Description
This dataset describes the drawing and annealing process for 1 kg of copper rod, resulting in the production of 0.9997 kg of copper wire, which is primarily used in wire and cable manufacturing. This dataset should be used in conjunction with 1 kg of copper rod. Data are collected from multiple cable production processes. The dataset includes auxiliary materials, energy consumption, and waste generated during the drawing and annealing process. Infrastructure such as manufacturing of production equipment and construction of facilities are excluded from the system boundaries of this dataset. The data quality is associated with relatively high uncertainty.
Activity Description
This activity describes the process of producing copper wire through drawing and annealing of copper rods. Drawing and annealing is a copper conductor manufacturing process, which often occurs together in copper conductor production. Drawing refers to the technical method of forcing metal through a die under external force, thereby reducing the cross-sectional area of the metal and obtaining the required shape and dimensions of the cross-section. Annealing is used to eliminate internal stresses generated in the metal due to external forces.
Process Description
Wire drawing and annealing are essential steps in the copper wire production process. Wire drawing refers to a technical process where metal is forcibly pulled through a die under external force, resulting in a compressed cross-sectional area and achieving the desired shape and dimensions. Annealing is used to relieve internal stresses induced in the metal by external forces.
