The industry trend toward the use of high alumina and dolomite refractories in steel ladles coupled with longer holding times, has prompted the investigation of incorporating insulation into the refractory lining. Benefits of insulating steel ladles are: reduction in steel temperature loss over extended time, protection for the ladle shell, increased refractory life, reduced scrap and skulling, and enhanced or minimized preheating. One type of insulation is discussed that combines high strength, low thermal conductivity and nominal thickness. Its success in reducing temperature loss in iron ladles led to its use as steel ladle insulation. Case histories are discussed in addition to installation techniques and perceived benefits of the insulating board. Ladle shell protection, increased refractory life, and enhanced ladle preheat are emphasized more than reduction in steel temperature loss.
