| Abstract: | Curving,flaw and scratching are often the three causes for strand to be judged as rejected. Problems in casting operation such as spray nozzle clogging in secondary cooling zone, slag deposit at foot roll and burrs in cutting operation were usually the main reasons to cause bloom defects. After those problems were overcome, bloom quality was improved remarkably. |
