Defects Analysis and Control Measures of Continuous Casting Product

Quality defects such as edge crack,roll,strip edge uplift,oxide scale indentation usually occurred in the strip produced in a 1700 hot strip line.In order to eliminate these defects,the main morphology characteristics and causes were analyzed.A series of measures had been taken through adjustment,optimization and transformation for the caster mold taper,work roll gap,laminar cooling side spray and curl side guides machine,phosphorus removal systems and so on.All these efforts effectively reduced the incidence of defects and improved product quality and the product yield.
