Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого для изготовления деталей двигателей, печей, тепловых агрегатов.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron used for the manufacture of engine parts, furnaces, thermal units.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,5-3,5; марганец 0,2-1,5; магний 0-0,1; алюминий 0-2,0; бор 0-2,0; ниобий 0-2,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.5-3.5; manganese 0.2-1.5; magnesium 0-0.1; aluminum 0-2.0; boron 0-2.0; niobium 0-2.0; 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, магний, алюминий, бор, ниобий, железо, дополнительно содержит кобальт при следующем соотношении компонентов, мас.%: углерод 2,2-2,4; кремний 2,0-3,0; марганец 0,4-0,6; магний 0,01-0,03, алюминий 2,5-3,5; бор 0,1-0,2; ниобий 0,2-0,4, кобальт 1,2-1,6; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, magnesium, aluminum, boron, niobium, iron, additionally contains cobalt in the following ratio of components, wt.%: Carbon 2.2-2.4; silicon 2.0-3.0; manganese 0.4-0.6; magnesium 0.01-0.03, aluminum 2.5-3.5; boron 0.1-0.2; niobium 0.2-0.4, cobalt 1.2-1.6; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Бор стабилизирует карбиды, повышает твердость сплава. Ниобий и кобальт улучшают металлическую основу сплава. Кобальт способствует измельчению зерна. Алюминий повышает вязкость чугуна, препятствует росту окалины. Магний выполняет функцию раскислителя, способствует измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. Boron stabilizes carbides, increases alloy hardness. Niobium and cobalt improve the metal base of the alloy. Cobalt helps grind grain. Aluminum increases the viscosity of cast iron, inhibits the growth of scale. Magnesium acts as a deoxidizer, contributes to the grinding of grain.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
