arc furnace slagging door

The slag door can also incorporate wing walls disposed in close proximity to the sides of the slag door.

The slag door can be disposed in close proximity to the hearth of the furnace to eliminate problems associate with conventional slag door tunnels.

The wing walls can minimize air infiltration into the furnace when the slag door is in an open position.

The apparatus may also have at least one wiping component moveable so as to sweep across the lower surface of the slag door to remove obstructions.

The slag door can pivot from the top using one or more robust mechanisms that enable the door to be moved into and stopped in any position between a closed position and an open position.
