Furnace door shell is welded with steel plate and steel structure, inside lining is made of refractory fiber and inner refectory lining is made of steel fiber castables. Furnace door is drive by motor, reducer, transmission, chain, and the drive gear, 2 furnace door clamping cylinder connect the sealing blade on the furnace door with sealing ring (aluminum material fiber woven belt ), assuring furnace good air-tightness. End of the chain fixed with sprocket wheel, furnace door downward move depend on its deadweight. Movements of furnace door is controlled by PLC. Furnace Door and structure use water cooling structure, preventing deformation of the structure, effectively assuring hermetic, Furnace Door lifting speed: ~ 0.02m/s/0.16m / s. And furnace is equipped with ladder, maintenance table and maintenance platform and fence.
