Cooling Bar Partition Layout for Uniform Metal Strip Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices for metallic products struggle to uniformly distribute coolant across the width of a metal strip, leading to inefficient temperature control and non-uniform cooling.
Innovation Solution
The cooling device is enhanced by dividing the cooling bar into multiple chambers with partition walls that follow the temperature distribution of the metal strip, allowing for variable coolant flow and nozzle arrangement to achieve targeted cooling, with movable partition walls and a control system to adjust coolant distribution dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cooling bar is divided into individual spraying regions with controllable valves, then the cooling can be adapted to the temperature distribution across the width of the product, but the device complexity increases due to multiple valves and control systems
Solution Approach 1:
The cooling bar is divided into multiple spraying regions along its longitudinal extent, with each region having independently controllable valves. This segmentation allows different sections of the cooling bar to be controlled independently, enabling adaptation to the temperature distribution across the width of the metallic product while maintaining manageable system complexity through modular design
Solution Approach 2:
Different spraying regions are assigned different cooling characteristics based on the local temperature requirements of the metallic product. The partition walls create distinct chambers that can be individually adjusted to provide localized cooling quality matching the temperature profile across the product width
2Adaptability or versatility
If the partition walls are made movable to variable positioning, then the starting point of degressive decrease or positive increase of coolant volume flow can be variably set, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The partition walls are designed to be movable rather than fixed, allowing them to be positioned at different locations along the longitudinal extent of the cooling bar. This dynamic positioning capability enables variable adjustment of the starting point for degressive decrease or positive increase of coolant volume flow, adapting to different cooling requirements while maintaining a relatively simple mechanical implementation
3Productivity
If the partition wall is shaped according to the temperature distribution course, then the cooling is particularly effective and targeted, but the manufacturing precision requirements increase
Solution Approach 1:
The partition walls are shaped according to the temperature distribution course across the width of the metallic product, creating a profile that mirrors the temperature profile. This allows each section of the partition wall to provide locally optimized cooling, with the shape directly corresponding to the thermal requirements of different product zones
Solution Approach 2:
The partition walls are pre-shaped according to the expected or measured temperature distribution pattern before the cooling process begins. This preliminary configuration of the partition wall geometry allows the system to be pre-adapted to the temperature profile, enabling effective cooling without requiring complex real-time adjustments during operation

AI summary
A cooling device for cooling a metallic product has at least one cooling bar with a plurality of spraying regions which are adjacent in pairs defined by one or more moveable partition walls. Each spraying region has at least one spray nozzle for spraying a coolant onto the metallic product. A control device controls a pump and valves for individually adjusting pressure and/or volume flow of the coolant in each of the spraying regions. The one or more partition walls divide the interior of the cooling bar into at least two chambers, each of the spraying regions being assigned to a different one of the chambers. The partition wall is shaped at least approximately in accordance with a temperature distribution along a width section of the metallic product before it enters the cooling device. The partition wall is arranged in the cooling bar over this width section.
