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

The annealing furnace adopts heat-resistant stainless steel inner cover and the hearth is strictly sealed, 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 annealing material surface 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.
