Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed
into more functional shapes and sizes. While they have already been put in the furnace, they still require
a series of shaping and molding procedures such as hot and cold working, milling and cutting before they
are sold in hardware stores, or used for different applications. The unformed billets, however, can be used
in striking currency such as coins and as reserves, similar to gold bars.
Rectangular billet continuous casting billet and mainly general carbon steel, low carbon low silicon cold-rolled material, high quality carbon structural steel, high strength low alloy steel, special steel, etc.

- Q:What are the different types of surface defect detection methods for steel billets?
- Steel billets are subject to various methods of surface defect detection. Among the techniques commonly used are visual inspection, magnetic particle inspection, ultrasonic testing, eddy current testing, and laser scanning. 1. The simplest and most traditional method is visual inspection, where trained inspectors visually examine the surface of steel billets for cracks, scratches, or foreign material. 2. Magnetic Particle Inspection (MPI) is a non-destructive testing method that uses magnetic fields and iron particles to detect surface defects. The billet is magnetized, and iron particles are applied to the surface. Any defect causes a leakage of magnetic flux, attracting the iron particles and forming visible indications. 3. Ultrasonic Testing (UT) utilizes high-frequency sound waves to detect internal and surface defects in steel billets. Ultrasonic waves are emitted into the billet by a transducer, and the reflected waves are analyzed to identify flaws or irregularities. 4. Eddy Current Testing (ECT) makes use of electromagnetic induction to detect surface defects. A coil carrying an alternating current is placed near the billet's surface, generating eddy currents. Any variation in the surface, such as cracks or corrosion, alters the eddy currents, which are then detected by the instrument. 5. Laser Scanning is a relatively advanced method that employs laser technology to scan the surface of steel billets. The laser beam reflects off the surface, and a sensor analyzes the reflected light to identify surface defects like scratches or dents. These methods differ in terms of sensitivity, speed, and cost-effectiveness. The selection of the appropriate surface defect detection method depends on factors such as the required level of accuracy, the types of defects to be detected, and the specific requirements of the industry.
