Electrical steel is categorized into 2 main kinds: grain-oriented (GO) and non-grain-oriented (NGO) electrical steels. Each type has distinctive properties and applications, customized to satisfy certain demands in electromagnetic gadgets.
1. Grain-Oriented (GO) Electrical Steel
Grain-oriented electrical steel is identified by its lined-up grain frameworks, which dramatically enhance its magnetic properties. The grains are carefully set up throughout the production process to accomplish high magnetic leaks in the structure and reduced core loss. These qualities make GO electrical steel specifically suitable for use in transformers and other tools where effective magnetic flux control is crucial.
The thorough positioning of grains in GO steel ensures that the product shows exceptional efficiency towards rolling, which is crucial for applications requiring marginal energy loss and high effectiveness.

The production of electrical steels is a thorough process that includes numerous crucial stages, including high-temperature rolling, acid pickling, and cold rolling. Each of these actions is crucial to achieving the desired thickness and improving the magnetic properties of the steel.
1. High-Temperature Rolling
In the initial stage, steel slabs are heated and rolled to lower their thicknesses. This process, referred to as hot rolling, is vital for breaking down the actors’ structure and acquiring a rough shape. The rolling temperature levels generally vary between 1100 ° C to 1300 ° C, which facilitates the formation of a polished grain framework.
2. Acid Pickling
After hot rolling, the steel goes through an acid pickling procedure to eliminate surface oxides and pollutants. Marinading entails engaging the steel in a bathroom of hydrochloric or sulfuric acid, which cleans the surface and prepares it for further processing. This step is important to ensure a smooth and tidy surface for subsequent cold rolling.
3. Cold Rolling
The cold rolling phase follows pickling, where the steel is further minimized to the final desired thickness at room temperature. Cold rolling not only fine-tunes the thickness but also enhances the surface finish and mechanical buildings of the steel. This process is vital for attaining the precise measurements and premium surface required for electrical steels.
4. Grain-Oriented Electrical Steel Processing
For grain-oriented (GO) electrical steels, extra processing actions are needed to regulate the crystal positioning. The goal is to align the grains in a particular direction to enhance magnetic leaks in the structure and decrease core loss. This includes a secondary annealing procedure, understood as high-temperature annealing, where the steel is heated up to temperatures around 800 ° C to 1200 ° C. During this stage, the grains are recrystallized and aligned to enhance their magnetic properties.
| Steps | Temperature Range | Objective |
| High-Temperature Rolling | 1100 ° C to 1300 ° C | Lower thickness, fine-tune grain framework |
| Acid Pickling | Room Temperature | Remove oxides and contaminations |
| Cold Rolling | Room Temperature | Accomplish final thickness, enhance surface finish |
| High-Temperature Annealing (GO Steel) | 800 ° C to 1200 ° C | Straighten grain orientation, enhance magnetic properties |
5. Non-Grain-Oriented Steel Processing
For non-grain-oriented (NGO) electrical steels, the grain framework is random, and the processing actions concentrate on attaining uniform properties throughout the product. Cold rolling and annealing are carried out to fine-tune the grain size and improve the magnetic properties without specific grain positioning. This makes NGO steels extra flexible and cost-efficient for numerous applications such as motors and generators.
The manufacturing procedure of electrical steels, therefore, needs cautious control and optimization of each action to create materials with premium magnetic properties, low core losses, and high performance for use in electrical devices.
