Abstract：
 A process for preparing Fe alloy powder by reducing the iron ore concentrate and the iron and steel scales generated by rolling includes charging reducing agent (coke and lime stone), said iron and steel scales, iron ore concentrate, coke and calcium carbonate into refractory pot, drying, heating to 1000-1200 deg.C, maintaining the temp, cooling, and secondary reduction by introducing hydrogen gas. The resultant has better alloy strengthening action on iron powder.
