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
Thermomechanically processed wide and heavy steel plates are a type of steel plate treated by special heat treatment processes, primarily used in applications requiring high strength and wear resistance, such as heavy machinery, construction structures, shipbuilding, and pressure vessels. These steel plates typically have a thickness exceeding 60 mm and widths reaching several meters, making them suitable for manufacturing large structural components. Heat-treated wide and heavy carbon steel plates exhibit improved strength, toughness, and wear resistance, making them ideal for fabricating heavy-duty machinery, automotive parts, and construction equipment. 304 stainless steel thermomechanically processed wide and heavy plates are high-quality stainless steel plates subjected to specific heat treatment processes, widely used across various industrial and construction applications. 304 stainless steel, as the most common austenitic stainless steel, contains approximately 18% chromium and 8% nickel, offering excellent corrosion resistance and good mechanical properties.

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.
