Activity Description
The production process of heat-treated medium and heavy 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 heavy plate is a type of steel plate that undergoes a precision heat treatment process to improve its mechanical and physical properties. The heat treatment process includes steps such as heating, holding, and cooling, which are designed to alter the microstructure of the steel, thereby enhancing its strength, toughness, hardness, and wear resistance. 304 stainless steel heat-treated heavy plate is a stainless steel product whose performance is optimized through heat treatment. It is a stainless steel with excellent overall properties. The material's chemical composition primarily consists of approximately 18% chromium, 8% nickel, and a low carbon content. The high chromium content endows 304 stainless steel with excellent corrosion resistance, enabling the formation of a stable passive layer in various environments and effectively resisting chemical attack. The addition of nickel enhances overall structural stability, improves corrosion resistance, and provides good ductility and toughness. Heat treatment, particularly annealing, optimizes the lattice structure of 304 stainless steel, increasing its hardness and strength while maintaining favorable workability. This process also helps eliminate residual stresses, improving performance during welding and forming operations.

Technology comment
Heat treatment of medium and heavy plates is a critical process aimed at improving the mechanical properties and physical characteristics of steel plates by controlling heating and cooling. This process includes several main steps: normalizing, quenching, and tempering. The plate is heated to an appropriate temperature, typically above the critical point of the steel, and then cooled uniformly in a furnace or in air. Subsequently, the steel plate is reheated to a higher temperature and rapidly cooled (or sometimes slowly cooled), usually in water or oil. Finally, to eliminate the brittleness induced by quenching, the plate is heated at a lower temperature and then cooled again. The raw material for heat treated heavy plates is processed from products of short-process steelmaking.
