1. 2E
Surface overview: The hot rolled black roll is used to directly roll the black skin through the continuous rolling production line, and then the surface is formed after solution annealing, phosphorus breaking and electrolytic pickling. The surface has low roughness and good surface quality, providing stable and reliable embryo material for subsequent "special material" orders and cold rolled thin materials.
Process route: hot rolling black roll - black roll - annealing - phosphorus - pickling - roll/plate finished products
Covering steel types: 200 series, 300 series, 400 series
Thickness range: 1.0mm-3.0mm
2. 2D
Surface overview: After the material is cold rolled and calendered, the strip undergoes continuous line annealing to change the grain structure and mechanical properties of the material, so as to achieve the mechanical properties required by customers; After that, the oxidized rust on the surface of the steel strip is removed by electrolysis and pickling, and then the plate type is corrected by pulling.
Process route: raw material NO.1/2E -- rolling -- degreasing cleaning -- annealing -- electrolysis -- pickling -- pulling straightening -- coil/plate finished product
Covering steel types: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
3. 2B
Surface overview: After the material is cold rolled and calendered, the strip undergoes continuous line annealing to change the grain structure and mechanical properties of the material, so as to achieve the mechanical properties required by customers; After that, electrolytic and pickling are used to remove the oxidized rust on the surface of the steel strip, and then the plate shape is modified and the surface fineness is improved after tempering and rolling and drawing.
Process route: raw material NO.1/2E - rolling - degreasing cleaning - annealing - electrolysis - pickling - tempering rolling - drawing - coil/plate finished products
Covering steel types: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
4. BA
Surface overview: After high precision 20 roll cold rolling and calendering, the strip is annealed in an oxygen free environment with degreasing and bright annealing production line to change the structural grain and material mechanical properties, and achieve the mechanical properties required by customers; After quenching and tempering rolling to modify the plate and improve the surface fineness.
Process route: raw material - 20 high rolling - vertical/horizontal bright annealing - quenching and tempering rolling - coil/plate finished products
Covering steel types: 200 series, 300 series, 400 series
Thickness range: 0.25mm-1.5mm
