Bar Tunnel Furnace Systems

Continuous High Volume Production with Integrated Hardening, Quenching and Tempering

CAN-ENG Tunnel Furnace steel bar heat treatment systems have fully integrated hardening, quenching and tempering for high volume and continuous production up to 9 metric tons/hr (20,000 lbs/hr).

CAN-ENG's unique spray quenching technology maintains bar straightness and provides for extremely uniform metallurgical and mechanical properties. Post heat treatment straightening is eliminated making it possible for "stress free" bar production meeting commercial quality straightness of 3 mm per 1.5 m (1/8" in 5').
