- Steel billets are a crucial component in the production of structural steel. These billets, which are essentially semi-finished steel products, serve as the starting point for the manufacturing process. The first step in making structural steel involves melting scrap steel in a furnace at extremely high temperatures. Once the steel has reached its liquid state, it is poured into molds to form billets. These molds are designed to shape the steel into a solid, rectangular shape with a consistent cross-section. Once the billets have solidified, they are then transferred to a rolling mill. Here, the billets are reheated to a specific temperature and passed through a series of rollers, which gradually reduce the billet's size and shape. This process is known as hot rolling and is essential for refining the steel's mechanical properties. The hot-rolled billets are then further processed through a variety of techniques such as forging, extrusion, or casting to create specific shapes and sizes required for structural applications. These techniques allow the billets to be transformed into beams, columns, plates, or other structural components. After the desired shape is achieved, the structural steel undergoes various treatments to enhance its strength, durability, and resistance to corrosion. This may include heat treatment, surface coating, or additional alloying elements. Finally, the finished structural steel products are used in a wide range of applications, including the construction of buildings, bridges, and infrastructure projects. The consistent size and shape of the steel billets ensure that the resulting structural steel components have the necessary strength, stability, and structural integrity to withstand the loads and stresses they will encounter in their designated roles. In summary, steel billets play a crucial role in the production of structural steel. They serve as the starting material, which is transformed through various processes into the desired shapes and sizes required for construction projects. The quality and consistency of the billets are essential in ensuring the strength and durability of the final structural steel products.

Visual Inspection: Skilled inspectors visually examine the billet's surface for any visible defects such as cracks, surface irregularities, seams, or abnormalities. This is the initial step to identify obvious defects that could impact the billet's quality. 2. Magnetic Particle Testing (MPT): MPT is a non-destructive testing method that utilizes magnetic fields and iron particles to detect surface and near-surface defects in steel billets. By magnetizing the billets and applying iron particles, any defects cause the particles to cluster, making them visible. 3. Ultrasonic Testing (UT): UT uses high-frequency sound waves to inspect the internal structure of steel billets. A probe transmits ultrasonic waves into the billet, and the reflected waves are analyzed to identify internal defects such as voids, inclusions, or cracks. 4. Eddy Current Testing (ECT): This technique uses electromagnetic induction to identify surface and subsurface defects. By creating eddy currents within the billet using a probe, disruptions caused by defects alter the electrical conductivity, which can be detected and analyzed. 5. Radiographic Testing (RT): RT involves the use of X-rays or gamma rays to inspect the internal structure of steel billets. The billets are exposed to radiation, and the resulting image is examined for internal defects such as cracks, voids, or inclusions. 6. Ultrasonic Phased Array Testing (PAUT): PAUT utilizes multiple ultrasonic beams to inspect the entire volume of the billet. By controlling the beam angle, frequency, and focus, this technique allows for better defect detection and sizing. These inspection methods are typically performed at various stages of the manufacturing process, both before and after the billets are heated, rolled, or further processed. By implementing these rigorous inspection techniques, manufacturers can identify and address defects early on, ensuring the quality and reliability of the steel billets.
