Jewellery Wire Annealing Furnace 2 Pass-Hasung

working principle
(1) Heating process: The annealing furnace raises the temperature through a heating system. The heating temperature varies depending on the characteristics of different precious metals. For example, the annealing temperature for gold and silver is usually around 300-400 degrees Celsius. The annealing temperature for K gold is between 520-620 ° C, while platinum and palladium require higher temperatures.
(2) Constant temperature maintenance: Once the desired temperature is reached, maintain it for a specific period of time. This helps to adjust the lattice structure of the metal and eliminate internal stress.
(3) Slow cooling process: The annealing process requires a slow cooling stage inside the furnace. This slow cooling is crucial in preventing metals from becoming brittle due to sudden temperature changes.
Advantages of wire annealing furnace:
(1) Improving the ductility of metals: Annealing can enhance the ductility and plasticity of precious metals, making them easier to shape into desired shapes.
(2) Eliminating internal stress: Precious metal wires often generate internal stress during cold processing. Annealing can effectively eliminate stress and reduce the risk of metal cracking.
(3) Improving surface smoothness: through precise control
