PROBLEM TO BE SOLVED: To provide a method for surely measuring a shape of a refractory existing inside of a furnace even a furnace is large size, or the inside of the furnace is curved such as a U-shaped furnace.SOLUTION: The measurement method of inside of furnace refractory worn state for detecting a worn state of the refractory by measuring a surface shape of the refractory disposed inside of the furnace body comprises: measurement means 10 for measuring a two-dimensional shape in the furnace by radiating measurement light to the refractory. The measurement means 10 is moved by moving means in the furnace, and measurement is executed multi times, thereby a three-dimensional shape in the furnace is determined, and based on the three-dimensional shape, a worn state of the refractory is measured. |
