Q:What are the different types of steel billet surface defects?

During the manufacturing process, various steel billet surface defects may arise. These defects have the potential to impact the steel's quality and performance, thus necessitating their identification and resolution to safeguard the final product's integrity. 1. Scale: Oxidation during heating and rolling gives rise to a widespread defect known as scale. This defect manifests as a thin layer of iron oxide on the billet's surface, which can be readily eliminated through descaling procedures. 2. Cracks: Another common defect is cracks, which can emerge on the billet's surface. These cracks can be caused by factors such as uneven cooling, excessive stress, or improper handling. Due to their ability to compromise structural integrity, cracked billets necessitate repair or disposal. 3. Pitting: Pitting is characterized by shallow depressions or pits on the billet's surface. It can arise due to impurities in the steel, inadequate cooling, or corrosion. Pitting diminishes strength and heightens susceptibility to corrosion. 4. Lamination: Lamination defects occur when the billet experiences poor bonding during manufacturing, leading to the presence of layers or separation. This defect undermines the steel's mechanical properties, potentially resulting in failure under stress. 5. Inclusions: Non-metallic substances, such as slag, oxides, or other impurities, can become trapped within the billet during manufacturing, causing inclusions. Inclusions weaken the steel and decrease its ductility, rendering it more prone to cracking or breaking. 6. Scratches: Superficial defects like scratches may arise during billet handling or transportation. While they may not significantly impact overall structural integrity, they can concentrate stress in localized areas, potentially leading to failure in specific applications. 7. Decarburization: Decarburization occurs when the billet's surface loses its carbon content during the heating process. This defect reduces hardness and strength in the affected region, impacting the steel's performance. Manufacturers and inspectors must possess knowledge of these various steel billet surface defects to ensure the production of high-quality steel products. Regular inspections, quality control measures, and appropriate corrective actions are vital in minimizing and addressing these defects, thereby guaranteeing the desired steel performance and longevity.
