Activity Description
The production process of normalized coils includes preheating, cooling, and post-treatment of steel coils, covering energy consumption, material consumption, waste management, and environmental emissions required during the production process.
Process Description
Silicon steel normalized coil is a special type of steel primarily used in electrical applications, especially in transformers and motors. This material is made from an alloy of iron and silicon, with silicon content typically ranging between 2% and 3%. The addition of silicon significantly enhances the electromagnetic properties of the steel, primarily by increasing electrical resistivity and reducing eddy current losses, which is crucial for improving energy efficiency and minimizing energy losses. Silicon steel normalized coils are widely used in the power industry and electrical manufacturing sector, particularly in the production of transformer cores and motor rotors or stators.

Technology comment
Normalizing, also known as normal annealing, is a heat treatment process that improves the toughness of steel by heating steel components to austenitize them, holding for a certain period, and then cooling in still air or protective atmosphere to form pearlite. Specifically, the workpiece is heated to a temperature above 727--912 °C for 40--60 minutes, held for a period of time, and then removed from the furnace and cooled in air, or by water spraying, mist spraying, or forced air cooling.
