Vacuum annealing furnace, mainly suitable for stainless steel deep drawing parts such as plumbing equipment, water expansion parts, pins, medical equipment, stainless steel nails, stainless steel screws, pressure riveting parts, stainless steel bearings, watch cases, watch straps, knives, miniature shafts, automatic It is a multi-purpose furnace for continuous bright annealing, solid solution, demagnetization and stainless steel quenching treatment of stainless steel products such as self-drilling and tableware under the control of protective atmosphere.

Mainly suitable for stainless steel deep drawing parts such as plumbing equipment, water expansion parts, pins, medical equipment, stainless steel nails, stainless steel screws, pressure riveting parts, stainless steel bearings, watch cases, watch straps, knives, micro shafts, self-tapping and self-drilling, Multi-purpose furnace for continuous bright annealing, solid solution, demagnetization and stainless steel quenching treatment for stainless steel products such as tableware under the control of protective atmosphere. After treatment, the surface of the product is smooth, non-oxidized and non-decarbonized. It has the advantages of high production efficiency, low energy consumption, less pollution, convenient operation and use, and low labor intensity. It can also be used for brazing and sintering of metal materials. The most advanced products abroad in the early 1990s.

What should I do if it is annealed in a vacuum furnace but the oxidation is still serious?

In the vacuum annealing furnace, the copper strip is oxidized, indicating that the vacuum furnace is leaking.

1. Check whether the working vacuum of the vacuum pump is normal. Use a vacuum gauge to check the vacuum at the inlet of the vacuum pump to see if it can reach the ultimate vacuum of the pump. If it is not reached, change the oil, or repair, and then change the pump.

2. Use a leak detector to detect leaks in the vacuum furnace. If a leak detector is not available (leak detectors are expensive), use acetone (denatured alcohol) to pick up the leak. General leak rate, it should be no problem.
