Normalizing refers to the process of heating metal workpieces to a certain temperature, holding them at that temperature for a period, and then performing slow cooling. Normalizing can reduce internal stresses in the material, improve the crystal structure of the material, and enhance the material's ductility and malleability. The cooling rate of normalizing is slightly faster than annealing, and the normalized microstructure is finer than the annealed microstructure, resulting in improved mechanical properties of the material. This process represents the normalizing of 1kg of steel, corresponding to 0.989kg of steel after normalizing, and should be used in conjunction with production data for 1kg of steel. Data originates from the production processes of shafts, gearboxes, and other electromechanical equipment accessories.
