钢铁工业的创新过程是以工艺创新为先导，以装备创新为核心，带动钢铁产品创新的持续创新过程。技术“S”曲线已经成为思考技术创新模式的核心工具。本文首先探讨炼铁工艺技术“S”曲线，然后描述炼钢工艺技术“S”曲线，最后论述“十一五”期间我国钢铁工艺技术创新模式。  

The iron &steel industry innovation process is characterized with taking the craft innovation as the forerunner, takingthe equipments innovation as the core and driving the steel &iron product innovationto continue innovation. TechnologyS-curve has become the core instrument for considering the technology innovation model. Firstly, theiron-making craft technology S-curve is elaborated, then the steel-making craft technologyS-curve is described, finally, the model of steel & iron process technology innovationin China during the period of the 11thfive-year plan is discussed. . 8 Refs In Chinese
