Beveled Refractory Closure Plate for Sliding Spout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding closures on molten metal containers, particularly converters, face rapid wear of refractory parts due to direct contact and dimensional mismatches, necessitating frequent replacements and potential damage during bracing and adjustment.
Innovation Solution
A closure plate with beveled surfaces on refractory plates to reduce damage during bracing and adjustment, featuring a multi-part refractory plate with a metal jacket, and a cassette system allowing for easy replacement of worn plates without dismantling the housing frame, incorporating bevels to mitigate edge contact and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If closure plates with flat sliding surfaces are used for bracing, then the structure is simple, but damage occurs to end faces during bracing and adjustment due to dimensional mismatches and edge contact
Solution Approach 1:
The invention applies beveled surfaces (inclined planes) instead of flat surfaces at the bracing interfaces of closure plates. This curvature/angle modification allows gradual contact during bracing operations, distributing forces across the surface rather than concentrating them at edges, thereby preventing damage while maintaining manufacturing feasibility.
2Ease of repair
If worn base plates are replaced by dismantling the housing frame, then replacement is possible, but productivity is reduced due to frequent interruptions in casting operation
Solution Approach 1:
The invention segments the base plate from the housing frame by providing detachable connection means. This allows the base plate to be replaced independently without dismantling the entire housing frame, enabling quick replacement of worn plates while maintaining casting operation continuity and improving productivity.
3Ease of repair
If multiple closure plates are stored in the housing frame for replacement, then replacement ease is improved, but device complexity increases due to additional storage mechanisms
Solution Approach 1:
The housing frame is designed with universal features that serve multiple functions: it provides structural support, contains detachable connection means for base plates, and incorporates storage spaces for multiple replacement base plates. This multi-functionality allows easy replacement operations without requiring additional complex storage mechanisms, thereby avoiding increased device complexity.

AI summary
A closing plate for a sliding closure on the spout of a receptacle for molten metal, especially of a converter, comprises an elongate refractory plate (11) and a sheet metal jacket (12) surrounding the same. The refractory plate (11) has a sliding surface (14, 16) which can be braced with a sliding surface of a refractory closure plate interacting therewith or with a sliding surface (21') of a refractory head part (21). The refractory plate (11) has a tapering section (26, 28, 29) which forms an angle (a) with the sliding surface (14, 15) on at least one side delimiting the sliding surface (14, 15), said tapering section being associated with a section of the refractory plate (11) that projects beyond the sheet metal jacket (12). The closing plate according to the invention allows the risk of damage to the front faces of the refractory parts to be braced with each other to be substantially reduced during bracing of the parts with each other and/or during a relative adjustment of the refractory parts that are braced with each other.
