NOVELTY - A prepared graphene is a novel high warm reducing furnace pipe, a furnace tube main body, on the inner wall of the furnace tube main body coil welding has spiral conveying blade, and the border upon the spiral conveying blade set has a shovelling plate and a shovelling plate, a shovelling plate fixing installation b in the first wall surface of said furnace pipe the body cross section is V type, a shovelling plate fixed between the b of adjacent spiral conveying blade, the cross section is rhombus, and and a shovelling plate between the first exist, a shovelling plate and a shovelling plate a are along the furnace tube main body axial line is arranged. The utility model is new type can be a raw material oxidation graphene adequately mixed in a swing furnace furnace tube, oxidation by reducing graphene. complete completely, reducing efficiency is high, the same product is good, the production cost low.
