In a word, grain oriented silicon steel strip is an essential product in the electrical sector, supplying superior magnetic properties that boost the effectiveness and performance of transformers and other electro-magnetic gadgets.
The production process of grain oriented silicon steel strips entails several exact steps to guarantee the end product satisfies the needed magnetic properties and quality standards.
The process starts with the selection of resources, normally high-purity iron ore and silicon. These materials are melted in an electric arc furnace to produce molten steel which contains 3% silicon, which is necessary for improving the magnetic properties of the steel.
As soon as the liquified steel is improved, it is cast into slabs via continual casting. These slabs are after that subjected to a collection of hot rolling operations. Hot rolling lowers the thickness of the slabs into thinner plates, a procedure that has to be carefully controlled to accomplish the desired density and structure. The temperature level and rolling problems are enhanced to guarantee the steel establishes the needed grain structure.
Complying with hot rolling, the steel goes through cold rolling to further lower its thickness and improve surface finish. Cold rolling also enhances the magnetic properties by fine-tuning the grain structure. After cold rolling, the steel is hardened in a controlled ambiance. This annealing procedure is important as it creates the wanted grain alignment. The steel is heated to high-temperature levels and then slowly cooled, which assists in straightening the iron crystals in particular instructions, therefore improving its magnetic leaks in the structure.
After annealing, the steel strip is coated with a layer of protecting material. This layer is important to protect against eddy current losses and enhance the performance of the steel in electric applications. The coated strips are then subjected to a final inspection to guarantee they meet the required requirements in terms of thickness, magnetic properties, and surface quality.

| Melting | Molten steel production from iron ore and silicon | Temperature: 1600-1700 °C |
| Continual Casting | Formation of steel slabs | Piece thickness: 200-300 mm |
| Hot Rolling | Reduction of slab thickness into plates | Temperature level: 1100-1200 °C |
| Cold Rolling | Further reduction of thickness and appearance improvement | Final thickness: 0.2-0.5 mm |
| Annealing | Heat treatment to create grain alignment | Temperature: 800-1000 ° C |
| Coating | Application of insulating product | Finish thickness: 5-10 µm |
| Inspection | Final quality check | Thickness tolerance: ± 0.02 mm |
