The precious metal wire annealing furnace is a high-temperature equipment used for annealing precious metal wires. It is usually used in the production process of precious metal products (such as gold, silver, platinum, palladium, etc.), especially in the manufacture of electrical, jewelry, and high-end electronic components, and plays a very important role.

Working principle:

1. Heating process: The annealing furnace increases the temperature in the furnace through a heating system. Usually, the heating temperature varies according to the characteristics of different precious metals. For example, the annealing temperature of gold and silver is generally between 300°C and 600°C, while platinum and palladium require higher temperatures.

2. Constant temperature maintenance: After reaching the required temperature, the temperature in the furnace will be maintained for a certain period of time to ensure that the lattice structure in the metal is adjusted and the internal stress is eliminated.

3. Slow cooling process: The annealing process usually requires the temperature in the furnace to cool down slowly to avoid metal embrittlement caused by rapid temperature changes.

Advantages of wire annealing furnace:

1. Improve the ductility of metal: Through annealing, the ductility and plasticity of precious metals are improved, making it easier to process into the desired shape.

2. Eliminate internal stress: Precious metal wires will produce internal stress during cold processing, and annealing can eliminate these stresses and reduce the risk of metal cracking.

3. Improve surface finish: By controlling the atmosphere in the furnace and the annealing process, oxidation or contamination problems on the surface of precious metals can be effectively controlled.
