Изобретение относитс к производству железных норошковИзвестен , способ получени железного порошка восстановлением окислов железа сажей , например, марки ТГМ-33, в присутствии активирующих добавок.This invention relates to the production of iron holes. A method for producing iron powder is known by reducing iron oxides with carbon black, for example, TGM-33, in the presence of adjuvants.
Дл упроидени технологии процесса и повышени степени чистоты порошков, в качестве восстановител используют сажу, полученную в результате окислительного пиролиза природного газа до ацетилена.To streamline the process technology and increase the purity of the powders, carbon black obtained as a result of the oxidative pyrolysis of natural gas to acetylene is used as a reducing agent.
Пиролизна сажа обладает высокой восстановительной способностью. Ее можно использовать нри восстановлении окислов железа непосредственно в твердой фазе или комбинированном восстановлении, т. е. с участием газового восстановител . В нервом случа при температуре восстаповлени 1000°С восстановитатьна способность пиролизной сажи в 5 раз больше, чем у сажи марки ТГМ33 . во втором случае - в 2,5 раз.Pyrolysis soot has a high reducing ability. It can be used in the reduction of iron oxides directly in the solid phase or combined reduction, i.e. with the participation of a gas reducing agent. In a nerve case, at a recovery temperature of 1000 ° C, the capacity of pyrolysis carbon black is 5 times higher than that of TGM33 soot. in the second case - 2.5 times.
Данный способ не требует применени активирующих добавок, что позвол ет повысить степень чистоты готового продукта.This method does not require the use of adjuvants, which improves the purity of the finished product.
