Solution Overview
Problem
Existing methods for changing the temperature of metal strips, particularly aluminum or aluminum alloy strips, face challenges in achieving precise temperature control and minimizing thermal stresses, leading to flatness defects during heating and cooling processes.
Innovation Solution
A device with individually adjustable temperature-control means that can be translated and rotated relative to the metal strip, allowing for precise temperature control and reduced thermal stresses by adjusting the position and heating/cooling power of temperature-control means based on flatness measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high heating and cooling rates are used to achieve rapid temperature change, then productivity is improved, but manufacturing precision deteriorates due to thermal stresses causing distortions and flatness defects
Solution Approach 1:
The continuous metal strip is divided into multiple transverse zones, each equipped with independent temperature-control means. This segmentation allows different regions of the strip to be heated or cooled at different rates and to different temperature levels, enabling rapid overall temperature change while maintaining flatness by compensating for thermal stresses in each zone individually
Solution Approach 2:
Each transverse zone receives customized temperature control based on its specific requirements. The temperature-control means are individually adjustable in position and heating/cooling power, allowing local adaptation to minimize thermal stresses and prevent distortions in each region while achieving the desired overall temperature change rapidly
2Device complexity
If temperature-control means are fixed in position, then device complexity is reduced, but manufacturing precision deteriorates due to inability to optimize temperature distribution for flatness control
Solution Approach 1:
The temperature-control means are made dynamically adjustable rather than fixed. Each temperature-control means can be individually positioned and oriented according to the specific requirements of different transverse zones, allowing the system to adapt to varying temperature distribution needs while maintaining a relatively simple overall device structure
