Analysis and controlling methods on transverse cracks of plate Nb containing steel slab

Journal Article


Abstract


  • For CC slab, because of many kinds of surface defects, steel sheets made up of such CC slab are usually refused. Among these defects, transverse cracks get main attention, Nb containing steel slab is easy to appear such cracks. Normally, in the bending segment and straightening period of vertical-bending continuous caster, surface and corner transverse cracks will appear in the inner face, corner transverse cracks will appear in the outer surface. The present paper analyzes the causes why the transverse cracks appear, through measuring temperature and High-temperature mechanical properties experiment, analyzing scheme of S355J2-1 steel secondary cooling water distribution, puts forward specific optimization measures, better results have been achieved.
