Solution Overview
Problem
The production of converter drainage systems for metallurgical equipment is complex and costly due to the complexity of cooling tubes, which also complicates welding and maintenance, especially with non-constant distances between adjacent tubes and limited accessibility for inspection.
Innovation Solution
A coolant guide unit with a leading pipeline and a fluid-conductive return tube line, featuring parallel longitudinal portions and obliquely aligned intermediate portions for interconnection, allowing for cost-effective production and high-quality welding, along with improved accessibility for inspection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional cooling pipes with non-constant distance between return sections are used, then the converter exhaust hood can be constructed, but the welding complexity increases and weld inspection becomes difficult
Solution Approach 1:
The cooling pipe is divided into separate supply section and return section that can be manufactured independently and then assembled through welding, allowing each section to be optimized separately for manufacturing and welding processes
Solution Approach 2:
The supply section and return section are designed with different geometries optimized for their specific functions, with the return section having a constant distance configuration that simplifies welding compared to the traditional symmetric design
2Ease of manufacture
If traditional cooling pipes with complex shapes are used, then the cooling function is achieved, but the cost of manufacture increases
Solution Approach 1:
Dividing the cooling pipe into modular supply and return sections enables standardized manufacturing processes and reduces fabrication costs compared to producing complex monolithic pipes
Solution Approach 2:
Instead of creating a complex single-piece pipe structure, the invention inverts the approach by using separate simple sections connected through welding, reducing overall manufacturing complexity and cost
3Ease of operation
If traditional double-walled structure with welded cooling pipes is used, then the cooling function is provided, but accessibility for inspection and maintenance is limited
Solution Approach 1:
The modular design with separate supply and return sections that can be accessed independently improves inspection and maintenance accessibility compared to traditional enclosed double-walled structures
