1.新型高辐射电阻带式节能炉根据电加热炉辐射传热机理,强化了电热元件与工件的辐射传热过程,有效地提高了炉膛和工件的升温速度,减少了炉壁蓄热和散热损失,提高了炉子的热效率。高辐射率涂料在加热过程中通常起两个作用:①提高辐射强度;②改变辐射能谱分布ελr、(ελr是涂层的单色辐射率,E_(λο)是该温度时的黑体 1. The new high radiant resistance band energy-saving furnace according to the electric heating furnace radiation heat transfer mechanism, and strengthen the heating element and the workpiece radiation heat transfer process, effectively raising the furnace and workpiece heating rate, reducing the furnace wall heat storage and cooling Loss increases the thermal efficiency of the furnace. High emissivity coating usually plays two roles in the heating process: (1) to increase the radiation intensity; (2) to change the radiant energy distribution ελr, (ελr is the monochromatic emissivity of the coating, E_ (λο)
