Where are electrical steel sheet factories typically located in China?
Electrical steel sheet factories in China are often located in industrial zones and economic development areas. For example, Shanghai JISCO Electrical Technology Co., Ltd. is based in Shanghai Baoshan, while Cibao New Sheet Metal (Jiangsu) Co., Ltd. is situated in the Haimen Economic and Technological Development Zone in Jiangsu Province. These locations are chosen for their proximity to raw materials, transportation hubs, and skilled labor.
What types of electrical steel do these factories produce?
Chinese electrical steel sheet factories produce a variety of products, including oriented and non-oriented electrical steel. Oriented electrical steel, also known as grain-oriented electrical steel, is used in transformers, rectifiers, and large motors due to its high magnetic induction and low core loss. Non-oriented electrical steel is used in smaller motors and other electrical devices. These factories also produce high-end home appliance galvanized sheets.
What is the manufacturing process for electrical steel sheets?
The manufacturing process involves several steps. It starts with reheating and hot-rolling a steel slab to produce a hot-rolled steel sheet. The sheet is then annealed, cold-rolled to adjust the thickness, and undergoes decarburization annealing. Finally, it is finish-annealed for secondary recrystallization to achieve the desired magnetic properties. Some processes also include coating the steel sheet with a powder coating agent for siliconization.
How do these factories ensure quality and compliance with international standards?
To ensure quality, these factories often undergo third-party audits to confirm their ability to manufacture products to high standards. They also adhere to strict quality control measures, including advanced inspection and testing equipment. Additionally, they may produce audit documents necessary for working with big retailers and meeting the requirements of various international markets.
What are the typical applications of electrical steel sheets produced in these factories?
Electrical steel sheets produced in these factories are widely used in various industries. They are essential for making iron cores for transformers, rectifiers, reactors, and large motors. These sheets are also used in nuclear power plants, hydropower stations, and military projects. The high-magnetic induction and low-loss properties of these sheets make them indispensable in the power, electronics, and military industries.
