Термостойкость чугуна составит (нагрев до 650°С - охлаждение в воде до 20°С): для 1-го и 2-го составов - 125-127 циклов, для 3-го составов - 123-125 циклов.The heat resistance of cast iron will be (heating to 650 ° C - cooling in water to 20 ° C): for the 1st and 2nd compounds - 125-127 cycles, for the 3rd composition - 123-125 cycles.
Присутствующие в составе чугуна, компоненты: проявляют себя следующим образом. Ниобий и молибден упрочняют твердый раствор. Никель улучшает структуру чугуна. Медь способствует графитизации и резко увеличивает содержание в сплаве перлита. Марганец способствует измельчению перлит. Алюминий препятствует росту окалины. Магний и РЗМ выполняют функцию раскислителей. Цирконий придает мелкозернистость структуре сплава.Components present in the composition of cast iron: manifest themselves as follows. Niobium and molybdenum strengthen the solid solution. Nickel improves the structure of cast iron. Copper promotes graphitization and dramatically increases the content of perlite in the alloy. Manganese contributes to the grinding of perlite. Aluminum inhibits the growth of scale. Magnesium and REM perform the function of deoxidizers. Zirconium gives a fine grain structure to the alloy.
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.
