The invention belongs to the technical field of ferrous metallurgy, and relates to a method for conveying thermal-state rotary furnace metallized pellets in the anharmonic vibration mode. The invention is characterized in that metallized pellets from a spiral discharging machine of the rotary furnace go into a buffer bin through a charging chute; nitrogen gas or other inert gases are introduced into the buffer bin to isolate the air; the metallized pellets go into a continuous anharmonic vibration device from a discharging chute through the outlet of the buffer bin, and the anharmonic vibration device conveys the thermal-state rotary furnace metallized pellets; the metallized pellets are conveyed forward stepwise and are sent into an arc furnace through a feeding passage; and the invention is applicable to steel mills which annually produce 100-1000 thousand tons of rotary furnace metallized pellets and 100-2000 thousand tons of steel, wherein the ratio of the added metallized pelletsto the steel is 1-100%. The invention has the advantage that the transportation process of the metallized pellets is synchronized with the production of the rotary furnace and the arc furnace, thereby effectively reducing the heat loss of the metallized pellets and indirectly lowering the power consumption of the arc furnace. Besides, the invention ensures the pressurization in the transportationprocess so as to isolate the air, effectively inhibits the reoxidation reaction, and avoids increasing the smelting burden of the arc furnace.
