Spray Bar Tilt Layout for Faster Rolling Mill Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling mills face challenges in efficiently maintaining and replacing cylinders due to the tedious and time-consuming process of dismantling ramp tilting devices, which often results in the risk of catching hoses and requiring complex decoupling of actuators and supply means during maintenance.
Innovation Solution
A rolling mill design with a tilt adjustment device actuator positioned on the side opposite the maintenance window, allowing ramps to be extracted without decoupling the actuator or supply means, utilizing a removable connector and articulation mechanism to facilitate easy ramp extraction through the maintenance window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuator is positioned on the same side as the maintenance window, then it is easier to access during maintenance, but the ramp cannot be extracted without decoupling the actuator and supply means, increasing maintenance complexity and time
Solution Approach 1:
The actuator is extracted from the maintenance window side and positioned on the opposite side, separating it from the ramp extraction path. This allows the ramp to be removed through the maintenance window without requiring decoupling of the actuator or supply means, as these components remain positioned on the opposite side of the cage.
2Ease of operation
If the actuator and supply means are positioned on the maintenance window side, then maintenance access is improved, but hoses may be caught during cylinder extraction, creating safety risks
Solution Approach 1:
The actuator and supply means are extracted from the maintenance window side and repositioned on the opposite side. This spatial separation ensures that hoses and actuators do not interfere with cylinder extraction operations through the maintenance window, eliminating the risk of hose entanglement while maintaining ease of access to the maintenance window for ramp removal.
3Volume of moving object
If the ramp tilting device components are positioned on the maintenance window side, then the structure is more compact, but ramp extraction requires tedious dismantling of multiple components
Solution Approach 1:
The actuator and supply means are extracted from the maintenance window side and positioned on the opposite side. This allows the ramp to be quickly removed through the maintenance window without requiring dismantling of the tilting device components, significantly reducing maintenance time while the overall structure remains compact as these extracted components occupy space on the opposite side.

AI summary
This disclosure relates to a rolling mill, specifically a cold rolling mill, comprising: - cylinders or sets of rollers including at least one pair of working cylinders capable of defining the air gap of a strip to be rolled, - at least one spray bar (3a, 3b) for spraying a lubricating and/or cooling fluid, located near the plane of the strip to be rolled, - a stand (2) within which said cylinders are arranged, - at least one device for adjusting the inclination of said at least one spray bar including an actuator, such as a hydraulic cylinder configured to change the inclination of the spray bar about the pivot axis. According to this disclosure, said actuator of the inclination adjustment device is arranged on the second side (C2) of the stand, opposite the first side (C1) of the maintenance window.
