Market Research and Development Trends of Oriented Silicon Steel Industry

图片
  Analysis and Forecast of Downstream Sub-market Applications in the Grain-Oriented Silicon Steel Industry China’s steel industry has entered a stage of fierce competition for existing market share. In 2023, crude steel production reached 1.005 billion tons, and steel product output reached 1.4 billion tons, representing a year-on-year increase of 1.1%. Driven by technological and industrial revolutions, the steel industry is accelerating structural upgrading and developing towards mid-to-high-end products. On the consumption side, demand for construction steel has declined, while demand for high-quality special steels such as medium and heavy plates, automotive steel sheets, and silicon steel has increased. High-end steel will become the main focus of future development, and grain-oriented silicon steel is expected to become a key development area for the steel industry. Analysis of the supply situation of my country’s grain-oriented silicon steel industry ...

CENTERSKY‘s Red Pomegranates

图片
  The October breeze swept through the pomegranate tree in front of the R&D center, its branches laden with fruit, their burnt-yellow, translucent red skins enveloping the glittering seeds. Light and shadow flickered beneath the tree, perfectly reflecting CENTERSKY ( EI LAMINATION ) ‘s flourishing glory. The story of this pomegranate tree dates back to 2003, the year CENTERSKY Electric moved into its brand-new factory. Mr. Xu, the general manager, said, “I hope that CENTERSKY will be like the pomegranate seeds, united and unyielding.” So, he planted a pomegranate tree, barely one meter tall, in the yard. In 2005, the tree bloomed for the first time. The vibrant orange-red petals, resplendent in the May sun, became a symbol of CENTERSKY’s early bloom. Time passed, and in 2020, when CENTERSKY ‘s new office building rose from the grounds, no one was willing to part with the old tree, a treasure trove of memories and companionship. So, workers carefully transplanted ...

Keeping going on the activity of Quality and Safety

图片
  As the scorching summer heat persisted, Jiangyin Centersky   Electric Appliance Co., Ltd, manufacture of EI lamination, organized the “Summer Cooling Aid, Care for the Frontline” event on June 27 to distribute heatstroke prevention and cooling kits to frontline operators. This initiative reflects the company’s commitment to the “people-oriented” corporate philosophy and conveys its deep care for employees. In hot weather, during the production of EI lamination , frontline employees stick to their posts to ensure production, which is the cornerstone of the company’s development. Distributing heatstroke prevention gift packages is not only a way to thank everyone for their hard work, but also an important measure for the company to strengthen its safety production defense line. At 11 noon, Manager Zhu from the Human Resources Department, as a representative, personally handed over the company’s carefully prepared heatstroke prevention gift packag...

Silicon Steel Laminations: Essential Components for Efficient Electrical Systems

图片
  Silicon steel laminations , also known as electrical steel laminations, are thin, flat sheets of low-carbon steel alloyed with silicon—typically 0.5% to 4.5% by weight. This unique composition grants them exceptional magnetic properties, making them indispensable in the production of electrical equipment that relies on electromagnetic induction. The addition of silicon is critical: it increases the material’s electrical resistivity, which minimizes eddy current losses— a major source of energy waste in magnetic devices. Moreover, silicon enhances magnetic permeability, allowing the material to efficiently conduct magnetic flux, and reduces hysteresis losses, which occur when the magnetic field reverses direction. Manufacturing silicon steel laminations involves precise processes. The steel is first rolled into thin sheets (usually 0.15mm to 0.5mm thick) through cold rolling, which aligns the metal’s crystalline structure (a process called grain orientati...

Silicon Steel Sheet: The Unsung Hero of Electrical Engineering

图片
  Silicon steel sheet , also known as electrical steel, is a specialized low-carbon steel alloy infused with 1% to 5% silicon. Designed primarily for magnetic applications, it stands out as a cornerstone material in modern electrical engineering, thanks to its unique combination of high magnetic permeability, low core loss, and excellent magnetic induction—traits that make it ideal for guiding and amplifying magnetic fields with minimal energy waste. Broadly, silicon steel sheets fall into two main categories: grain-oriented (GO) and non-grain-oriented (NGO). Grain-oriented sheets have their crystal grains aligned in a single direction during manufacturing, maximizing magnetic permeability along that axis. This makes them perfect for static magnetic devices like power transformers, where magnetic fields flow in a fixed path. Non-grain-oriented sheets, by contrast, have randomly oriented grains, ensuring uniform magnetic performance in all directions—ideal for rotating...

The Lamination Sheet EI Series: Essential Core for High-Efficiency Electromagnetic Equipment

图片
  The lamination sheet EI series stands as a cornerstone component in modern electromagnetic devices, widely utilized in transformers, inductors, and electric motors. Named for its iconic “E” and “I” shaped steel sheets, this series is engineered to optimize magnetic performance while minimizing energy loss, making it indispensable in power electronics and electrical engineering. Structurally, the EI series consists of two complementary sheet types: the “E” sheet (with three prongs forming a rectangular frame) and the “I” sheet (a flat rectangular strip). When assembled, these sheets interlock to form a closed magnetic circuit— a design that reduces magnetic flux leakage significantly. This modular structure also simplifies production and maintenance: manufacturers can easily stack, align, and secure the sheets without complex machining, cutting down on assembly time and costs. Material-wise, most EI lamination sheets are crafted from silicon steel (also ...
