ABSTRACT:
This invention relates to ladle heating methods and apparatus. More particularly, this invention pertains to rapid high temperature ladle preheating utilizing an optimized heating cycle by involving oxygen and combustion air preheated by recuperation in the fuel burning process. Controlled oxygen flow directed into the process is used to increase the heat input during the initial preheating phase and to insure maximum efficiency of the system during the soaking phase of ladle preheating. The disclosed ladle preheating station comprises a refractory lined lid including a partially open refractory ring for docking a portion of a ladle rim having a significant protrusion caused by a local accumulation of solidified metal or slag, said refractory lid opening shaped to receive said protrusion within the opening while providing a gap between said metal deposition and the refractory lid. A burning device is located through said refractory lid for combusting fuel with air or oxygen or both and directing high temperature combustion products into the ladle interior. Also disclosed is a means for providing a protective facing for the ladle heater ring where it comes into contact with the ladle rim. The facing comprises stainless steel plates with a soft refractory material between said plates and the main refractory material of the ladle heater.
