The iron loss of electrical steel plate is divided into eddy current iron loss and hysteresis iron loss. Eddy current iron loss is the iron loss caused by the induced current flowing in the transformer core in AC magnetic field.

At present, the most commonly used material for motor core is cold-rolled laminated steel, which is the lowest cost material for batch applications, and easy stamping and low tool wear help reduce the cost of finished lamination.

The first is strong corrosion resistance, the chromium element in the stainless steel tube can react with oxygen to form a dense chromium oxide film to prevent further oxidation reaction, thus having good corrosion resistance. Therefore, stainless steel pipes are widely used in corrosive environments such as humidity and acid and alkali.

Electrical steel core loss (referred to as iron loss) and magnetic induction strength (referred to as magnetic induction) as the product magnetic guarantee value. The low loss of electrical steel can save a lot of electricity, extend the operating time of motors and transformers and simplify the cooling system.

Electrical steel pipe, also known as electrical silicon steel pipe, is a special cold-rolled steel. It is mainly made of electrical steel strip through cutting, winding and welding processes.

This defect is caused by the inability to cut off the hot rolled coil and flow down to the electrical steel sheet factory, so its cause is the same as the cause of scarring on the raw material hot rolled plate.

In terms of domestic demand, China's economic development is still facing the triple pressure of shrinking demand, supply shock and weakening expectations. Therefore, in 2023, China's economic work will still be based on "stability", focusing on "stable growth, stable employment and stable prices".

In recent years, due to the promotion of the national carbon neutral and carbon peak dual-carbon policy and the explosive growth of the new energy automobile industry, the potential demand for high grade and new energy grade electrical steel has increased significantly, and non-oriented electrical steel manufacturers have laid out new energy grade products and increased the production capacity of high grade products.
