Description
Annealing refers to a process in which a metal workpiece is heated to a certain temperature, held for a period of time, and then slowly cooled. Annealing reduces internal stresses in the material, improves the crystalline structure, enhances ductility and plasticity, and allows adjustment of material hardness by controlling temperature and time during heating and cooling. This process represents the annealing of 1 kg of steel, with water as the cooling medium, yielding 0.969 kg of annealed steel. This process should be used together with the production data of 1 kg of steel. The data inventory is formed by aggregating data from the annealing processes involved in the production of bearings, shearing blades, rollers, and other mechanical and electrical equipment components.
Activity Description
The annealing process includes preparation of the workpiece, preparation of the cooling medium, heating, heat preservation, and annealing. This dataset includes direct electricity consumption of the machine, water consumption, and consumption of coatings and water glass.
Process Description
Annealing refers to a process in which a metal workpiece is heated to a certain temperature, held for a period of time, and then slowly cooled. Annealing can reduce internal stresses in the material, improve its crystalline structure, enhance ductility and plasticity, and adjust the material's hardness by controlling temperature and duration during the heating and cooling phases. This process represents the annealing of 1 kg of steel, with water as the cooling medium, resulting in 0.969 kg of annealed steel. This process should be used in conjunction with the production data for 1 kg of steel.

Technology comment
Prior to annealing, preparation is required, including cleaning contaminants and grease from the surface of the metal workpiece and performing necessary finishing. After heating and heat preservation, cooling is carried out using different cooling media according to the processing requirements. Common cooling media include air, water, and oil; in this dataset, the cooling medium refers to water.
