High Strength Steel Plate S690 Processing

The first step in the production process is to select high-quality raw materials. The steel used in S690 plates is typically alloyed with elements such as manganese, silicon, and copper to improve its strength and toughness. These raw materials are carefully selected based on their chemical composition, physical properties, and other factors.

Once the raw materials have been selected, they are melted in a furnace at high temperatures. This process, known as smelting, helps to remove impurities from the steel and create a uniform composition. The molten steel is then poured into molds or rolled into sheets, depending on the specific application.

Next, the steel is subjected to a series of shaping processes that give it its final form. These processes may include hot or cold rolling, forging, or extrusion. Each of these processes helps to refine the steel's grain structure and increase its strength and toughness.

After the steel has been shaped, it undergoes a series of heat treatments to further improve its properties. These treatments, which may include quenching, tempering, or annealing, help to create a stable microstructure and enhance the steel's resistance to deformation and fracture.

Finally, the steel is subjected to rigorous quality control procedures to ensure that it meets the specifications for high strength steel plate S690. These procedures may involve testing the steel's mechanical properties, chemical composition, and microstructure, as well as visually inspecting the plates for defects or imperfections.
