| Abstract: | The present status and challenges of blast furnace ironmaking technology are analyzed， and the developing objectives of the contemporary BF ironmaking process are mentioned. The significance and function of high blast temperature and oxygen enriched-pulverized coal injection for BF ironmaking are described. The key technologies of high blast temperature and oxygen enriched-PCI are discussed and evaluated emphatically. Promoting blast temperature and improving oxygen enrichment ratio， as well as enhancing PCI rate are important guarantee for saving fuel consumption， re- ducing operation cost， and realizing sustainable development. There are broad developing prospects of contemporary BF process under the condition of high blast temperature and low fuel ratio in ironmaking technologies. |
