PURPOSE: A viscometer of molten slag is provided which shortens viscosity measuring time, improves reliability on viscosity measurement and prevents decarburization of a carbon measuring cup and a carbon rotor so that the carbon measuring cup and the carbon rotor can be reused. CONSTITUTION: In a viscometer of molten slag in which a carbon measuring cup(10) is received inside an electric furnace tube(24) and supported by a pedestal at the lower part of the electric furnace tube(24), a flat plate is coupled to the lower part of the pedestal so that the flat plate is vertically moved by a certain drive means, a support axis is fixed to the side surface of the electric furnace in such a manner that a cooling means, a drive means and a sensing means are fixed to the upper part of the support axis, and a carbon rotor is mounted on the end part of the drive and sensing means, the viscometer of molten slag comprises inert gas supply pipes(16a) which are positioned on the inner wall of the tube and vertically extended to the lower part of the carbon measuring cup; a reflection mirror(44) which is adhered to the lower part of the cooling means vertically corresponding to the upper surface of the tube; and an indicator(42) which is adhered to the lower part of the cooling means, wherein a reference point corresponding to the indicator is marked on the electric furnace, and the inert gas supply pipes(16a) are fixed onto the outer circumferential surface of the carbon measuring cup(10) with spaced apart from each other in the same distance.
