Cooling Beam Layout for Non-Uniform Metal Strip Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling apparatuses struggle to precisely adapt their cooling effect to non-linear temperature distributions across the width of metallic materials, often leading to overcooling at edges due to linear coolant distribution methods.
Innovation Solution
The cooling apparatus is designed with coolant application elements whose cross-sectional areas are distributed according to the slope of the temperature distribution, allowing for precise adaptation of cooling capacity by adjusting the density of outlet openings, even with constant coolant volume flow or pressure, by increasing gaps between nozzles where temperature decreases and increasing density where temperature rises.

Engineering Contradiction Analysis
1Device complexity
If linear coolant distribution is used across the cooling beam width, then the cooling apparatus structure is simple, but the cooling effect cannot precisely adapt to non-linear temperature distributions, leading to overcooling at edges
Solution Approach 1:
The patent applies local quality by varying the density of coolant application elements across the width of the cooling beam. Specifically, the outlet opening density is reduced in edge regions and increased in central regions, matching the non-linear temperature distribution pattern where edges are cooler than the center. This localized adaptation of coolant application density enables precise matching of cooling capacity to actual temperature profiles, preventing overcooling at edges while maintaining effective cooling in hotter central areas.
2Ease of manufacture
If constant density of outlet openings is used across the cooling beam width, then the manufacturing process is simplified, but the cooling capacity cannot be precisely adapted to progressive or degressive temperature curves
Solution Approach 1:
The patent implements parameter changes by systematically varying the density of outlet openings as a function of position across the cooling beam width. The outlet opening density is changed from constant to variable, specifically reducing density toward the edges and increasing it toward the center. This parameter variation enables the cooling apparatus to adapt to different temperature distribution patterns (progressive or degressive curves) while maintaining a relatively simple manufacturing process through standardized production of cooling beams with predetermined outlet patterns.

AI summary
A cooling apparatus for cooling a metallic material has at least one cooling beam with a plurality of coolant application elements for applying the metallic material with a coolant. In order to be able to adapt such known cooling apparatuses even more precisely to different temperature distributions across the width of the metallic material to be cooled the density of the cross-sectional areas of the outlet openings of the coolant application elements in the width direction y of the cooling beam be distributed or dimensioned according to the amount of the slope of the distribution of the temperature T(y) of the metallic material across its width before the inlet under the cooling beam. A method for cooling a metallic material so includes determining a temperature distribution of the metallic material to be cooled and producing or selecting a cooling beam to match the temperature distribution of the metallic material.
