The invention belongs to the metallurgy technical field and discloses an electric stove metal bulk cargo continuous feeding and preheating device and method. The metal charge roller preheating grooveof the device is inclined with the horizontal plane, the lower end of the metal charge roller preheating groove is inserted into the inlet of a stove entering vibratory conveyor to be sheathed in short distance fit, the stove entering vibratory conveyor is connected with open pore A of the electric stove, the position of approach end is lower, the higher end of the metal charge roller preheating groove is sheathed and combined with a groove entering vibratory conveying and air sealing device, and the two are sheathed in short distance fit. The method is characterized in that metal charge is fed into the metal charge roller preheating groove to be preheated. The preheated metal charge is fed into the electric stove, and smoke of the electric stove is exhausted by the stove entering vibratory conveyor, the metal charge preheating groove and the groove entering vibratory conveying and air sealing device. The invention has the advantages of less electrical energy consumption, steady operation, high scrap preheating efficiency, high operational throughput and short total device length and is a new energy-saving and environmentally friendly technology with promotional value on electric stove or other production technologies.
