Description
Известны способы восстановлени окислов железа нагреванием их в присутствии углерода и использование сажи в качестве углеродистого восстановител . Известно применение в промышленности трубчатых печей дл осуществлени восстановительных процессов.Methods are known for reducing iron oxides by heating them in the presence of carbon and using carbon black as a carbonaceous reducing agent. It is known to use industry in tube furnaces for carrying out reduction processes.
Предлагаемый способ приготовлени исходной массы дл изготовлени отрицательного электрода щелочных железоникелевых аккумул торов из криворожской руды «Синька, заключаетс в восстановлении ее сажей в вращающихс трубчатых печах при 900-950 или в стационарных трубчатых печах при 680-700°.The proposed method of preparing the initial mass for the manufacture of the negative electrode of alkaline iron-nickel batteries from Krivoy Rog Blueka ore consists in restoring it with soot in rotating tube furnaces at 900-950 or in stationary tube furnaces at 680-700.
При восстановлении руды «Синька и других мартитогематитовых руд ламповой сажей, последн беретс в дозировке 2%, в то врем как при ранее примен вщемс способе восстановлени руд электролитическим железным порощком, его требовалось 10-12%. Применение вращающихс трубчатых печей дл осуществлени данного, процесса ювышает его производительность в несколько раз. Этим достигают снижени себестоимости целевого продукта и повыщают его качество. Из приведенных в таблицах данных видно, что руда, восстановленна ламповой сажей, имеет электрические характеристики на 15-20% выще , чем руда, восстановленна электролитическим железным порощком. Лампова сажа, как восстановитель, в 4 раза дещевле электролитического железного порощка; в количественном отнощении сажи беретс в 5-6 раз меньше, чем электролитического железного порошка.When ores were reduced, Blueka and other margotite-hematite ores of lamp soot were taken in a dosage of 2%, while in the previously used ore reduction method with an electrolytic iron powder, it was required 10-12%. The use of rotary tube furnaces to accomplish this process increases its productivity several times. This achieves a reduction in the cost of the target product and increases its quality. From the data in the tables it can be seen that the ore recovered by the lamp soot has electrical characteristics 15-20% higher than the ore recovered by an electrolytic iron powder. Lamp soot, as a reducing agent, is 4 times less expensive than an electrolytic iron powder; in terms of soot, it is 5-6 times less than electrolytic iron powder.
Сравнительные данные по восстановлению руды «Синька электролитическим порощком и ламповой сажей показаны в таблицах 1 и 2.Comparative data on the recovery of ore "Blueka electrolytic powder and lamp soot are shown in Tables 1 and 2.
