Abstract：Based on review of development about the processes of clean steel production at home and abroad, the technical principles and their necessities of low-cost and high-efficient clean steel production by combined blowing converter were analyzed, including low-temperature dephosphorization by combined blowing converter, the coordination of top and bottom blowing, the continuous implementation of the new process, the high-efficient oxygen blowing in decarburization period, and the reutilization method of slag been rich in P2O5, and so on. In order to obtain good implementation effect of the new process, the comprehensive and objective technical key points of the new process must be known well, and also the solid foundation of technical and management would be needed. According to related problems occurred in practice, the improved proposals were put forward.
