In this paper, it is studied the effects of main chemical elements P and Ti in ultra-low carbon deep drawing steel as well as main production technologies (i.e. cooling mode of hot rolling, annealing temperature and annealing speed) on strength of steel strip. The yield ratio of steel strip is reduced, punch formability is improved through optimizing the performances of DC04 of Baotou Steel according to customer requirements so that they could be met.
