Manufacturing

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.

Steel is a crucial material in construction, manufacturing, and various other industries. H-beam steel, a prevalent structural steel, finds widespread use across diverse sectors. Notably, the surface of H-beam steel is characterized by its absence of slope, with the upper and lower surfaces running parallel. The cross-sectional properties of H-beam steel surpass those of traditional I-beam steel, channel steel, and angle steel, making it a preferred choice in numerous applications.

1. Input process: The input point of the electrogalvanizing wire is equipped with a pay-off reel, a shearing machine, a welding machine, a looper, and a tension and straightening machine. Pay-off reels transport stacked or cold-rolled steel to shears, which cut and join them in preparation for welding. Next comes the welding process.

2. Pre-treatment process: Electrolytic cleaning line, consisting of an electrolytic tank, acid bath, and rinsing tank, is used to remove contaminants and oxide films on the surface of steel before electroplating.

3. Electroplating: The CAROSEL method, as well as other electrogalvanizing techniques, involves plating one side at a time using a conductor roller. This process can produce double-sided, single-sided or different-sided electroplated plates. Additionally, the horizontal method allows both sides of the sheet to be plated simultaneously, resulting in a double-sided plated sheet.

4. Phosphate Film Coating: A phosphate film is applied to the surface of the zinc layer through a chemical or electrochemical reaction. The film provides temporary corrosion protection and provides a safe substrate for painting.

5. Anti-fingerprint process: Organic, inorganic or organic-inorganic hybrid films are applied to the surface of steel plates to enhance corrosion resistance and impart desired properties, such as resistance to fingerprint marks and improved processability.

6. Output process: The exit of the production line includes output loopers, tension reels and automatic packaging lines to protect the products after coil winding.

1. Surface treatment: After cold-rolled steel plate processing, the charged steel plate is passed through an alkaline solution, triggering an electrochemical reaction to remove residual rolling oil and other contaminants, thereby cleaning the surface.

2. Annealing: The material properties of pre-treated steel plates are modified and enhanced by recrystallization during the annealing process.

3. Hot-dip galvanizing: After the annealing furnace, the steel plate is immersed in a zinc pot and the surface is covered with molten zinc. The desired coating weight is achieved by using high-pressure air in an air knife to remove excess zinc before curing.

4. Galvanized Annealing: After air knife treatment, the surface of the steel plate can be coated with zinc compounds and then reheated during the annealing process. This allows zinc atoms to diffuse into the iron, forming a zinc-iron alloy.

5. Surface Treatment and Coating: In order to obtain a smooth surface and exquisite finish, the steel plate is machined flat. In addition, in order to prevent the formation of white rust on the surface of active zinc and enhance corrosion resistance, the surface is coated with chromium-free resin.

6. Inspection and Coiling: Steel plates are thoroughly inspected and coiled to ensure quality and prepare them for further processing.
