Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быть использован для изготовления прокатных валков.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of rolling rolls.
Известен чугун, содержащий, мас.%: углерод 2,5-6,5; кремний 0,8-2,5; марганец 0,4-1,5; хром 16,0-35,0; молибден 0-3,5; ванадий 0,1-2,0, никель 0-2,0, медь 0-1,0; ниобий 0-1,5; титан 0-0,8; алюминий 0-0,1; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-6.5; silicon 0.8-2.5; manganese 0.4-1.5; chrome 16.0-35.0; molybdenum 0-3.5; vanadium 0.1-2.0, nickel 0-2.0, copper 0-1.0; niobium 0-1.5; titanium 0-0.8; aluminum 0-0.1; iron - the rest [1].
Задача изобретения состоит в повышении сопротивления чугуна термической усталости.The objective of the invention is to increase the resistance of cast iron to thermal fatigue.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, хром, молибден, ванадий, никель, медь, ниобий, титан, алюминий, железо, дополнительно включает магний и бор при следующем соотношении компонентов, мас.%: углерод 2,2-2,6; кремний 0,4-0,8; марганец 0,8-1,2; хром 22,0-26,0, молибден 0,8-1,2; ванадий 1,8-2,2; никель 1,8-2,2; медь 0,8-1,2; ниобий 0,8-1,2; титан 0,2-0,4; алюминий 0,2-0,4; магний 0,004-0,006; бор 0,04-0,06; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, molybdenum, vanadium, nickel, copper, niobium, titanium, aluminum, iron, additionally includes magnesium and boron in the following ratio of components, wt.%: Carbon 2, 2-2.6; silicon 0.4-0.8; manganese 0.8-1.2; chromium 22.0-26.0, molybdenum 0.8-1.2; vanadium 1.8-2.2; nickel 1.8-2.2; copper 0.8-1.2; niobium 0.8-1.2; titanium 0.2-0.4; aluminum 0.2-0.4; magnesium 0.004-0.006; boron 0.04-0.06; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Сопротивление чугуна термической усталости (нагрев образцов размера 50×70×10 мм до 900°С - охлаждение в воде до образования видимой сетки трещин) составит 35-40 циклов для всех приведенных в таблице составов.The resistance of thermal fatigue iron (heating samples of size 50 × 70 × 10 mm to 900 ° C — cooling in water until a visible network of cracks forms) will be 35–40 cycles for all the compositions listed in the table.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Хром обеспечивает повышенную твердость чугуна, препятствует росту окалины. Никель и медь увеличивают пластические свойства сплава. Ванадий, молибден и ниобий упрочняют твердый раствор. Бор, титан, алюминий, магний способствуют измельчению зерна, препятствуют образованию трещин.The components present in the composition of cast iron manifest themselves as follows. Chromium provides increased hardness of cast iron, prevents the growth of scale. Nickel and copper increase the plastic properties of the alloy. Vanadium, molybdenum and niobium strengthen the solid solution. Boron, titanium, aluminum, magnesium contribute to the grinding of grain, prevent the formation of cracks.
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.
