Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления прокатных валков, валков лакокрасочных и бумагоделательных машин и аналогичных им деталей.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of rolling rolls, rolls of paint and paper machines and similar parts.
Известен чугун следующего состава, мас. %: углерод 2,5-3,2; кремний 0,5-1,5; марганец 0,3-1,1; хром 7,5-11,0; ванадий 0,35-1,5; никель 0,05-1,3; фосфор 0,02-0,1; бор 0,02-0,07; нитриды марганца 0,02-0,18; железо - остальное [1].Known cast iron of the following composition, wt. %: carbon 2.5-3.2; silicon 0.5-1.5; manganese 0.3-1.1; chrome 7.5-11.0; vanadium 0.35-1.5; nickel 0.05-1.3; phosphorus 0.02-0.1; boron 0.02-0.07; manganese nitrides 0.02-0.18; iron - the rest [1].
Задача изобретения состоит в повышении ударной вязкости чугуна.The objective of the invention is to increase the toughness of cast iron.
Технический результат достигается тем, что чугун, включающий углерод, кремний, марганец, хром, ванадий, никель, фосфор, бор, железо, дополнительно содержит алюминий и медь при следующем соотношении компонентов, мас. %: углерод 2,5-3,2; кремний 0,2-0,4; марганец 0,3-0,8; хром 7,5-11,0; ванадий 2,0-3,0; никель 1,5-2,0; фосфор 0,04-0,08; бор 0,02-0,04; алюминий 0,6-1,0; медь 1,0-1,6; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, chromium, vanadium, nickel, phosphorus, boron, iron, additionally contains aluminum and copper in the following ratio of components, wt. %: carbon 2.5-3.2; silicon 0.2-0.4; manganese 0.3-0.8; chrome 7.5-11.0; vanadium 2.0-3.0; nickel 1.5-2.0; phosphorus 0.04-0.08; boron 0.02-0.04; aluminum 0.6-1.0; copper 1.0-1.6; 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. Марганец, фосфор, бор и хром обеспечивают твердость и прочность сплава. Никель улучшает металлическую основу чугуна. Алюминий увеличивает вязкость сплава, раскисляет его. Ванадий и медь повышают прочность чугуна, способствуют увеличению ударной вязкости сплава, препятствуют возникновению и развитию трещин при механических нагрузках.In the composition of cast iron, the components manifest themselves as follows. Manganese, phosphorus, boron and chromium provide hardness and strength of the alloy. Nickel improves the metal base of cast iron. Aluminum increases the viscosity of the alloy, deoxidizes it. Vanadium and copper increase the strength of cast iron, contribute to an increase in the toughness of the alloy, and prevent the occurrence and development of cracks under mechanical loads.
Чугун выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°C.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
