Hot band in. Laser-scribed, certified coil out.
Seven process stages turn American hot band into finished grain-oriented steel — an eighth puts it on your dock. Every line is specified with Tenova, one of the few OEMs worldwide that can build a complete GOES finishing line.
GOES-grade hot band arrives by rail from U.S. mills, is inspected, edge-slit to width, and staged to the line.
INSPECTED · STAGED
Strips the mill scale in acid and sets the starting microstructure for cold reduction.
NORMALIZED
The 20-high reversing mill takes the strip to final gauge in successive passes — the heart of the mill we are rebuilding on this site.
FINAL GAUGE
Burns residual carbon out of the strip and lays down the MgO separator that keeps wraps from welding in the long anneal.
MgO COATED
A days-long box anneal near 1,200 °C drives secondary recrystallization: the Goss grain consumes the matrix, and the steel's easy axis lines up with the rolling direction.
{110}⟨001⟩
Thermal flattening under tension, then the insulating top coat is applied and baked on — the film that isolates lamination from lamination in the core.
INSULATION COATED
Transverse laser scribing refines the magnetic domain spacing — the step that cuts core loss to premium grade — with 100% surface inspection and per-coil magnetic testing.
CERTIFIED
Master coils are slit to order width, packaged for the ocean-of-air between here and your core line, and loaded to rail or truck.
