End Dump Charger System

Characteristics:

• System is capable of handling up to six charges per hour using ingot or scrap delivered by charge bucket.
• Cycle time for bucket ascent, dump, and descent is approximately one minute.
• Includes 3 HP hydraulic power pack with lift cylinders, valving, and piping; comes completely assembled.
• Nonflammable fluid is used throughout the system.
• Charger access gate is interlocked by a limit switch as an additional safety feature to prevent charger operation when gate is open.
• Charger controls include a stockline indicator to prevent Jet Melter overcharging.

Sequence of Operations:

1. Operator places the charge materials (ingots & scrap) into the charge bucket through the open top.
2. Operator initiates charge cycle and PLC verifies, via photo eye sensor, there is adequate room in the stack.
3. The loaded bucket proceeds up the track.
4. The stack cover opens automatically and melting burners go to Low fire.

• The upper terminal limit switch verifies that the cover has fully opened, stops the bucket's upward movement, and starts the tilting operation, depositing the charge material the furnace shaft.
• After a short delay at the top, the empty bucket will automatically return to the bottom position and the stack cover will close.
• The melting burners return to high fire and continue to melt.
