一种羰基镍铁合金粉的制备方法
摘要：
本发明公开了一种羰基镍铁合金粉的制备方法，该方法将CO气体分别通入羰基镍蒸发器和羰基铁蒸发器中，将夹带羰基镍的CO气体和夹带羰基铁的CO气体混合均匀后，通入分解器中进行热分解，其中通入羰基镍蒸发器中的CO气体的温度为50~60℃，通入羰基铁蒸发器中的CO气体的温度为75~90℃。本发明的羰基镍铁合金粉的制备方法能使混合原料气成分稳定性提升，有效维持蒸发器和进料管路工作状态。
摘要（英）：

The invention discloses a preparation method of carbonyl ferronickel alloy powder. The method comprises the following steps: respectively introducing CO gas into a carbonyl nickel evaporator and a carbonyl iron evaporator, uniformly mixing the carbonyl-nickel-entrained CO gas and carbonyl-iron-entrained CO gas, introducing the gas mixture into a decomposer, and carrying out thermal decomposition, wherein the temperature of the CO gas introduced into the carbonyl nickel evaporator is 50-60 DEG C, and the temperature of the CO gas introduced into the carbonyl iron evaporator is 75-90 DEG C. The preparation method can enhance the stability of the mixed raw gas components and effectively maintain the operating state of the evaporators and feed pipeline.
