The bell type copper wire annealing furnace is mainly used for annealing and aging of copper wire, aluminum alloy stranded wire, coil and alloy wire. It is an ideal heat treatment equipment for cable manufacturers.

The bell type copper wire annealing furnace adopts heat-resistant stainless steel, and the inner cover is strictly sealed with the hearth, so that the workpiece material is always under the protection of high-purity nitrogen and hydrogen gas in the process of heating, heat preservation and cooling, so as to keep the surface of annealed material bright without oxidation.

According to the size of the user's coil, the annealing basket is adopted or directly stacked on the charging tray of the bell type furnace.

In addition, due to the large air volume fan installed in the furnace, the protective atmosphere in the furnace forms a strong convective circulation, and the air is supplied to the annealing tank to reduce the temperature difference in the annealing, ensure the furnace temperature uniformity, so that the annealing material can obtain uniform physical properties.
