Description
Heat treated wide and heavy plates are steel plates processed through special heat treatment techniques, 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 heavy carbon steel plates exhibit improved strength, toughness, and wear resistance, making them ideal for producing heavy machinery, automotive parts, construction equipment, and similar applications. The production process of heat treated wide/heavy plates includes heating, soaking, cooling, and post-treatment of the plates, covering energy consumption, material consumption, waste management, and environmental emissions required during production. This dataset is compiled from data obtained from multiple sources.

Process Description
Thermally treated wide and thick plates are steel plates processed through special heat treatment techniques, 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. Carbon steel wide and thick plates, after heat treatment, exhibit improved strength, toughness, and wear resistance, making them suitable for producing heavy-duty machinery, automotive parts, and construction equipment. Thermally treated wide and thick stainless steel plates are stainless steel sheets subjected to special heat treatment processes to enhance their mechanical and physical properties. This type of wide and thick plate has large dimensions, suitable for various industrial and construction applications, especially in situations requiring high corrosion resistance and strength.

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.
