Quick-Change Roll Cooling Header Cartridge With Real-Time Wear Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roll cooling headers in rolling mills wear or clog over time, leading to sub-optimal cooling and requiring costly replacements due to inefficient maintenance practices, with existing solutions relying on visual inspection and resulting in waste and uneven cooling across mill rolls.
Innovation Solution
A split header design with a durable mounting block and a quick-change header cartridge, equipped with sensors and RFID tags, allows for real-time monitoring and alerts, enabling timely replacement and balancing of cooling pressures, along with a dummy header cartridge to divert water when stands are not in use, reducing waste and inventory needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual inspection methods are used to monitor cooling header condition, then operational simplicity is maintained, but detection precision and timeliness of header wear or clog identification deteriorates
Solution Approach 1:
The system implements real-time feedback through sensors that continuously monitor cooling header conditions (temperature, pressure, flow rate) and transmit data to a central computer, enabling timely detection of wear or clogs before they affect cooling performance
Solution Approach 2:
The patent replaces manual visual inspection with automated sensor-based monitoring systems, substituting mechanical/human observation methods with electronic detection devices that provide continuous, precise measurements of header condition
2Productivity
If cooling headers are replaced only after severe wear or clog occurs, then inventory costs and complexity are reduced, but productivity and cooling performance deteriorate due to sub-optimal roll cooling
Solution Approach 1:
The system performs preliminary detection of header wear and clog conditions through continuous sensor monitoring, allowing maintenance to be scheduled before severe degradation occurs, thus preventing downtime and maintaining productivity
Solution Approach 2:
Real-time feedback from sensors enables proactive maintenance scheduling based on actual header condition rather than fixed schedules, optimizing the timing of replacements to maintain cooling efficiency while minimizing downtime
3Reliability
If entire cooling headers are replaced due to localized wear or clog, then reliability is restored, but loss of substance and manufacturing costs increase due to waste
Solution Approach 1:
The cooling header system is segmented into modular cartridges that can be individually replaced based on their specific condition, allowing the remaining functional portions of the header assembly to continue operating and reducing material waste
Solution Approach 2:
The patent applies local quality by monitoring and replacing only the specific cartridges that exhibit wear or clog conditions, rather than replacing the entire header assembly, thus maintaining reliability where needed while minimizing waste in areas that are still functional
4Ease of operation
If quick-change header cartridges are used instead of traditional headers, then ease of operation and maintenance are improved, but device complexity increases due to additional components and assembly requirements
Solution Approach 1:
The header is divided into a permanent mounting block and replaceable cartridges, with the mounting block containing complex features (sensors, sealing surfaces, water distribution) that remain in place, while simpler cartridges are easily swapped, improving maintenance ease without permanently increasing overall system complexity
Solution Approach 2:
The universal mounting block design can accommodate multiple cartridge types and includes integrated sensor and sealing features, allowing a single complex component to serve multiple functions and reduce the need for additional specialized parts

AI summary
Disclosed is a novel split header for use in a rolling mill. The split header has a mounting block and a quick-change header cartridge, wherein the mounting block is coupled to the quick-change header via a quick-disconnect feature, the quick-disconnect feature configured to enable uncoupling (in a toolless manner) of the quick-change header from the mounting block. Additionally, the quick-change header cartridge may be replaced by a dummy header cartridge that diverts water when stand is dummied, and a split base and header cartridge design. Further, the mounting block may have one or more sensors and the quick-change header may have an RFID tag, where the sensors and the RFID tag may communicate with a central computer.
