Horizontal Vacuum Water Quenching Furnace

It is used for the solution treatment of titanium alloy in aerospace industry, such as TC4, TC16, TC18, TC21, beryllium bronze in aircraft instrument elastic elements; precision alloy in aircraft sensor like Ni-based and Co-based high elastic alloy 3J1, 3J21, Ni-based constant elastic alloy 3J53, stainless steel in the field of nuclear energy like17-4PH, 410.

Technical Features
1. It is horizontal, twin chamber structure, all stainless steel construction.
1.All metal hot zone, great temperature uniformity.
2.The heating elements adopt unique non-ceramic supporting technology. It can be used five years without any insulation problem.
3.The inner trolley is overlap-type stretchable structure with frequency converting function. It has a stable transportation speed with "slow-fast-slow” steps, which makes the transportation time very short.
4.Large loading capacity and high efficiency.
5.Water tank temperature 5-10°C.
