Frequently Asked Questions
What types of metals can be processed by these tempering mills?
All models (650, 750, 850, and 1000) are engineered to process both normal carbon steel and stainless steel coils effectively.
What is the maximum line speed available across the models?
The line speed ranges from 180 m/min up to a maximum of 600 m/min, depending on the model selected (Model 1000 delivers 240~600 m/min).
What mill type configurations are available?
Models 650 and 750 offer choices of 2-roll or 4-roll configurations, while larger models 850 and 1000 come standard with 4-roll configurations for higher tempering force.
What is the typical elongation rate achievable?
All models maintain a consistent, high-precision elongation control range of 0.2% to 3.0% to improve strip mechanical properties and flatness.
What driving method and motors are utilized in the system?
The system utilizes working roll driving with Z4 series motors powering the main drive, uncoiler, recoiler, and S rolls, driven by a 10 MPa hydraulic station pressure.
Can these technical parameters be customized for specific plant needs?
Yes. The parameters shown in the table serve as reference specifications. Both machine design and production parameters can be tailor-made to match your operational requirements.
