Frequently Asked Questions (FAQ)
What raw materials can be processed by these tempering mills?
The mill units are engineered to process both normal carbon steel and various grades of stainless steel with thickness ranges from 0.16 mm to 1.5 mm.
What is the achievable line speed range across different models?
Depending on the model chosen, the production line speed operates between 180 m/min and up to 600 m/min for high-capacity applications like the Model 1000.
How does 2-roll compare to 4-roll tempering mill configurations?
Models 650 and 750 offer flexible configurations of either 2-roll or 4-roll types, whereas higher-load models (850 and 1000) utilize 4-roll systems to handle greater tempering forces (up to 2500 KN) and wider strip widths.
What elongation rate control accuracy can be achieved?
All models provide precise elongation rate control between 0.2% and 3.0%, ensuring optimal strip flatness, mechanical properties, and surface finish.
What drive system and hydraulic pressures are standard?
The machines utilize a direct working roll drive configuration powered by high-performance Z4 series DC/AC motors, supported by a 10 MPa working hydraulic station pressure.
Can line specifications be customized for non-standard strip widths?
Yes, all technical parameters listed are baseline configurations. Complete design, mill layout, and auxiliary systems can be custom-tailored to your specific factory layout and operational specifications.
