PURPOSE: To provide a device for correcting position of muffle in bright annealing furnace, wherein the device is capable of maintaining a uniform gap between the muffle and the heating furnace by detecting a gap between the muffle and the heating furnace when initially inserting the muffle into a heating furnace, thereby adjusting position of the muffle. CONSTITUTION: The device for correcting position of muffle in bright annealing furnace comprises detection parts installed on a lower part of a heating furnace(7) of the bright annealing furnace with being spaced apart from each other to check a gap between the inner wall of the heating furnace and the muffle; and an adjustment part comprising step motors(30) that are installed along an upper part of the heating furnace with being spaced apart from each other in a certain distance and rotated forward and reversely according to signals of the detection parts, gear boxes(31) connected to rotary shafts of the step motors to convert rotary power of the step motors into vertical directional straight moving power, and driving rods(32) installed on the gear boxes, vertically moved and projected upward such that upper flanges(6) of the muffles are put on the driving rods, wherein the adjustment part adjusts slope of the muffles.
