Furnace Chamber Layout for Stable Temperature-Maintained Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furnaces experience significant temperature variations in the temperature-maintained space due to atmospheric disturbances, leading to variations in the heating amount on treatment objects.
Innovation Solution
The furnace design includes a temperature-maintained space with a larger cross-sectional area compared to the preheating space, along with controlled atmospheric gas flow to minimize disturbances, ensuring consistent temperature maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the cross-sectional area of the temperature-maintained space is made smaller than the preheating space, then the furnace structure is more compact, but temperature variation in the temperature-maintained space increases due to atmospheric disturbances
Solution Approach 1:
The patent inverts the conventional furnace design by making the cross-sectional area of the temperature-maintained space larger than that of the preheating space. This inversion resolves the technical contradiction by creating a larger thermal mass in the temperature-maintained space, which stabilizes temperature and reduces variation caused by atmospheric disturbances, while accepting a less compact overall structure.
2Stability of the object's composition
If the cross-sectional area of the temperature-maintained space is increased, then temperature stability improves, but the furnace becomes less compact and larger in size
Solution Approach 1:
The patent changes the geometric parameter of the furnace cross-sectional area along its length, specifically making the temperature-maintained space have a larger cross-sectional area than the preheating space. This parameter change increases the volume of atmospheric gas in the temperature-maintained space, thereby improving temperature stability and reducing the impact of atmospheric disturbances.
3Area of stationary object
If the cross-sectional area of the temperature-maintained space is made smaller, then the furnace is more compact, but the heating amount on treatment objects varies due to atmospheric disturbances
Solution Approach 1:
The patent inverts the conventional design approach by enlarging the cross-sectional area of the temperature-maintained space relative to the preheating space. This inversion increases the thermal mass and atmospheric gas volume in the temperature-maintained space, which stabilizes the heating environment and ensures consistent heating amount on treatment objects, despite the increased furnace size.

Function Achieved in This Case
This configuration reduces temperature variations in the temperature-maintained space, thereby stabilizing the heating amount on treatment objects.
Implementation Method 1
a cross-sectional area of the temperature-maintained space is greater than a cross-sectional area of the preheating space... variation caused by disturbance in the atmosphere in the temperature-maintained space is small, resulting in less variation in the temperature

AI summary
A furnace configured to heat a treatment object is provided, and the furnace may include: a furnace body including an entrance, an exit, and an internal space extending in a conveying direction from the entrance to the exit; and a conveying device having a conveying surface which carries the object thereon and conveys the object in the conveying direction. The internal space may include: a preheating space communicated with the entrance and which preheats the object; a temperature-maintained space communicated with the preheating space and which heats the object, wherein a temperature in the temperature-maintained space is maintained constant; and a cooling space communicated with the temperature-maintained space and the exit and which cools the object. When the furnace body is cut along a plane perpendicular to the conveying direction, a cross-sectional area of the temperature-maintained space may be greater than a cross-sectional area of the preheating space.
