Conveyor furnace FR series

pittemperingquenching

FR SERIES 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 séparation System, working withoutany 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 atmosphère that is able to burnish the treated pièces 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
