Japan: According to Japan Metal Daily, the world's first space zero-gravity experiment using steel slag will start in Japan's current fiscal year. The experiment will try to suspend and melt steel slag in zero gravity to directly observe the interface between melt iron and slag. The interface between iron and slag, which is closely related to the steel refining efficiency, cannot be directly observed in earth experiments where crucibles are used. If successful, the basic research will provide highly accurate data on the interface, which are expected to advance high-purity steelmaking.
