1.How can we pinpoint where the "non-standard" aspect lies?
The most crucial element is "thickness tolerance." You need to be clear about whether, for example, a 0.5mm thick cold-rolled coil, you want ±0.03mm or ±0.01mm. In addition, flatness (such as unevenness requirements) and surface roughness may also fall under the category of "high precision."
2.How to find the right "partner"?
Not all steel mills can do this. You need to look for manufacturers with advanced rolling mills (such as 20-roll or 6-roll mills) and automated control systems, like Liuzhou Steel and Henan Steel in the case studies. They typically have stronger "extreme manufacturing" capabilities.
3.How to prepare for a "customized cycle"?
Adjusting the process model: such as resetting rolling force, tension, and roll profile curves.
Possible equipment modifications: similar to the upgrade of core components of the pickling and rolling model by Henan Iron and Steel in collaboration with Northeastern University.
Longer delivery time: From trial to stable production, it may require more than a month of technical preparation.
4.What about the product thickness and precision?
0.12mm stainless steel coil
±1.5 micrometers (μm)
equivalent to approximately 1/50th the diameter of a human hair, setting a new record for ultra-thinness.
5.What is the machining precision required for cold-rolled steel sheets?
Width processing accuracy ±0.05mm. This high-precision level in shearing processes serves the consumer electronics industry.
