Grain-oriented electrical steel is a special kind of steel with good orientation. It is used to manufacture large transformers and plays an important role in nuclear power plants. In this article we will explore the use of grain-oriented electrical steel in nuclear power plants and its impact on transformer performance.

The 20-roll rolling mill is a key equipment for manufacturing high magnetic induction and low loss oriented electrical steel. This article will provide an in-depth analysis of the working principle and manufacturing process of the 20-high rolling mill, and explore its impact on the quality of electrical steel. We will introduce the 20-high rolling mill from multiple angles to provide readers with a comprehensive and in-depth understanding.

Grain-oriented silicon steel: Grain-oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in the transformer (core) manufacturing industry.

Non-oriented silicon steel: Non-oriented silicon steel is a ferrosilicon alloy with very low carbon content. Its grains are randomly oriented in the deformed and annealed steel plate.

Electrical steel is a ferromagnetic material made up of iron that contains varying amounts of silicon (Si) that range from 1% to 6.5%. The development of electrical steels was brought on by electrical devices requiring steels that can decrease the dissipation of heat, an issue that results in energy wastage.

A special electrical steel that does not have a distinct grain orientation.

It has low hysteresis, low loss and high permeability.

Widely used in transformer, motor and power generation equipment and other fields.

Non-oriented electrical steel (NOES) has high permeability, high magnetization saturation, low core loss, and relatively low cost.The magnetic properties of non-oriented electrical steels strongly depend on the silicon content, the cleanliness of the steel, the thickness of the steel sheet, and the grain size and texture of the final lamination.

Silicon steel, an essential soft magnetic material, has established itself as a key player in contemporary industrial applications. Ranging from small-scale operations in relays and pulse transformers to large-scale use in generators, motors, and transformers, silicon steel continues to grow in importance. Its adoption has been driven by the need for more efficient energy use and the miniaturization of powerful equipment.

The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel.

With the adjustment of China's steel industry structure, there are dozens of kinds of steel products launched in the world this year, and these high-end products not only meet the needs of domestic manufacturing industry, but also become popular products exported overseas.
