In this paper, new technologies and new techniques in special steel rolling process at home and abroad in the nearly 10 years are analyzed and discussed. The rolling technologies of large size steel and high precision special steel are analyzed in rolling equipment aspect. The low temperature rolling technology, no heating forming technique and online heat treatment technology are discussed in terms of the rolling craft. The system integration technology of quality control and application technology being developed are analyzed in product quality control field. The ferrite deformation phase change, phase transition precipitation control, ultra-low temperature processing, nano-catalysts etc are analyzed and discussed in the quality control of technical progress. The trend of property controll for special steel is the application of integration techniques.
