摘　　要：为了更好地控制钢水浇注温度,保证钢水温度的稳定性,针对中间包隔热保温层和包壳防腐绝热涂层,以微观传热学为基础,研制开发了中间包包壳内表面氧乙炔火焰热喷涂纳米Al2O3涂层和粘贴复合反射绝热板的反射隔热保温技术,使中间包外壁温度下降了50～100℃,保证了钢水温度的稳定性,有利于控制钢水浇注温度。With regard to insulation layer and shell anti-corrosion insulation coating for tundish, the oxyacetylene flame hot spraying nanoscale Al_2O_3 coating and pasting compound reflection insulation plate for the inner surface of tundish shell were developed based on microscopic heat transfer theory. The results show that the temperature drop of 50-100 ℃ for outer wall of tundish is achieved and the molten steel temperature is stable, which is beneficial for the control of casting temperature.
