原理在工业加热炉的内壁涂上一层辐射率高的SiC涂料,将炉壁的黑度达到完全黑体的0.96,其目的是使炉子的辐射部接近完全辐射。工业用加热炉中,以燃料加热工件时辐射传热按玻耳兹曼式计算:式中T_1—散热面的绝对温度; T_2—受热面的绝对温度;
Principle The inner wall of the industrial furnace is coated with a high emissivity SiC coating to achieve a blackness of 0.96 in the furnace wall with the aim of bringing the radiant section of the furnace to near full radiation. Industrial furnace, the heating of the workpiece when the fuel radiated heat transfer by Boltzmann calculated: Where T_1-absolute temperature of the cooling surface; T_2-absolute temperature of the heating surface;
