FAQ
What is the ideal steam consumption to protect the wire during annealing?
The ideal steam consumption in a continuous annealing machine is a critical factor in guaranteeing the protection of the copper wire against oxidation and achieving high-quality copper annealing. Although the exact value may vary slightly depending on the specific design of the annealing machine and environmental conditions, a general range for steam consumption is typically between 6 and 8 kg/h at a pressure of 0.3 to 0.4 MPa. This steam flow is essential for creating an inert atmosphere within the annealing chamber, displacing oxygen and preventing the formation of oxides on the surface of the annealed copper wire.
Proper steam consumption not only protects the wire but also contributes to the efficiency of the copper heat treatment process, ensuring that the resulting soft copper wire has the desired mechanical properties and electrical conductivity. Precise control of this parameter is fundamental for final cable quality and for optimizing cable production.
