Grain Oriented Electrical Steel Production Line
Laser Scribing Technology for CRGO Steel
Laser scribing, also known as magnetic domain refinement technology, is applied to finished grain oriented electrical steel with an insulating coating. The laser irradiates the steel surface in dots or lines, refining magnetic domains within a 20µm subsurface layer. This process reduces core loss and improves the performance of CRGO steel for transformer core laminations.
20-High Rolling Mill
The 20-high rolling mill processes grain oriented electrical steel with strict thickness control. For standard CRGO steel, it performs two cold rolling passes: reducing the 2.3mm pickled coil to 0.63mm, then to a final thickness of 0.262±0.005mm after decarburization annealing. For high-grade Hi-B steel, it completes one-pass rolling in 6 passes, directly reducing 2.3mm material to 0.257±0.005mm or 0.22±0.005mm. This high-precision process ensures consistent flatness and dimensional accuracy for high-performance transformer core laminations.
On-Site Production Area
Our organized production area supports key processes for grain oriented electrical steel. Regular on-site inspections ensure stable workflows and consistent product quality.
