Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
