Abrégé
(EN)

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 negative pressure of a second dust removal port is balanced by the efflux fluid dynamic pressure of a plurality rows of burners in the enhanced preheating area; the micro-negative pressure requirement of a first dust removal port is controlled by a pressure sensor, so as to reduce the amount of cold air mixed into the first dust removal port, 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, and the production is made more environment-friendly.
