Melt-Holding Vessels TRIZ Cases
- Burner Oxygen-Concentration Control for Uniform Ladle Preheating
Gradually increasing oxygen in burner combustion helps preheat steelmaking ladles uniformly, limit refractory damage, and reduce carbon dioxide and NOx.
- Refractory Casting Nozzle Centering for Wobble-Free Changes
Centering elements and opposing bevellings guide refractory nozzles during replacement, preventing wobble and preserving coaxial alignment.
