Research on the Application of Nanomaterials in the Insulation of Water Beams in Slab Reheating Furnaces
Aiming at the application of new nano thermal insulation materials in high temperature slab reheating furnace,a comparative study of the traditional water beam binding method and the new nano thermal insulation binding method is carried out.The thermal insulation effect and temperature distribution of different schemes are predicted through numerical simulation analysis,and the water cooling experimental system is built to test and analyze the heat dissipation of water beams with different binding methods.The test results show that as the furnace tempera-ture increases,the thermal conductivity of the fiber insulation material increases rapidly,and the heat dissipation of the conventional fiber in-sulation water beam increases rapidly.On the other hand,the thermal conductivity of the nano insulation material increases slightly,therefore the heat dissipation of the nano insulation water beam increases relatively slowly,and the difference in heat dissipation between the two schemes increases with the higher furnace temperature.On this basis,the engineering application is carried out,and the application effect is in good agreement with the numerical simulation and experimental research data.The comparison results of engineering applications show that the nano-insulated water beam can reduce the energy consumption of the water beam area by 25％compared with the traditional water beam bind-ing scheme,and has good economic and ecological benefits.
