1. Okay for small &big production capacity as threaded rod heated continuous one by one, and also the machine can start &stop work by only press a bottom
2. The quality of finished product highly improved as single pieces continuous faster heating to avoid seriously oxidation &decarbonization (carbon lost along with heating)
3. Power and water can support the running of whole system , no pollution, good for environment
4. Hardening, tempering, surface finishing (to avoid oxidation) can be finished in one production line
Application: Continuous hardening and tempering
Grade: 8.8, 10.9, 12.9
Machine for hardening
Machine for Tempering
