Abstract：Shougang Jingtang United Iron and Steel plant is constructed based on the new generation steel manufacturing process. The design concept is dynamic-orderly and coordinated consistent. With the optimization of the art of BF tapping and the system development of BF tapping-KR pretreatment connecting interface,the intelligent control is accomplished. Combined with the special line and fast rhythm production and BOF low-temperature tapping technology and supplemented with the slab yard optimization and casting-rolling integration,the clean steel production with high efficiency and low cost is achieved. The result shows that the constructer of briefness and smooth process network is the basis for high efficiency material flow and the least dissipation of energy flow and also the implement of the overall throughout of information flow. Advanced hot metal pretreatment,converter end-point control,secondary refining and high-speed casting are supportive technologies to construct the clean steel production platform. In addition,the special line production is the most effective way.
