PAC method, a new method measuring the porosity with concave in iron ore sinter, has been developed by applying a vacuum packing technology. PAC method is applicable to measure the total porosity of porous objects with an irregular shape such as iron ore sinter or sinter lump with a size of 10 to 100 mm. Porosity of commercial plant sinter measured by PAC method shows strong relativity to the reducibility (JIS-RI). Evaluation of total porosity by PAC method suggests directions for controlling the sinter reducibility. Furthermore, change of sinter porosity in handling process is detectable by PAC method. Porosity of sinter lump decreases propotionally to handling times along the process flow from sintering machine to blast furnace. PAC method provides significant data for process analysis and control.
