Description
After heat treatment, carbon steel wide and heavy plates exhibit improved strength, toughness, and wear resistance, making them suitable for manufacturing heavy machinery equipment, automotive components, construction machinery, and other applications. Due to the good workability and weldability of carbon steel, the heat treated plates can undergo further processing and forming to meet complex engineering requirements. The production process of heat treated wide and heavy plates includes heating, soaking, cooling, and post-treatment of the plates, covering energy consumption, material consumption, waste management, and environmental emissions associated with the production process. This dataset is inferred from multiple data sources.
Activity Description
The production process of heat-treated wide and thick plates includes heating, soaking, 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 treated wide and thick plates are steel plates processed through special heat treatment procedures, 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. After heat treatment, wide and thick carbon steel plates exhibit improved strength, toughness, and wear resistance, making them suitable for producing heavy-duty machinery, automotive components, and construction equipment. Due to the good workability and weldability of carbon steel, heat-treated wide and thick plates can undergo further processing and forming to meet complex engineering requirements.

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.
