AUTOMATIC FEEDING APPARATUS FOR ELECTRIC ARC FURNACE

摘要

The present invention discloses an automatic feeding apparatus for an electric arc furnace, which comprises an automatic distributing device, wherein said automatic distributing device comprises a distributing tank, and at least one stepwise distributing section which is inclined from high to low along a material delivery direction is provided at the bottom of said distributing tank; and further comprises a thermal feeding device, a cold feeding device, and a loading device. The automatic distributing device of the present invention enables forward throwing of the materials when falling down, which eliminates the problem that the materials are difficult to be dispersed in overall movement, so that the materials can be effectively dispersed by vibration, the stacked materials can be uniformly and continuously distributed in the material tank, and the scrap steel stacking and blocking problems of the materials are prevented from occurring at a throat portion of the feeding apparatus; different thermal feeding devices thereof have advantages such as a good material preheating effect and environment friendliness; and the loading device thereof does not require a crane, so the operation is convenient, of high safety, and suitable for high-frequency material loading, and can satisfy operation frequency demands of continuous feeding for smelting of medium to large-scale electric arc furnaces.
