About steel, alloy; flat-rolled, width less than 600mm, of silicon-electrical steel, grain-oriented

HS code 722611 covers the classification of flat-rolled steel products that are less than 600mm in width, made of silicon-electrical steel, and have a grain-oriented structure. This specialized steel alloy is crucial for the manufacturing of high-efficiency electrical transformers, motors, and other electrical equipment. As a key component in the power generation and distribution infrastructure, the demand for grain-oriented silicon-electrical steel is closely tied to the growth and modernization of a country's electrical grid and industrial base.

Production process

The production of grain-oriented silicon-electrical steel involves a complex process of melting, casting, hot and cold rolling, and specialized heat treatments. The steel is first melted in an electric arc furnace or basic oxygen furnace, then cast into ingots or continuous cast into slabs. It is then hot-rolled to the desired thickness and width, followed by cold rolling to further refine the grain structure and improve the magnetic properties. The final step is a high-temperature annealing process that enhances the grain orientation and magnetic permeability of the steel.

Production inputs

The main inputs required for the production of HS code 722611 steel include high-purity iron ore, silicon, and other alloying elements such as aluminum and cobalt. Specialized rolling mills, annealing furnaces, and precision cutting equipment are also essential for the manufacturing process. Additionally, skilled metallurgists and engineers are needed to optimize the production parameters and ensure the consistent quality of the final product.

Production outputs

The primary output of HS code 722611 is grain-oriented silicon-electrical steel, which is primarily used in the manufacture of 850110 Electric motors and 850220 Transformers. This specialized steel is also consumed by producers of 850300 Parts of electric motors, generators, and transformers, as well as in the production of 850490 Parts of transformers, inductors, and static converters.
