Effects of the chemical components of slab (C, Mn, S, P, Ca, Cu, A1, Nb, V, Ti), the equipment and technologies of mold flux, tundish, mold and secondary cooling, etc. , on the occurrence of surface cracks in slab were reviewed. The evolution behavior of cracks during rolling was analyzed, which might be erased under some conditions through rolling processes. It is significant for understanding the influence factors on the surface cracks, and guiding the production for reducing the defects in products.
