在电炉内涂敷碳化硅涂料剂的节能株洲工学院／黄汉云在热处理电炉内涂敷了自制的碳化硅涂料剂，发现升温时间缩短２／５，节能约８％。１．碳化硅涂料节能原理在工业炉内涂上辐射率高的涂料——碳化硅（ε＝０．９６）涂料剂，炉壁黑度接近于绝对黑体。因而炉衬向被加热物... Energy-saving coating of silicon carbide coating agent in the furnace Zhuzhou Institute of Technology / Huang Han Yun in the heat treatment furnace coated with a self-made silicon carbide coating agent and found that the heating time is shortened 2/5, energy saving of about 8%. 1. Silicon carbide coating energy-saving principle In the industrial furnace coated with high emissivity coating - silicon carbide (ε = 0.96) coating agent, furnace blackness close to the absolute black body. Therefore, the lining to be heated ...
