Xi’an Koja Photoelectric Technology Co., Ltd. had participated in the construction of VTS-120 Horizontal Vacuum Annealing Furnace. Deliberated and proved by Technology Transformation Office, it officially has come into use recently. After examination, each index of it had met the design requirements and it could satisfy the annealing demand of the whole institute. It means that XIOPM is capable to do vacuum heat treatment to titanium castings.
VTS-120 Horizontal Vacuum Annealing Furnace is composed of vacuum furnace body, heating system (furnace pipe), vacuum system, reverse air cooling system, water-cooling system, feeding system, electrical control system and alarm system. The vacuum furnace body is a water-cooling system with double-decked jackets; the heating elements are arranged evenly in circle direction and separated to three sections for independent heating, the three-point of temperature control makes sure the temperature uniformity; the vacuum system is composed of triplex pump vacuum air-removed system and vacuum measurement.

With clean, economic, pollution-free, non-oxidation and small deformation characters, the annealing furnace can not only apply in the vacuum annealing of titanium castings and others but also in the stress relieving and machining and non-oxidation bright annealing of aluminum and other alloys. Meanwhile, it is also applicable to the vacuum annealing of the materials with operation temperature below 800℃.
