內容簡介We investigated the technology of various special optical filter combinations and found the optimum observation conditions at 800 - 1300°C to eliminate image distortion by heat and to observe joints and uneven surfaces of refractory linings. Because our special filter combination technology makes possible observations in high temperature conditions, we will apply it further to various commercial furnaces.
