Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в машиностроении, судостроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in mechanical engineering, shipbuilding.
Известен чугун следующего состава, мас.%: углерод 2,0-4,0; кремний 3,8-4,5; марганец <1,0; хром 3,0-15,0; ниобий 0,01-0,1; титан <0,1; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 2.0-4.0; silicon 3.8-4.5; manganese <1.0; chrome 3.0-15.0; niobium 0.01-0.1; titanium <0.1; iron - the rest [1].
Задача изобретения состоит в повышении коррозионной стойкости чугуна.The objective of the invention is to increase the corrosion resistance of cast iron.
Технический результат достигается тем, что чугун, включающий углерод, кремний, марганец, хром, ниобий, железо, дополнительно содержит бор, селен, цирконий, теллур при следующем соотношении компонентов, мас.%: углерод 1,9-2,3; кремний 4,1-4,5; марганец 0,9-1,5; хром 3,0-3,8; ниобий 0,2-0,4; бор 0,1-0,16; селен 0,002-0,004; цирконий 0,2-0,4; теллур 0,002-0,004; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, chromium, niobium, iron, additionally contains boron, selenium, zirconium, tellurium in the following ratio of components, wt.%: Carbon 1.9-2.3; silicon 4.1-4.5; Manganese 0.9-1.5; chrome 3.0-3.8; niobium 0.2-0.4; boron 0.1-0.16; selenium 0.002-0.004; zirconium 0.2-0.4; tellurium 0.002-0.004; 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. Хром, бор и марганец повышают твердость чугуна. Хром, ниобий обеспечивают коррозионную стойкость сплава. Цирконий и селен замедляют процессы коррозии сплава. Бор и теллур стабилизируют карбиды. Ниобий улучшает металлическую основу чугуна.In the composition of cast iron, the components manifest themselves as follows. Chrome, boron and manganese increase the hardness of cast iron. Chrome, niobium provide corrosion resistance of the alloy. Zirconium and selenium slow down alloy corrosion processes. Boron and tellurium stabilize carbides. Niobium improves the metal base of cast iron.
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.
