DIN EN 10130 cold rolled coil production process

Raw material preparation: Standard hot-rolled steel coils are used as raw materials, and their composition must meet the mechanical property requirements of DIN EN 10130 for cold-rolled substrates.

Pickling: Remove the iron oxide scale on the surface of the hot-rolled steel coil by acid immersion or spraying to ensure surface cleanliness and provide conditions for subsequent cold rolling. After pickling, rinse and dry to avoid residual corrosive media.

Cold rolling: The pickled steel coil is continuously rolled at room temperature (including rough rolling, intermediate rolling and finishing rolling) to form a hardened coil with precise thickness.

Annealing: After the steel coils are welded at the ends, they are continuously passed through the annealing furnace, which is highly efficient and suitable for products with high flatness requirements. Annealing can eliminate the stress and hardening caused by cold rolling and restore the ductility of the material.

Flattening: Improve the surface flatness through light rolling and adjust the mechanical properties to meet the dimensional tolerance requirements of DIN EN 10130.

Trimming and coiling: Use a disc shear to remove edge burrs and ensure width accuracy; coil or cut according to order requirements.

Surface treatment: Optional oiling or galvanizing (such as galvanized substrate) to enhance rust resistance.

Quality inspection and packaging: Key indicators such as thickness, hardness, and surface defects are inspected to ensure compliance with DIN EN 10130 standards. The inner diameter after coiling is usually 610mm, and the weight range is controlled between 6-13.5 tons.

Key process-related standards: DIN EN 10130 clearly stipulates the chemical composition, mechanical properties (such as yield strength, elongation) and surface quality requirements of cold rolled carbon steel coil. The annealing process must ensure that the final product meets the toughness indicators specified in the standard.
