Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The production process of heat-treated wide and thick plates includes heating, heat preservation, cooling, and post-treatment of the plates, covering energy consumption, material consumption, waste management, and environmental emissions required during the production process.
Process Description
Heat-treated wide and heavy steel plates are steel plates processed through special heat treatment techniques, primarily used in applications requiring high strength and wear resistance, such as heavy machinery, structural construction, shipbuilding, and pressure vessels. These steel plates typically have a thickness exceeding 60 mm and widths reaching several meters, making them suitable for the manufacturing of large structural components. After heat treatment, carbon steel wide and heavy plates exhibit improved strength, toughness, and wear resistance, suitable for manufacturing heavy mechanical equipment, automotive parts, and construction machinery. 20Cr13 stainless steel heat-treated wide and thick plate is a type of martensitic stainless steel plate. This stainless steel contains approximately 13% chromium and a relatively high carbon content. This chemical composition enables it to achieve excellent mechanical properties and wear resistance after appropriate heat treatment processes such as quenching and tempering.

Technology comment
Heat treatment of heavy and wide plates is a crucial process used to enhance the mechanical properties and physical characteristics of steel plates. This process includes several main steps: normalizing, quenching, and tempering. The heavy plate is heated to an appropriate temperature, typically above the critical point of the steel, and then uniformly cooled either in a furnace or in air. Subsequently, the steel plate is heated again to a higher temperature and rapidly (or slowly) cooled, usually in water or oil. Finally, to eliminate the brittleness induced by quenching, the plate is reheated to a lower temperature and then cooled again.
