Abstract

DC60 (28/05/41) Filling system for electric arc furnaces (11), which at least The roof section (11a), which has at least the fourth hole. It can be connected to a conduit to emit smoke (22), coupled with an airtight hood (23) at its end, to temporarily close the containment element (16) that contains at least one scrap metal. Where the lower part of the containment element (16) can be opened as This is a partial minimum. For holding up and sliding (15), at least at the very least, a rotating manipulator arm (17) is installed, where the body Assembled for containers (16) that are arranged in the station. Preheating (20b) works in direct interaction with the mechanism. The fumes are transported from the furnace (11) and with a temporary shut-off mechanism (23) where the packing elements (16) are configured in the form of a container or basket (12, 112, 212) that are Arrange in such a way that the detachable paused on the holding assembly (17a, 17b) of the carrier arm (17) and the container or basket (12, 112, 212) in the supplying station. Preheat (20b) is arranged above and in such a way that it is directly shared with the combustion chamber (21), where the smoke for Preheating is passed and is partially burnt after it has passed through a container or basket (12), passing metal scraps from top to bottom. The airtight cover (23) of the container or basket (12) can be released vertically and in a rotating manner. And is temporarily connected directly to the conduit The smoke is emitted (22) from the fourth hole of the furnace (11) by at least partially the guide triggers that are joined to the axis. The filling system for electric arc furnaces (11), which has at least a roof section (11a) with at least a "fourth hole" section. It can be connected to a pipe to release smoke (22), coupled with a pass-through hood (23) at its end. To temporarily close the packing element (16) containing at least one scrap, where The bottom of the containment element (16) can be fully opened. Partial Which this system will consist of equipment For holding up and sliding (15) that at the very least have arms that Is a rotary manipulator (17) mounted, where the Assembled for containers (16) that are arranged in the station. Preheating (20b) works in direct interaction with the mechanism. The fumes are transported from the furnace (11) and with a temporary shut-off mechanism (23), where the packing elements (16) are configured in the form of containers or baskets (12,112,212) arranged in such a way. Removable, suspended on lump The mounts (17a, 17b) of the shrug arms (17) and the container or basket (12,112,212) in the pre-heat station (20b) are arranged directly above and in a joint manner. With the chambers (21) which smoke for Preheating will pass It was partially burnt after it had passed through a container or basket (12) through metal scraps from top to bottom. The airtight cover (23) of the container or basket (12) can be released vertically and in a rotating manner. It was temporarily connected directly to the conduit that emitted smoke (22) from the fourth hole of the furnace (11) by at least partially the guide triggers that were joined to the axial axis.

Claims (1)

1. Filling systems for arc furnaces (11), regardless of the type that is fed by direct current. Or alternating current Which, at the very least The electric arc furnace (11) has a roof section (11a) that can be moved from the closed position. Can be positioned on the side where there is no interference At the very least, the roof (11a) will have a "fourth hole" that can be attached to a conduit to emit smoke (22) attached to the hood. That does not let air pass (23) at its end To temporarily turn off at least one packing element (16), tag:
