The RG2 series roller type Cylinder-Type Electric Furnace outer covering is made the rectangle furnace body by the steel plate and the section. The furnace lining uses the ultra light quality high strength 0.6/cm3 micro bead energy conservation refractory brick, the heat preservation uses the entire high aluminum aluminum silicate textile fiber, belongs to the model ultra energy conservation structure. The resistance wire uses the 0Cr25Al5 high electric resistance alloy silk cord to become installs spiral-shaped, in the drum chamber puts on the silk brick, puts the silk brick to use our factory own production the acclivity 20° against to fall the silk brick, in resistance wire Yi Congcao does not drop out. The drum furance pot uses the 1Cr18Ni9Ti stainless steeliness full circle columnar order, or uses the chromium manganese nitrogen high-temperature steel casting, an origin bearing spider outside the furnace body the supporting, and uses the electric motor belt speed reducer to carry on the biography to use, to cause the furance pot to revolve slowly, the work piece causes it heating along with drum furance pot revolving to be even, and work piece mutually between non-cover phenomenon, after the heat treatment, the luster is consistent, furance pot another end is a feed head, by two hoop supporting. When feeding, leans on the furance supporting frame with the hand operated dynamic electricity furance the transmission gearbox handle, the drum furance upward incline, causes the feed head upward 20°, is advantageous for feeding, leaves when the material swings the incline downward 40°, then can actually draws a charge in the pot the work piece.
