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 мышьяк, селен, цирконий, никель, 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; мышьяк 0,0001-0,0002; селен 0,002-0,004; цирконий 0,2-0,4; никель 1,0-1,4; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, chromium, niobium, iron, additionally contains arsenic, selenium, zirconium, nickel, 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; arsenic 0.0001-0.0002; selenium 0.002-0.004; zirconium 0.2-0.4; nickel 1.0-1.4; 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 и марганец повышают твердость чугуна. Хром, ниобий обеспечивают коррозионную стойкость сплава. Цирконий, мышьяк и селен замедляют процессы коррозии сплава. Мышьяк и селен незначительно снижают прочность чугуна. Ниобий и никель улучшают металлическую основу чугуна.In the composition of cast iron, the components manifest themselves as follows. Chrome and manganese increase the hardness of cast iron. Chrome, niobium provide corrosion resistance of the alloy. Zirconium, arsenic and selenium slow down the corrosion of the alloy. Arsenic and selenium slightly reduce the strength of cast iron. Niobium and nickel improve the metal base of cast iron.
Чугун выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.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.
