Paper Title:
Research on Surface Cracks of Thin Slab
  Abstract

This paper probes into the reasons about surface crack on the SS400 steel through analyzing FTSC. The results show that: the surface crack is mainly produced by the high content inclusion in SS400 steel and the fluctuation of inclusion makes the mould flux have bad performance. The protective slag is not filled fully which worsens the condition of heat transfer and makes the solidified shell uneven, thus it is easy to produce crack in the normal forces. Secondly , the slag entrapment and high content of sulfur is the another reason . There are a lot of calcium-aluminate ,silicates, sulfides which have high melting point and low plasticity in crack inside and around and their content gravely deviates from normal state. The effect of inclusion to crack is three times than the slag entrapment and just as the slag entrapment to high sulfur content
