HS v2017 Code: 722611

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 type of steel is highly valued for its magnetic properties, making it a crucial component in the production of electrical transformers, motors, and other electrical equipment. As a specialized steel product, 722611 plays a significant role in the broader electrical and electronics industries, contributing to the efficient generation, transmission, and utilization of electrical power.

Production process

The production of grain-oriented silicon-electrical steel (722611) involves a series of complex processes. First, the steel is melted and cast into ingots or continuous cast slabs. These are then hot-rolled to the desired thickness and width, followed by a series of cold-rolling and annealing steps to achieve the desired magnetic properties. The final stage involves a specialized process called 'domain refining,' which aligns the grain structure of the steel to enhance its magnetic permeability and reduce energy losses.

Production inputs

The main inputs required for the production of HS code 722611 steel include high-purity iron, silicon, and other alloying elements such as aluminum and manganese. Specialized rolling mills, annealing furnaces, and domain refining equipment are also essential for the manufacturing process. Additionally, skilled technicians and engineers are needed to operate and maintain the production equipment, as well as to monitor and control the various stages of the manufacturing process.

Production outputs

The primary output of HS code 722611 is grain-oriented silicon-electrical steel, which is used extensively in the production of 851110 Transformers, 850161 AC motors, and other electrical equipment. This specialized steel is valued for its superior magnetic properties, which contribute to the efficiency and performance of these devices. The output of 722611 may also be consumed by manufacturers of 850300 Parts of electric motors, generators, and rotary converters and 853710 Boards, panels, consoles, desks, cabinets, and other bases for electric control or the distribution of electricity.
