摘      要：Hypo-peritectic steels are widely used in various industrial fields because of their high strength,high toughness,high processability,high weldability,and low material ***,surface defects are liable to occur during continuous casting,which includes depression,longitudinal cracks,deep oscillation marks,and severe level fluctuation with slag *** high-efficiency production of hypo-peritectic steels by continuous casting is still a great challenge due to the limited understanding of the mechanism of peritectic *** work reviews the definition and classification of hypo-peritectic steels and introduces the formation tendency of common surface defects related to peritectic *** achievements in the mechanism of peritectic reaction and transformation have been ***,countermeasures to avoiding surface defects of hypo-peritectic steels duiring continuous casting are *** certain points in the continuous casting of hypo-peritectic steels and the development of new techniques to overcome the present problems will be a great aid to researchers.
