Vertical bottom loading annealing furnace is satiable for bright annealing of materials like tool steel, die steel, high-speed steel, ultra-strength steel, magnetic material, stainless steel and non-ferrous metal. It is also specially used for vacuum annealing of large size jobs which is easy to deform, such as long pole-shape parts, shaft parts, board parts, etc.
The parameters can be adjusted according to the process requirements, but not as the acceptance standard. The detailed specifications will be described in the technical proposal and agreement
