Abstract
A system for transferring a steel slab from a first roller table to a second roller table by lifting the top slab from a stack of slabs on the first table, and then transferring and lowering the slab onto the second table. Specifically, a gantry-type bridge trolley mechanism having suspended electromagnets is provided that is motor driven on a cantilevered runway over the slab unpiler table and the furnace table. A stabilizer system minimizes sway of the electromagnets and the slabs.
Claims11
A system for transferring slabs from a stack of slabs to a furnace charging table comprising:
- a carriage selectively positionable over said stack of slabs and over said furnace charging table;
- a plurality of electromagnets coupled to said carriage to lift a slab off of said stack of slabs and transfer it to said furnace charging table;
- wherein each said electromagnet is connected to a vertical rod and each said vertical rod is connected to a horizontal shaft;
- and
- stabilizing means for limiting sway of at least one of the vertical rods.
A system for transferring slabs from a stack of slabs to a furnace charging table comprising:
- a carriage selectively positionable over said stack of slabs and over said furnace charging table;
- a plurality of electromagnets to said carriage to lift a slab off of said stack of slabs and transfer it to said furnace charging table;
- wherein each said electromagnet is connected to a vertical rod and each said vertical rod is connected to a horizontal shaft;
- and
- a plurality of stabilization arms each pivotally connected to said carriage and to one of said vertical rods.
A system for transferring slabs from a stack of slabs to a furnace charging table comprising:
- a carriage selectively positionable over said stack of slabs and over said furnace charging table;
- a plurality of electromagnets coupled to said carriage to lift a slab off of said stack of slabs and transfer it to said furnace charging table;
- and
- wherein each said electromagnet is connected to a vertical rod;
- wherein each electromagnet is suspended by at least one chain linkage having one end connected to said electromagnet and the opposite end connected to a horizontal disk pivotally connected to the lower end of the vertical rod.
A system for transferring slabs from a stack of slabs to a furnace charging table comprising:
- a carriage selectively positionable over said stack of slabs and over said furnace charging table;
- a plurality of electromagnets coupled to said carriage to lift a slab off of said stack of slabs and transfer it to said furnace charging table;
- and
- wherein each said electromagnet is connected to a vertical rod and each said vertical rod is connected to a horizontal shaft;
- wherein each vertical rod is connected to said horizontal shaft by a lever arm.
A system for transferring slabs from a stack of slabs comprising:
- a carriage selectively positionable over said stack of slabs at a first position and a second position spaced from the first position;
- a plurality of electromagnets coupled to said carriage to lift a slab off of said stack of slabs and transfer it to said second position;
- wherein each said electromagnet is connected to a vertical rod;
- and
- stabilizing means for limiting sway of at least one of the vertical rods.
