Stainless steel plates are produced by melting raw materials (iron ore, chromium, nickel) in an electric arc furnace, followed by refining (AOD/VOD) to control carbon levels, continuous casting into slabs, and hot rolling to reduce thickness. Finally, the plates undergo annealing, pickling to remove scale, and surface finishingKey Steps in Stainless Steel Plate Production:
* Melting and Refining: Raw materials (iron ore, nickel, chromium) are melted at high temperatures in an electric furnace. The molten metal is refined using Argon Oxygen Decarburization (AOD) or Vacuum Oxygen Decarburization (VOD) to remove excess carbon and impurities to meet specific grade requirements.
* Casting: The refined molten steel is cast into slabs, which are the raw, solid forms used for rolling, typically via a continuous caster.
* Hot Rolling (Plate Mill): The slabs are reheated to high temperatures and passed through heavy rollers to reduce thickness and form the desired plate structure.
* Annealing & Pickling (HRAP): The hot-rolled plates are heated to high temperatures (annealing) to relieve internal stresses, followed by "pickling" (acid cleaning) to remove oxidation scale and impurities.
* Cold Rolling (Optional): For thinner, more precise plates with a smoother surface, the plate may be rolled again at room temperature.
* Finishing and Cutting: Plates are cut to size and given surface treatments (e.g., No. 1, 2B, or mirror finish).
Production Tips & Safety
* Surface Protection: Protective coatings such as PE or PVC are applied to finished plates to prevent scratching.
* Safety Requirements: Workers must wear PPE including safety goggles, masks, and heat-resistant clothing due to high heat and sharp materials.
