A sealed feeder device utilized in an electric arc furnace (), and a flue gas and temperature control method. The sealed feeder device comprises a sealed feeding chute () having an outlet sealedly communicating with a side wall of the electric arc furnace (), and a material blocking sealed arc-shaped door () disposed in the sealed feeding chute (). The material blocking sealed arc-shaped door () separates the sealed feeding chute () into a cold steel scrap storage chamber () and a material feeding and dedusting chamber (), and is operated by a driving mechanism () to separate or connect the cold steel scrap storage chamber () and the material feeding and dedusting chamber (). The method comprises: adopting the feeder device to divide the flue gas of the electric arc furnace () into two paths, and controlling, by a flue gas adjustment device (), a ratio of a flue gas flow from a flow-splitting dust removal pipe () to that from a dust removal pipe () to obtain a required flue gas mixture temperature.

Feeder device utilized in electric arc furnace, and flue gas and temperature control method

The present invention belongs to the technical field of metallurgy, and discloses a horizontal continuous feeding preheating device and an enhanced preheating method therefor. The scheme comprises that two dust removal ports are arranged at the front and rear parts of a horizontal continuous feeding preheating duct, and the horizontal continuous feeding preheating duct is divided into an enhanced preheating area and a flue gas preheating area by the two dust removal ports arranged at the front and rear parts of the horizontal continuous feeding preheating duct; burners are installed in the enhanced preheating area, and the two dust removal ports are connected with a flue gas adjusting distributor respectively by a flue gas pipeline the steel scrap preheating efficiency of the burners and electric arc furnace flue gas is increased by controlling the flow rate and temperature of mixed flue gas.
