Cast belt continuous furnaces
Main Features:
- Fully automated lines
- No need of thooted rollers, due to a patented system that insures longer conveyor belt life
- Oil layer separation system, working without any leakage
- Effective heating system with U-shaped radiant tubes and external heat recuperators, requiring no maintenance
- Quality treatments, according to customer’s need, achievable through a supervising system
- The tempering furnace, equipped with a re-circulated gas direct flame heating system, allows a very high energetic efficiency while producing a protective atmosphere that is able to burnish the treated pieces
General Purpouse:
- Carbonitriding
- Hardening
- Suitable for Fasteners
The plant is set up as follows:
- An automated loading system including a case elevator, a vibrating Hopper, a dosing and weighting system
- A washing system for degreasing, dephosphating and drying
- A conveyor belt that feeds the furnace loading system
- A vibrating loading system for the hardening furnace that achieves uniform piece distribution on the conveyor belt (with such a system, loading happens with no danger for threads, since bolts suffer no shocks)
- A hardening furnace with a conveyor belt especially suited for fasterners with a minumum diamenter of 3 mm
- An oil quenching pit equipped with a conveyor belt and oil stirring and cooling systems
- An intermediate gas-heated washer with alkaline detergent
- A further vibrator for the tempering furnace, similar to the one feeding the hardening furnace
- A continuous tempering furnace with direct flame heating
- A pit for cooling in soluble oil, equipped with a conveyor belt
- A control board for managing the whole line
- A supervising system including a Siemens PLC and a Holo-View station, housed in external PC
- An oxygen probe and a Holo-Carb La Fornitecnica regulator to control and regulate the carbón potential
