Rare alloy powder continuous dehydrogenation electric furnace and treatment process

The rare alloy powder continuous dehydrogenation electric furnace comprises a furnace body, a box body is fixed to one side of the furnace body, a sieve plate is connected between the inner walls of the furnace body in a sliding mode, and a rotary uniform spreading mechanism used for spreading alloy powder on the top of the sieve plate is arranged above the sieve plate; and the rotating type uniform spreading mechanism comprises two fixing plates fixed to the inner wall of the furnace body, and an annular plate is fixed between the opposite sides of the two fixing plates. According to the rare alloy powder continuous dehydrogenation electric furnace and the treatment process, through the arrangement of the rotary uniform spreading mechanism, the alloy powder on the top of the sieve plate is automatically and uniformly spread through the rotation of three groups of spreading plates and the revolution motion around the pinion, the alloy powder is prevented from being accumulated on the top of the sieve plate, a
