[Anealing furnace]

CDOCAST annealing furnace is an equipment specially designed for the annealing of precious metals. The heating principle is based on a high temperature resistance wire heating, so that the heating temperature is more uniform and the whole heating process can be controlled.

The annealing furnace comes with a cooling water tank. Therefore, the annealing workpiece can be quickly cooled after heating , what is more, the entire annealing process can be carried out under inert gas (nitrogen protection)

The annealing furnace can also be equipped with ammonia heating and decomposition device, because ammonia can be decomposed into nitrogen and hydrogen after heating, and hydrogen can also be used for reduction to make the workpiece brighter. On the other hand, ammonia is cheaper, so, Some customers will choose a furnace with ammonia heating and decomposition.

The heating chamber is made of stainless steel, which is durable and can withstand high temperatures. A combustion device is installed in the front of the heating chamber to prevent oxygen from entering the heating chamber. Because oxygen is burned out at the furnace mouth, the entire annealing process is oxygen-free. It prevents the oxidation of the workpiece. When the annealing is completed, you only need to push and rotate the loaded metal rack to let the workpiece fall down into the cooling pool to achieve rapid cooling. The annealed workpiece can be easily taken out of the annealing pool. easy and convenient.
