Simulation study on heat transfer stress coupling model of the top wall of the 2250mm hot rolling line heating furnace
To reduce the heat loss on the surface of the hot rolling heating furnace,the use of nanomaterials can reduce the top temperature of the heating furnace,achieving energy-saving and consumption reduction effects.However,how to lay nanomaterials is a challenge.The geometric modeling of the heating furnace is established,which determines the thermodynamic boundary and mechanical boundary of the finite element calculation of the heating furnace.By analyzing the finite element calculation results of the heating furnace,the layering temperature change and stress change of the heating furnace are determined,which provides a numerical basis for the laying of nanomaterials.
