These cracks can weaken the structural integrity of the billet and potentially cause breakage during subsequent processing. Central segregation is a defect that arises from an uneven distribution of elements within the billet. This uneven distribution leads to variations in composition across the billet's cross-section. As a result, the billet may possess inconsistent mechanical properties, making it unsuitable for certain applications. Inclusion defects occur when non-metallic particles or impurities become trapped within the billet during casting. These particles can originate from the refractory lining, mold powder, or the steelmaking process itself. Inclusion defects weaken the material and diminish its overall quality. Internal cracks are cracks that develop within the billet's body. Thermal stresses or improper cooling are often the culprits behind these cracks. Detecting internal cracks visually is challenging, and they can compromise the structural integrity of the billet. Surface and subsurface defects encompass various issues such as surface depressions, oscillation marks, and hot tears. Surface depressions arise from excessive mold oscillation or poor mold conditions. Oscillation marks result from non-uniform mold oscillation, leading to uneven cooling and inconsistent billet dimensions. Hot tears occur when the billet contracts unevenly during solidification, resulting in cracks on the surface or subsurface. Pipe defects are hollow cavities that form within the billet during solidification. Shrinkage is the main cause of these cavities, and they can weaken the material. If these pipes propagate to the surface, they can cause breakage during subsequent processing. Overall, these defects pose significant challenges in producing high-quality steel billets.
