II.Vertical Bottom Loading Vacuum Annealing Furnace
Description
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.
