Abstract：Due to the free- heating direct rolling process of continuous casting billet without the heating furnace, the energy and cost were saved and the emission was reduced compared with the conventional continuous casting- rolling process. The characteristics and key technologies of the free- heating direct rolling process were introduced, and the application of the narrow window control in the direct rolling process was analyzed. According to the improvement of the need for the product quality, the big data- driven direct rolling narrow window control technology was expected to emerge. With this technology, the lagging of the temperature and composition control system in the steel smelting- continuous casting- direct rolling process can be solved, which could be a revolutionary change to China’s steel industry.
