Claims12
A slag door for a melting furnace for the production of steel, suitable to be associated with an aperture provided in a lateral wall of the melting furnace and to cooperate with a slag channel provided inside the melting furnace itself, wherein it is comprised:
- a frame on which a sliding closing panel is mounted, configured to selectively assume a lowered position to close said slag channel, in which a lower part of the closing panel substantially abuts on a base surface of the slag channel and a raised position to open said slag channel in which the closing panel is partly or completely raised;
- a slag removal device, mounted on said frame and mobile with respect to it, provided at least with a cleaning arm and having at its end a cleaning element configured to be moved inside the slag channel when the closing panel is in the raised position;
- said slag removal device having a working operating position, when the sliding closing panel is located in the raised opening position, in which the cleaning element moves until it penetrates through the aperture of the melting furnace along the slag channel and exerts its cleaning and descaling action of the slag present in said slag channel, and an inactive operating position in which it is raised and outside the bulk of said aperture of the melting furnace, and
- wherein the connection between the slag removal device and the frame is of the hinge type.
