FEEDER CONVEYOR ASSEMBLY
Feeder Conveyor

Feed Conveyor feeds billets one-by-one to billet lifter device & pusher. At the start conveyor moves one full length, so that one billet is pushed to a lifting tray on same level of roller.
The Feed Conveyor is driven by Geared Motor with Chain Sprocket Arrangement. The Conveyor Will forward & Reverse facility (Electrically) is Provided . Supporting structure is provided to accommodate the feed rollers, drive unit for feed conveyor and Billet guide to guide the Billet.
BILLET HANDLING ROLLER CONVEYOR SYSTEM
The cold billets are lifted one by one from ground level of pallet/Tot box with Monorail Crane. Permanent magnet lifter attached with hook of Monorail crane and magnet lifter having UP and DOWN ,FORWARD and REVERSE, ON /OFF hand lever operation. For safety purpose of lever striker (locker) is provided. When the permanent magnet on the billet surface from the ground level, Turn the magnet lever to ON position and lock the lever. Now the Billet will be held by the magnet device.
- Normally Billet is lifted from Ground 0 level to approximate 1.00 Mt.

- The Billet lifted with Magnet Device will move to the centerline of the Conveyor and placed on the damper tray of the feed Conveyor.
BILLET EXTRACTOR WITH ACCEPT/REJECT DEVICE
The hot billet comes out of the induction coil is received by the billet extractor conveyor and stopped by the stopper gate arrangements at the end of the conveyor. The Stopper is operated by the hydraulic Cylinder.

The hot billet is sensed by (HMT) temperature sensor. If the temperature is within the acceptable range the stopper plate will open and the billet is taken for next operation.
If the temperature is not within acceptable range, the billet is discarded with the help of Discarder fingers placed in between rollers of extractor. Discarder fingers are below the roller line while normal operation to avoid any obstruction. Discarder is operated by the hydraulic cylinder.
BILLET LIFTER ASSEMBLY
When feed conveyor moves, one full billet comes on this tray. The Billet received from the feed conveyor to the lifter. Then the Billet is lifted by the lifter to the passing through induction Coil. Lifting cylinder speed is controlled by flow control valve, while return stroke is fast. Tray will orient the billet at induction coil in flat face position. Limit Switches are provided to control the stoke length of cylinder.

BILLET PUSHER
The billet is aligned along the coil, is pushed into the induction coil by pusher mechanics fixed to the feed conveyor structure. The Pusher mechanics consists of hydraulic cylinders attached with the pushing ram guided by rollers. The stroke of pusher is adjustable for various sizes/ lengths of billets so that on completion of one pushing stroke one full hot billet comes out at the out feed end of induction coil.
DAMPER ASSEMBLY
A damper tray having provision to move up/down 90mm vertically with help of 4 nos of guide pushes & guide rods provided at the start of rollers of feed conveyor. At the beginning of process tray remain up & billet is placed on tray in flat position. Tray goes down after receiving the billet & places it on roller feed conveyor in flat position. The Tray up/down vertical motion controlled by Hydraulic Cylinder. Limit switches provided for indication the hydraulic cylinder motion.
BILLET DISCHARGE CONVEYOR
Discharge Conveyor
