Compound Reflection Insulation Layer for Ladle
钢包复合反射绝热层的试验

With regard to insulation layer and shell anti-corrosion insulation coating for ladle, oxyacetylene flame hot spraying nanometer Al2O3 coating (1), compound reflection insulation plate (2), spreading/putting insulationprotecting coating (3) for the inner surface of ladle shell were studied and developed based on microscale heat transfer. Temperature drop of over 78~140oC for outer wall of ladle, reduction of molten steel temperature drop and improvement of inner coating temperature were achieved.
