Grain Oriented Silicon Steel Cores Process

Cores made of grain oriented silicon steel have an intricate and complicated production procedure, including several important steps that add to its highly desirable magnetic properties. But this specific procedure makes certain optimum grain positioning, making it possible for remarkable magnetic performance for transformers. Below, we’ll detail each crucial step:

1. Steelmaking and Casting

The initial stage begins with the choice of premium raw materials, mainly iron ore and silicon. These products are melted with each other in an electrical arc heating system or a basic oxygen heating system. The molten steel is then improved to achieve the desired chemical makeup, specifically in silicon material, which is critical for magnetic properties. After refining, the steel is cast right into pieces for further processing.

2. Hot Rolling

In the hot rolling process, the steel slabs are heated to a high temperature and rolled into thinner sheets. This hot rolling process makes certain the steel achieves a certain density while preserving its homogeneity. After rolling, the sheets go through a regulated cooling process.

3. Cold Rolling and Annealing

The hot-rolled sheets are further reduced in thickness with a cool rolling process. This action aligns the grains for a much better alignment and maximizes the magnetic properties. After cool rolling, the sheets undergo a decarburization annealing process, which minimizes the carbon content and enables additional grain alignment. This annealing process is vital as it gets rid of inner stress and anxieties and improves the grain structure.

4. Insulating Coating

An insulating coating is applied to the steel surface area to minimize eddy current losses. This coating also gives electrical insulation between the sheets in transformer cores. The insulating coating typically consists of magnesium oxide and various other chemical substances that provide high thermal stability and electric resistance.

5. Second Annealing (High-temperature Annealing)

The secondary annealing, carried out at a much greater temperature level, finishes the grain positioning procedure. The magnetic domain names are aligned in a single instruction, providing grain oriented silicon steel with its characteristic high leaks in the structure and reduced core loss. This step also creates a consistent grain dimension across the sheet.

6. Slitting and Final Evaluation

The completely processed sheets are slit right into certain widths and shapes required for transformer cores. They undertake extensive high-quality inspections to guarantee accurate specifications, including electrical resistances and magnetic properties. Any kind of deviation from the collection criteria results in rejection or reprocessing.

By adhering to these precise steps, the sector produces top-quality grain oriented silicon steel cores, which are essential parts of modern electrical transformers.
