【Abstract】 Abstract A new type of DC electric calcining furnace has been designed by Wuhan Iron & Steel Design & Research Institute in order to improve the calcining quality of the raw for producing carbon materials. The calcining temperature can reach 1700～2200℃. The furnace has several characteristics of simple constructure, easy operation and maintenance, less investment and low electricity consumption. Calcining anthracite with the furnace, the powder electric resistance is≤700μΩ·m and its real density is>1.84g/cm3, electric consumption≤800kW·h/t, The DC electric calcining furnace’s structure and using effect are introduced. It’s also given that what is the matter and how to deal with it.更多还原
