摘要：

A kind of nanoporous thermal insulating material was applied in torpedo ladle to reduce the heat loss of molten iron during long term transportation in this paper. The nanoporous thermal insulating material with low thermal conductivity was prepared in the laboratory. In addition, a mathematical model based on simplified physics, material properties and heat balance of actual spot data was established to predict heat loss and temperature variation of molten iron during transport. The mathematical simulation results prove that the application of a thin insulation lining can significantly improve the thermal performance of the torpedo ladle.
