Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll cooling devices require significant coolant amounts, have complex constructions, and require manual adjustment, leading to inefficiencies and high costs due to frequent roll changes in rolling mills.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of cooling gap is performed, then adjustment precision can be achieved, but time consumption and labor costs increase significantly
Solution Approach 1:
The cooling device performs self-adjustment through the lever mechanism that automatically adapts the cooling gap to different roll diameters. The lever pivots about a suspension point and uses the roll itself as the reference surface, eliminating the need for external manual measurement and adjustment operations.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated mechanical lever system. The lever mechanism converts the physical contact with the roll surface into automatic positioning, substituting human operators with a self-actuating mechanical system that responds to roll geometry.
2Area of stationary object
If multiple cooling shell segments are used, then cooling coverage is improved, but device complexity increases
Solution Approach 1:
The cooling shell is divided into multiple segments that can be independently positioned and adjusted. Each segment can be adapted to different roll surfaces while maintaining proper cooling coverage, allowing modular assembly and simplified maintenance without requiring complete device replacement.
3Stability of the object's composition
If cooling shell is coupled to roll stand, then stable positioning is achieved, but adaptability to different rolls decreases
Solution Approach 1:
The cooling device incorporates dynamic adjustment capabilities through the lever mechanism that can pivot and adapt its position. The system transitions from a fixed rigid connection to a dynamic adjustable connection, allowing the cooling gap to vary automatically with different roll diameters while maintaining stable operation during each rolling process.

AI summary
A device for cooling a roll for rolling materials, including a cooling shell opposite a sub-region of the roll surface circumference, for forming a cooling gap, through which a cooling fluid can flow, between the sub-region and the cooling shell. The device further includes a first lever which can be pivoted about a suspension point, which can be pivoted toward the roll surface, and which is rotatably connected to a first end region of the cooling shell, when viewed in the circumferential direction of the roll, and a second lever which can be pivoted about another suspension point, which can be pivoted toward the roll surface, and which is rotatably connected to the second end region of the cooling shell, when viewed in the circumferential direction of the roll, such that the cooling gap can be selectively reduced or increased by pivoting the levers.
