Bell type furnace bell type annealing furnace bell type vacuum annealing furnace

  Bell vacuum bright annealing furnace is mainly used for bright annealing of non-ferrous metals such as copper, aluminum alloy and ferrous metal, ordinary carbon steel, silicon steel, alloy steel and other coils, coils and wires The bell type vacuum bright annealing furnace adopts heat-resistant stainless steel, and the inner cover is strictly sealed with the furnace platform, so that the workpiece material is always protected by high-purity nitrogen and hydrogen gas in the process of heating, heat preservation and cooling, so as to keep the surface of the annealing material bright without oxidation
In addition, due to the large air volume fan installed in the furnace, the protective atmosphere in the furnace forms a strong convection cycle to ensure the uniformity of furnace temperature, so as to obtain uniform physical properties of annealed materials
