Frequently Asked Questions
What materials are compatible with these tempering mill models?
All four models (650, 750, 850, and 1000) are compatible with both normal carbon steel and stainless steel, making them highly versatile for various industrial steel processing applications.
What is the maximum line speed achievable with the Model 1000 tempering mill?
The Model 1000 supports the highest line speed range among the four models, operating between 240 and 600 m/min, making it ideal for high-efficiency, high-throughput production lines.
What is the difference between the 2-roll and 4-roll tempering mill configurations?
The 2-roll configuration is available on the Model 650 and 750 for lighter processing needs, while the 4-roll configuration — available on all models — provides greater rolling force and is better suited for higher elongation rates and thicker materials requiring more precise flatness control.
Can the technical parameters be customized according to specific production requirements?
Yes. All models and parameters listed in the technical table are for reference purposes only. The design and manufacturing can be fully tailor-made to meet individual user specifications, including material width, thickness range, line speed, and tempering force requirements.
What type of motor is used across all tempering mill models?
All models use Z4 series DC motors for the main drive, uncoiler, recoiler, and S roll functions. The specific motor ratings (marked as "omit" in the table) can be confirmed and customized based on the actual production line configuration.
What hydraulic station pressure is required for operating these tempering mills?
All four models — 650, 750, 850, and 1000 — operate at a standard hydraulic station pressure of 10 MPa, ensuring consistent hydraulic performance across the entire product range.
