Technique for preparing nickel-iron alloy

The invention belongs to the field of metallurgical technology, and more particularly relates to a technique for preparing nickel-iron alloy. The technique aims at solving the technical problem of providing the technique which is used for preparing nickel-iron alloy, has high production efficiency, short process flow and low energy consumption, takes common coal as reducing agent and ensures burden not to be easily agglomerated. The technical scheme comprises the steps: A. after mixing nickel oxide-containing raw material, pulverized coal and fusing agent, pelletizing the mixture; B. reducingpellets and obtaining metalized pellets; C. smelting the metalized pellets and obtaining crude nickel-iron alloy; D refining the nickel-iron alloy and obtaining refined nickel-iron alloy. The technique has the raw material which is internally provided with pulverized coal pellets, enlarges the reaction area, improves the dynamical condition and is beneficial to the reduction process. Furthermore,the technique has the adva
