Abstract��Accurate controlling of end point was of important premise to ensuring the production reasonable and guaranteeing steel quality in steel plant. A general analysis of end point controlling process was analyzed from the aspect of characteristic of subsidiary material��s movement. With a particle swarm optimization PSO-based improved algorithm, an optimization control model for end point was established, and then an optimal controlling strategy was presented. The experimental results show the hit of the model with ��(��C)����0.03% is about 93.1% and with ��(��T)����12K is 94%, oxygen blowing time is shorted to 2.5 min, the subsidiary material savings of about 15%, the model achieved better optimization result.
