Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован, например, для изготовления конфорок электроплит.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used, for example, for the manufacture of hotplates.
Известен чугун следующего состава, мас. %: углерод 3,2-3,7; кремний 2,4-3,2; марганец 0,2-0,6; алюминий 0,01-0,2; кальций 0,001-0,01; титан 0,5-0,7; олово 0,001-0,01; железо - остальное [1].Known cast iron of the following composition, wt. %: carbon 3.2-3.7; silicon 2.4-3.2; manganese 0.2-0.6; aluminum 0.01-0.2; calcium 0.001-0.01; titanium 0.5-0.7; tin 0.001-0.01; iron - the rest [1].
Задачей изобретения является повышение 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, кальций, олово, железо, дополнительно содержит кобальт, вольфрам и ванадий при следующем соотношении компонентов, мас. %: углерод 4,2-4,6; кремний 2,4-3,2; марганец 0,8-1,2; алюминий 2,7-3,0; кальций 0,005-0,01; олово 0,001-0,01; кобальт 6,0-6,5; вольфрам 0,3-0,4; ванадий 0,4-0,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, calcium, tin, iron, additionally contains cobalt, tungsten and vanadium in the following ratio of components, wt. %: carbon 4.2-4.6; silicon 2.4-3.2; manganese 0.8-1.2; aluminum 2.7-3.0; calcium 0.005-0.01; tin 0.001-0.01; cobalt 6.0-6.5; tungsten 0.3-0.4; vanadium 0.4-0.6; iron is the rest.
В таблице приведены составы чугуна. 
Алюминий, кальций, ванадий, кобальт, вольфрам повышают термостойкость чугуна. Алюминий способствует равномерному прогреву и охлаждению чугуна. Ванадий, вольфрам и алюминий препятствуют образованию и развитию трещин в чугунных изделиях при резких перепадах температур.Aluminum, calcium, vanadium, cobalt, tungsten increase the heat resistance of cast iron. Aluminum contributes to uniform heating and cooling of cast iron. Vanadium, tungsten and aluminum prevent the formation and development of cracks in cast iron products at sudden changes in temperature.
Чугун выплавляют в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 600°С.Cast iron is smelted in electric furnaces and cast into hot (400-500 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 600 ° C.
