摘　　要：针对新型纳米绝热保温材料在高温板坯加热炉的应用,开展了传统水梁包扎方式与新型纳米隔热包扎方式的对比研究。通过数值仿真分析对不同方案隔热效果及温度分布进行了预测,并搭建水冷实验系统对采用不同包扎方式的水梁散热量进行测试分析。测试结果表明随着炉温逐步升高,纤维隔热材料的导热系数快速上升,常规纤维隔热水梁散热快速增加,而纳米隔热材料的导热系数增加较小,故此纳米隔热水梁的散热增加较为缓慢,两种方案散热量的差距随着炉温升高而逐渐增大。在此基础上开展了工程应用,应用效果与数值仿真及实验研究数据吻合良好。工程应用对比结果表明,纳米隔热水梁相对传统水梁包扎方案可实现水梁区域能耗降低25%,具有较好的经济和生态效益。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 temperature increases,the thermal conductivity of the fiber insulation material increases rapidly,and the heat dissipation of the conventional fiber insulation 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 binding scheme,and has good economic and ecological benefits.
