Request PDF - Modeling of Continuous Casting Defects Related to Mold Fluid Flow - The quality of continuous-cast steel is greatly influenced by fluid flow.When it is necessary to minimize internal and surface defects, the casting speed is lowered (to allow impurities to float to the me- niscus in the mold), and in.Defects such as surface cracks can form here, if problems such as level fluctuations occur. To avoid this, oil or mold slag is added on top of the steel.Keywords: HSLA-Steel, Clean Steel, Continuous Casting, Hot Ductility, Surface Defects. Abstract. Continuous casting has been a primary process innovation in.Surface defects on continuously cast slabs require treatment by grinding.
