To enhance the surface roughness of steel billets, there are various surface treatments available. These treatments aim to improve the quality and properties of the billets, making them more suitable for different industrial applications. Some commonly used surface treatments for achieving better surface roughness in steel billets are as follows:
1. Shot Blasting: In shot blasting, high-speed abrasive particles are used to bombard the surface of the steel billets. This treatment effectively removes any contaminants, scale, or unevenness present on the surface, resulting in a smoother and more uniform finish.
2. Acid Pickling: Acid pickling involves immersing the steel billets in an acid solution, typically hydrochloric or sulfuric acid. This chemical treatment dissolves any oxides, rust, or scale present on the surface, leaving behind a clean and smoother surface.
3. Mechanical Grinding: Mechanical grinding employs abrasive wheels or belts to remove material from the surface of the steel billets. This treatment is particularly effective in eliminating deep scratches, pits, or irregularities, resulting in a smoother and more polished surface.
4. Electrochemical Polishing: Electrochemical polishing is an electrochemical process that combines chemicals and electrical current to remove a thin layer of material from the steel billet's surface. This treatment helps eliminate any surface imperfections, resulting in a smoother and more reflective finish.
5. Roller Leveling: Roller leveling involves passing the steel billets through a set of rollers that exert pressure on the surface, flattening and smoothing out any irregularities. This treatment is especially effective in improving the flatness and surface roughness of the billets.
6. Thermal Treatment: Thermal treatment, such as annealing, can also enhance the surface roughness of steel billets. Annealing involves heating the billets to a specific temperature and slowly cooling them to relieve internal stresses and improve the surface finish.
It is crucial to consider the specific requirements of the steel billets and the desired surface roughness when selecting a surface treatment. Each treatment has its advantages and limitations, and factors such as the type of steel, dimensions of the billets, desired surface finish, and cost-effectiveness should be taken into account when choosing the most suitable treatment.

There are several surface treatments that can be used to improve surface roughness in steel billets. Some common methods include shot blasting, pickling, and mechanical polishing. Shot blasting involves propelling abrasive particles at high speeds onto the steel surface to remove any impurities and create a smoother finish. Pickling involves immersing the steel billets in an acid solution to remove oxides and scale, resulting in a cleaner and smoother surface. Mechanical polishing uses abrasive materials and tools to physically remove any imperfections and create a smoother surface. These treatments can significantly enhance the surface quality of steel billets, making them suitable for various applications.
