Sliding Nozzle Apparatus Movable Frame Pressure Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding nozzle apparatuses are prone to damage when a surface pressure is loaded with no refractory plate mounted, due to incorrect operator actions or other errors.
Innovation Solution
The sliding nozzle apparatus is designed with a movable sliding metal frame that can switch between a first position where refractory plates are mounted for loading surface pressure, and a second position where no refractory plates are mounted, allowing surface pressure to be loaded between the fixed and sliding metal frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface pressure is loaded to the sliding metal frame in a state where no refractory plate is mounted, then the sliding metal frame and other components are likely to be damaged, but the apparatus needs to allow for maintenance operations requiring pressure loading without plates
Solution Approach 1:
The patent introduces a movable protective plate as an intermediary element between the pressure loading surface and the sliding metal frame components. This protective plate can be positioned to cover the pressure loading surface when refractory plates are not mounted, preventing direct pressure application to vulnerable components like hinge shafts and coupling shafts, while still allowing maintenance operations to proceed safely
Solution Approach 2:
The protective plate is designed to be positioned in advance before pressure loading occurs when no refractory plate is mounted. This beforehand cushioning prevents the harmful effect of direct pressure application to the sliding metal frame and its components, eliminating the damage risk while maintaining the ability to perform maintenance operations that require pressure loading without refractory plates
2Ease of repair
If the sliding metal frame is designed to allow pressure loading without refractory plates for maintenance, then ease of maintenance is improved, but the risk of component damage increases
Solution Approach 1:
The movable protective plate serves as a mediator that enables maintenance operations by allowing pressure loading without refractory plates, while simultaneously protecting the sliding metal frame components from damage through its positioning mechanism that covers vulnerable areas when needed
3Adaptability or versatility
If the apparatus allows flexible operation modes for both plate-mounted and plate-less pressure loading, then adaptability is improved, but the complexity of the apparatus increases
Solution Approach 1:
The protective plate is designed with movable positioning capability, allowing it to be dynamically positioned to cover the pressure loading surface when refractory plates are not mounted, or repositioned when refractory plates are installed. This dynamic adaptability provides operational flexibility for different maintenance scenarios without requiring multiple separate protective structures
Solution Approach 2:
The single movable protective plate serves multiple functions: it protects the sliding metal frame components from pressure damage during maintenance operations, and can be repositioned or removed to allow normal operation with refractory plates. This multi-functionality provides adaptability for both operational modes without significantly increasing apparatus complexity

AI summary
A sliding nozzle apparatus in which components constituting the sliding nozzle apparatus are less likely to be damaged even when a surface pressure is loaded with no refractory plate mounted. The sliding nozzle apparatus comprises a fixed metal frame and a sliding metal frame which is slidably provided with respect to the fixed metal frame. The sliding metal frame is movable between a first position where, in a state where two refractory plates are mounted, respectively, in a plate-receiving recess of the fixed metal frame and a plate-receiving recess of the sliding metal frame, a surface pressure can be loaded between the two refractory plates, and a second position where, in a state where no refractory plate is mounted to either plate-receiving recess, a surface pressure can be loaded between the fixed metal frame and the sliding metal frame.
