Plates and Coils

1. Reheating: After the hot rolled coils pass through a pickling line, scale breaker machines and hydrochloric acid solutions are utilized to eliminate any surface scale or oxide film, which can cause surface flaws during the final stage of cold rolled steel processing.

2. Roughing: During this process, slabs with removed surface scale are shaped into rolled materials with the appropriate thickness and width. In the entry and exit area of the roughing mill, an edger utilizes an Automatic Width Control (AWC) system to roll the strip in the width direction.

3. Finishing Rolling: The finishing rolling process aims to adjust the thickness and width of a coil to the specified dimensions, producing a smooth surface and shape at the desired finishing temperature for its intended use. Our modern equipment, including Work Roll Shift Mills, Pair Cross Mills, and On-line Roll Grinders (ORG), enhances plant productivity and improves the quality of the finished coils by controlling the crown shape.

4. Run-Out Table and Coiling: Following the finishing mill, steel strips are conveyed to the run-out table for coiling. As the strips are rolled on the table, they are cooled to the appropriate temperature for coiling by being sprayed with water.

1. Steel Making: Our steelmaking process is pivotal in determining the quality and cost-effectiveness of our steel products. We have integrated state-of-the-art AOD, VOD, and continuous casting facilities to ensure the highest standards of steel production.

2. Hot Rolling: The slabs produced in our steelmaking plant undergo a meticulous hot rolling process, resulting in the creation of black coils with refined thickness and shape. These coils are further processed into white coils through heat treatment, pickling, and finishing at our annealing and pickling plant. The white coils are then utilized for cold rolling, pipe manufacturing, and sheet production, tailored to meet the specific requirements of our customers.

3. Plates: Our steelmaking plant produces slabs that are meticulously processed through rolling, heat treatment, and pickling to create high-quality plates. These plates are then cut into sizes as per customer orders and delivered accordingly. Our thick plates find applications in heavy chemical industries that demand exceptional corrosion resistance, such as petrochemicals, power plant facilities, paper manufacturing, and specialized shipbuilding.

4. Cold Rolling: XINYONGYUAN is equipped with advanced 20 high cluster mills, a bright annealing line, TLL (Tension Leveling Line), AFC (Automatic Flatness Control), and AGC (Automatic Gauge Control) to facilitate the production of cold-rolled products with a thickness range of 0.1-3.0mm and widths of up to 1580mm. This enables us to offer a diverse range of cold-rolled products in various shapes and surface treatments, meeting the specific needs of our customers.
