The cold rolled steel coil (plate) production process is as follows:
Raw material preparation: Cold rolled steel coil production mainly uses hot rolled coil or hot rolled steel plate as raw materials. These raw materials first need to ry out quality checks to ensure they meet production requirements.
Pre-treatment: The raw material is heated and cleaned to remove surface oxides and dirt, making the surface of the billet smoother and ready for subsequent processing.
Cold rolling: The raw material is fed into multi-pass cold rolling mills for rolling. These mills usually consist of 4-6 passes, each with a decreasing diameter of rolls, and the raw material is rolled to the required thickness and width by pressing and stretching. In the process of cold rolling, surface treatments such as embossing, trimming, and polishing are also ried out on the steel plate.
Pickling: After rolling, the steel plate is pickled to remove the oxide skin and rust scale on the surface and to improve the flatness and finish of the steel plate surface.
Oiling: After pickling, the steel plate is oiled to prevent surface oxidation and corrosion, and to reduce friction and scratches during stacking, transport and processing.
Cutting: The steel plate is cut into the required length and width to meet the needs of different industries.
Packaging: The cut steel plates are packaged and labelled with relevant information, such as plate specifications, batch number and production date.
