Long bar heat treating is induction heating for Quench and Tempered Bars. Heat treatments available by heat treating line are Quench and Temper, Stress Relieving, Through Hardening, Surface Hardening.

- Suitable for small and large production capacity as threaded rods are heated continuously one by one
- Machine can start and stop work with a single button press
- Quality of finished product is highly improved due to single pieces continuous faster heating, avoiding serious oxidation and decarbonization
- Power and water support the running of the whole system with no pollution, environmentally friendly
- Hardening, tempering, and surface finishing (to avoid oxidation) can be completed in one production line
Duolin long bar heat treating line can process bar sizes from 6-100mm, lengths from 1000-14000, meeting both small and large production capacity requirements.
Application: Continuous hardening and tempering
Length: 1000-14000
Grade: 8.8, 10.9, 12.9
