The Φ 80 long bar induction hardening and tempering machine is a typical non-standard equipment that requires customized design based on steel grade, production capacity, and process requirements. Hebei Forever Electromechanical has multiple mature cases in this field for reference by enterprises in need.
Case 1: Low alloy steel bar project of Shigang Group
Specification range: Φ 60- Φ 80 steel bar
Design cycle: 2.0 tons/hour
Scheme configuration: Two 800kW intermediate frequency power supplies are connected in parallel, with zone heating, segmented spray cooling, and induction tempering.
Result: The hardness uniformity after hardening and tempering is controlled at ± 2HRC, meeting the customer's requirements for impact toughness.

Case 2: Japan's Eastern Heat Changzhou Project
Specification range: Φ 40- Φ 80 steel rod
Highlights of the solution: Equipped with infrared temperature measurement and process database, enabling one click switching between different steel grades.
Result: After the production line is put into operation, the steel bar induction hardening and tempering furnace runs stably and consumes less energy than traditional solutions.
Case 3: Philippine API 5CT Energy Enterprise
Specification range: compatible with oil casing for steel bars ranging from Φ 80 to Φ 120
Export plan: Equipped with a multilingual operating interface, the electrical system meets local standards, and Far Eastern engineers are dispatched for on-site debugging to ensure rapid production.
