| Abstract: | In this paper, the present status and neal developed DR processes abroad andin China were presented. It is collcluded from the analysis of the natureal resources distribution and the specific R&D conditions in our countly that it is the main trend for China to accelerate the coal --based rotary kiln DR processes should be developed to deal with lowgrade ores. Such are important methods to promote the production of steel of good quanlityby DR/EAF. |
