Oriented silicon steel Description
Oriented silicon steel, also known as cold-rolled oriented silicon steel, contains 2.9% - 3.5% silicon. Its crystal grains are arranged in a specific orientation, which gives it unique magnetic properties. This type of silicon steel has extremely low core loss and high magnetic permeability along the rolling direction. It's mainly used in manufacturing transformer cores, significantly enhancing transformer efficiency and reducing energy consumption. In the power industry, its application helps save a large amount of electricity. Also, crgo silicon steel plays an important role in new energy and electronic device manufacturing fields.

Manufacturing Process and Performance Control of High Permeability Grain-Oriented Silicon Steel (HiB)
The production of GO silicon steel is regarded as the "crown jewel" of metallurgical industry, involving 18 critical processes including steelmaking, hot rolling, normalization, and cold rolling. In the decarbonization annealing stage, the material must be treated for 5 minutes in an 800°C hydrogen-nitrogen mixed atmosphere to maintain carbon content below 30ppm. For more sophisticated HiB steel (high permeability grain-oriented silicon steel), additional laser scribing is required to create micron-scale grooves on the surface, reducing magnetic domain width to under 2mm.
The shape control in cold rolling is an art form - a six-high rolling mill must reduce 3mm-thick hot-rolled plates to 0.3mm with thickness deviation within ±3μm. The continuous decarbonization annealing line utilizing electromagnetic induction heating can uniformly heat steel strips to 830°C at 20m/min, forming perfect secondary recrystallization structures. The precise control of these processes directly determines the final magnetic performance grade of crgo silicon steel.
