Abstract Center segregation and equiaxial crystal ratio are the important parameters to evaluate the quality of continuous casting slab. And the technologies of improving internal quality，such as electromagnetic stirring and micro-alloying technology，are complex relatively and high cost during implementation. In this study，steel strip was fed into the continuous casting mold，resulting in a lower superheat of molten steel due to the absorption of heat. This study also discussed the effect of steel strip weight on the quality of slab.. The results of calculation and experiment show that，the liquid steel superheat can be obviously reduced by steel strip feeding. The internal quality（osteoporosis，equiaxial crystal ratio etc.）of continuous casting slab with strip feeding is better than the one without strip feeding. And when the weight of the strip increases，the equiaxial crystal ratio increases，too. And the technology of strip feeding is helpful to improve internal quality of billet.
