1.Structure of GI/CGI/SGCC Galvanized Steel Sheet In Coil
GI/CGI/SGCC Galvanized Steel Sheet In Coil is widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square metre.
Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.

- Q: How are steel strips used in the production of electrical transformers?
- Electrical transformers rely on steel strips as a vital component. These strips serve as the foundation for the transformer's core, which is responsible for transferring electrical energy between circuits. Typically composed of high-quality electrical steel, or silicon steel, these strips possess specific magnetic properties that make them ideal for transformer cores. With low core loss and high magnetic permeability, they facilitate efficient energy transfer. To construct the core, multiple steel strips are stacked together in a laminated structure. These laminations are tightly bound using insulating materials, which reduce eddy current losses and enhance transformer efficiency. By preventing electric current flow within the core, the insulating materials ensure that energy is directed to the intended circuit. The steel strips used in transformer cores also undergo annealing, a process involving controlled heating and gradual cooling. This process aligns the steel's magnetic domains, minimizing core losses and further improving transformer efficiency. In addition to their magnetic properties, steel strips contribute mechanical strength and stability to the transformer core. They preserve the core's overall shape and prevent deformation or damage during operation. Overall, steel strips play a critical role in the production of electrical transformers. They provide the core material with necessary magnetic properties, electrical insulation, and mechanical strength. Through their efficient design and construction, transformers operate reliably and efficiently, enabling the distribution and transmission of electrical energy.
- Q: How are steel strips processed for improved surface finish?
- Steel strips can be processed in various ways to achieve an improved surface finish. One common method is through the process of pickling and oiling. Pickling involves the immersion of steel strips in an acidic bath, such as hydrochloric acid, to remove any scales or impurities on the surface. This helps to create a clean and smooth surface. After pickling, the strips are rinsed and then coated with oil to prevent oxidation and improve the appearance of the surface. Another method used for improving the surface finish of steel strips is cold rolling. This involves passing the strips through a series of rollers at room temperature, which not only reduces the thickness but also enhances the surface finish. Cold rolling helps to create a more uniform and smooth surface, minimizing any imperfections or roughness. Furthermore, steel strips can undergo annealing to improve the surface finish. Annealing is a heat treatment process that involves heating the steel strips to a specific temperature and then slowly cooling them. This process helps to relieve internal stresses and improve the crystal structure of the steel, resulting in a refined and smoother surface. Additionally, steel strips can be subjected to various mechanical treatments, such as grinding or polishing, to further enhance the surface finish. Grinding involves the use of abrasive wheels or belts to remove any imperfections or roughness on the surface. Polishing, on the other hand, utilizes a fine abrasive material to create a smooth and shiny surface. In summary, steel strips can be processed for improved surface finish through methods such as pickling and oiling, cold rolling, annealing, and mechanical treatments like grinding and polishing. These processes help to remove impurities, reduce roughness, and create a clean and smooth surface, resulting in an enhanced appearance and performance of the steel strips.
- Q: How are steel strips stacked for storage?
- Steel strips are typically stacked horizontally on top of each other, with wooden or metal dunnage placed between each layer to provide stability and prevent damage. This stacking method ensures efficient use of space and allows for easy access and retrieval when needed.
