Furnace burden and device for direct reduction of coal group

The utility model relates to a furnace burden used for the iron-making of the coal based reduction method and a device. The furnace burden used for the iron-making of the coal based reduction method is characterized in that: the pellet or the lump or the briquette is wrapped externally with shielding wrapping protection layer which is made of nonmagnetic high temperature resistant material. The shielding material adding unit for the iron-making of the coal based reduction method is characterized in that: the device comprises an impeller feeder and a ring-shaped feeder; the impeller feeder comprises a receiving cone, a feeder body, an impeller shaft, an operation wheel and a pipe chute. The utility model has the advantages of realizing normal operation and stable production under high temperature, overcoming the problems such as low furnace temperature for the prior art, bonding iron ore powder for the inner wall of the reduction furnace and causing nodulation and ringing, increasing output and improving production efficiency.
