钢包复合反射绝热层的试验

Compound Reflection Insulation Layer for Ladle

基于微纳米传热学理论,研制开发了钢包包壳内表面(1)氧乙炔火焰热喷涂纳米Al2O3涂层,(2)复合反射绝热板,(3)喷/抹涂绝热防护层,取得了钢包外壁温度下降78 140℃以上、减小钢水温降、提高内衬温度等效果.

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.
