Abstract
An arc metallurgic furnace slagging door having an upper panel and a lower panel substantially vertically aligned with the upper panel, the panels being placed in front of a tunnel giving access to a furnace melting pot and in front of the slagging door for closing the tunnel. The upper panel is outwardly inclined with respect to the tunnel, and movable between a closed position and an open position which permits remarks and interventions to be conducted on molten metal. The lower panel is movable independently with respect to the upper panel between closing, cleaning and slagging positions.

A slagging door for an arc metallurgic furnace having a furnace wall, a melting pot, and a tunnel to receive molten metal, and, the slagging door comprising:
- a carrier connected to the arc metallurgic furnace;
- a guide supported by the carrier and which is outwardly inclined with respect to the furnace wall;
- an upper panel mounted on the carrier and which is slidingly movable upwardly and outwardly on the guide between a closed position, and an open position which permits remarks and interventions to be conducted on the molten metal, and intermediate positions;
- a lower panel connected to the upper panel, and movable relative to the tunnel between a closing position, a cleaning position, and a slagging position, and also movable to partially rise, partially lower, partially advance into the arc metallurgic furnace, and partially back out of the arc metallurgic furnace to both remove slag present in the melting pot, and push various material inside the arc metallurgic furnace;
- a first actuator connected to the carrier and the upper panel to drive the upper panel between the closed position, the open position, and the intermediate positions;
- and
- a second actuator connected to the carrier and the lower panel to drive the lower panel between the closing position, the cleaning position, and the slagging position.
A slagging door for an arc metallurgic furnace having a furnace wall, a melting pot, and a tunnel to receive molten metal, and, the slagging door comprising:
- a carrier connected to the arc metallurgic furnace;
- a guide connected to the carrier at an incline relative to the furnace wall;
- an upper panel mounted on the guide for movement in upward and downward directions relative to the tunnel and between a closed position, and an open position which permits remarks and interventions to be conducted on the molten metal, and intermediate positions;
- a lower panel operatively connected to the upper panel, and movable relative to the tunnel between a closing position, a cleaning position and a slagging position, and also movable to partially rise, partially lower, partially advance into the arc metallurgic furnace, and partially back out of the arc metallurgic furnace to both remove slag present in the melting pot, and push various material inside the arc metallurgic furnace;
- a first hydraulic actuator to drive the upper panel, the first hydraulic actuator having at least one hydraulic cylinder operatively connected to the upper panel;
- and
- a second hydraulic actuator to drive the lower panel between the closing position, the cleaning position, and the slagging position.
A furnace, comprising:
- a furnace melting pot;
- a furnace wall;
- a tunnel;
- and
- a slagging door including:
- a carrier connected to the furnace wall;
- a guide connected to the carrier and which is outwardly inclined with respect to the furnace wall;
- an upper panel mounted on the guide for movement between a closed position, and an open position which permits remarks and interventions to be conducted on the molten metal, and intermediate positions;
- a lower panel operatively connected to the upper panel, and movable relative to the tunnel between a closing position, a cleaning position and a slagging position, and also movable to partially rise, partially lower, partially advance into the arc metallurgic furnace, and partially back out of the arc metallurgic furnace to both remove slag present in the melting pot, and push various material inside the arc metallurgic furnace;
- a first actuator connected to the carrier and the upper panel to drive the upper panel between the closed position, the open position, and the intermediate positions;
- and
- a second actuator connected to the carrier and the lower panel to drive the lower panel between the closing position, the cleaning position, and the slagging position.
