2e
Surface Overview: The surface is made of hot rolling black leather rolls formed by continuous rolling production lines, followed by solution annealing, phosphorus rupture and electrolytic pickling. The low roughness of the surface and good surface quality provide a stable and reliable gap for subsequent “special material” orders and cold rolled thin materials.
Process route: Hot roll black roll - black roll straight roll - annealing - phosphorus - pickling - rolling/plate finished product
Covered steel: 200 series, 300 series, 400 series
Thickness range: 1.0mm-3.0mm
2d
Surface Overview: After the material is rolled cold rolling, it is continuously annealed to change the microstructure and mechanical properties of the material to achieve the mechanical properties required by the customer; electrolysis and pickling are then used to remove oxidative rust on the surface of the steel bar, and then the shape of the plate is corrected by stretching.
Process route: Raw material number 1/2E-rolling - degreasing - annealing - electrolysis - pickling - painting and straightening - roll/plate finished products
Covered steel: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
2b
Surface Overview: After the material is rolled cold rolling, continuous annealing is stripped to change the microstructure and mechanical properties of the material to achieve the mechanical properties required by the customer; electrolysis and pickling are then used to remove rust on the surface of the steel strips, then the shape of the plate is corrected and the surface fineness is improved by tempering, rolling and drawing.
Processing route: Raw material number 1/2E-rolling - degreasing - annealing - electrolysis - pickling - tempering and rolling - painting and straightening - rolling / plate finished products
Covered steel: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
BA
Surface Overview: After the material is rolled by a high-precision 20 roll, it is annealed in an oxygen-free environment, degreased and bright annealing production lines to change the microstructure and mechanical properties of the material to meet the mechanical properties required by the customer; then the shape of the plate is corrected and the surface fineness is improved by tempering and rolling.
Process route: Raw materials - 20 volumes - Rolling - Vertical/horizontal bright annealing - Temperature rolling - Roll/plate finished products
Covered steel: 200 series, 300 series, 400 series
Thickness range: 0.25mm-1.5mm
