The above parameters can be adjusted according to the process requirements and are not used as the basis for acceptance. The specific technical scheme and agreement shall prevail.

Technical Features
1. The furnace is horizontal, single chamber, horizontally loading structure. The way of opening door is optional according to customer's requirement.
2. The hearth consists of wide nickel-chromium heating zone and multi-layer stainless steel heat insulation with good temperature uniformity performance.
3. Tempering is finished under the high vacuum. The jobs after treatment are bright without any color changes.
4. The fast cooling system composed of inner heat exchanger and gas cooling circulation can effectively prevents components from tempering brittleness.
5. Vacuum tempering tube furnaces have convection heating device, which can ensure the temperature uniformity at the state of low temperature.

Optional Configuration of High Vacuum Tempering Furnace
1. Furnace door: rotating; slide open; vertical up and down,
