The start-up of the DIOS pilot plant (DIOS Project)
The DIOS process has been successfully developed as an 8-year project commenced in April 1988. Based on the results of the element studies reported at the previous conference and at other meetings, the pilot plant, with a designed capacity of 500 t/d, was constructed and started up in october 1993. After the starting operation with the single smelting reduction furnace in the beginning of the first campaign, the pilot plant has been principally operated in integration, that is, with the smelting reduction furnace connected with the preheating and prereduction furnaces. So far five campaigns have been successfully conducted on schedule. The operation has been improved gradually and the designed performance has been achieved. New processes are targeted at the direct use of coal and iron ore fines to eliminate not only the problematic coke ovens but also pellet and sinter plants. The direct smelting reduction processes currently at the most advanced stage of development are the DIOS in Japan, the AISI in the USA and the HIsmelt in Australia.
