Segmented Wiping Members for Low-Leakage Rolling Facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rolling facilities, wiping apparatuses with single structures require full replacement upon partial defects, leading to increased maintenance costs and potential coolant leakage issues.
Innovation Solution
A wiping apparatus with a plurality of divided members arranged along the extension direction, allowing for partial replacement of defective members and reducing maintenance costs, while preventing coolant leakage through strategically designed end surfaces and elastic members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single structure wiper is used, then the structure is simple, but the maintenance cost increases when partial defects occur
Solution Approach 1:
The wiper is divided into multiple independent wiping elements arranged along the width direction. Each element can be independently replaced when defective, rather than replacing the entire wiper assembly. This segmentation reduces maintenance costs while maintaining the simplicity of each individual element's structure.
2Device complexity
If a single structure wiper is used, then the structure is simple, but coolant leakage occurs when defects happen
Solution Approach 1:
The wiper is segmented into multiple independent wiping elements with individual support structures. When one element becomes defective or detached, the other elements remain functional and continue to prevent coolant leakage. This segmentation isolates failures to specific elements rather than affecting the entire wiper system.
Solution Approach 2:
Each wiping element has its own support structure and contact characteristics optimized for its specific position on the strip width. This local optimization ensures that each element effectively addresses coolant removal at its location, and failures in one location do not compromise the functionality of other locations.
3Length of stationary object
If a long single structure wiper is used, then the wiping coverage is complete, but the entire wiper must be replaced for partial defects
Solution Approach 1:
The long wiper is divided into multiple smaller wiping elements arranged along the width direction. Each element covers a specific portion of the strip width, collectively providing complete coverage. When a defect occurs in one element, only that specific element needs replacement, not the entire long wiper structure.
4Ease of repair
If divided members are used, then maintenance cost reduces, but the device complexity increases
Solution Approach 1:
The wiper is segmented into multiple independent wiping elements that are relatively simple in structure. Each element consists of a support structure and wiping portion, maintaining simplicity while enabling independent replacement. The segmentation is achieved through simple connection mechanisms that do not significantly complicate the overall device.
