Horizontal Sintering Furnace Door Heating for Uniform Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing horizontal sintering furnaces suffer from significant temperature differences between the ends and the middle portion, leading to inconsistent product quality due to the inability to adjust heating values at the ends in real time.
Innovation Solution
A novel furnace door heating apparatus with auxiliary heating bodies arranged in the Y-axis direction to independently control the temperature of the end regions, complementing the main heating body, which includes a circular arc structure with concave cavities facing the material bearing region and uniformly distributed heating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional main heating body is used without auxiliary heating bodies, then the structure is simple, but the temperature difference between the ends and middle portion of the furnace is significant
Solution Approach 1:
The heating apparatus is segmented into a main heating body and separate auxiliary heating bodies. The auxiliary heating bodies are positioned at the end regions and can be independently controlled, allowing localized temperature adjustment without complicating the overall main heating structure.
Solution Approach 2:
Different regions of the furnace are provided with different heating configurations. The auxiliary heating bodies are specifically placed at the end regions where temperature is lower, providing localized heating enhancement while the main heating body continues to handle the central region.
2Manufacturing precision
If the heating value at the two ends is not adjustable, then the control system is simple, but the product quality consistency deteriorates due to temperature difference
Solution Approach 1:
The temperature control system is segmented into independent control zones. Each auxiliary heating body has its own temperature control device, enabling independent adjustment of heating values at different end regions without affecting the main heating body or other regions.
Solution Approach 2:
The heating control system becomes dynamic and adaptable. The auxiliary heating bodies can adjust their heating values in real-time based on temperature feedback, allowing the system to respond to changing thermal conditions and maintain consistent product quality.
