如何提高远红外元件的辐射强度,且使远红外元件主辐射频率与物体分子的固有频率尽可能相一致,这是应用远红外技术进行热处理的关键。但元件辐射强度与主辐射频率均与元件表面温度有关。电热元件辐射需要一定的能量,这就需要元件具有一定的温度。电热元件辐射的能量与电热元件温度的四次方成正比,即辐射元件表面温度降低一倍,总辐射能量就要减少十六倍。由此可见,电热元件表面温度对远红外炉的作用影响极大。远红外炉在达到预定炉温后断开电源,此时因电热元件温度远高于炉膛温度,元件表面温度将迅速地趋向于
How to improve the radiation intensity of the far-infrared component and make the main radiation frequency of the far-infrared component be consistent with the natural frequency of the object molecule as far as possible is the key to the heat treatment using the far-infrared technology. However, the component radiation intensity and the main radiation frequency are related to the component surface temperature. Heating element radiation requires a certain amount of energy, which requires components with a certain temperature. Heating element radiating energy and heating element temperature is proportional to the fourth power, that is, the radiation element surface temperature is doubled, the total radiant energy is reduced by 16 times. Thus, the heating element surface temperature far infrared furnace effect is greatly affected. Far-infrared furnace in the predetermined furnace temperature disconnect the power supply, this time because the heating element temperature is much higher than the furnace temperature, the element surface temperature will quickly tend to
