摘　　要：基于微尺度传热学 ,从气体分子热运动、热传导、热辐射方面 ,分析了物质的热量传输规律对尺度的依赖性。针对钢包、中间包采用的隔热保温 ,研究和开发纳米绝热材料和绝热结构的复合反射绝热层 ,使包壳外壁温度和钢水温降率明显减小 ,有利于钢包、中间包的扩容 ,有利于钢水保温和浇注温度控制 。Based on microscale heat conduction theory, the dependency of heat transfer law of substance on dimension is analyzed in the respect of gas molecular heat kinetic, heat conduction and heat radiation With regard to maintaining temperature by insulation for ladle and tundish, compound reflection insulation layer with nanometer insulation material and insulation structure is studied and developed, which decreases temperature drop for outer wall and molten steel temperature drop rate, enlarges in volume of ladle and tundish and helps to control casting temperature It is significant in promotion of applying on engineering
