Customized 1700 degree box type muffle furnace for metal heat treatment

Customized 1700 ℃ box type muffle furnace can efficiently meet the needs of metal heat treatment. Its core advantages and customization points are as follows:

1. Core performance advantages
Ultra high temperature capability
The furnace is stable at 1700 ℃ and can handle refractory metals such as tungsten and molybdenum, as well as high-temperature alloys, meeting the requirements of processes such as solution treatment and aging treatment. For example, Inconel 718 can eliminate work hardening and improve plasticity through graded cooling after solid solution treatment at 1700 ℃.
Precise temperature control system
Adopting PID intelligent adjustment algorithm, the temperature control accuracy reaches ± 1 ℃, and supports multi-stage heating/cooling programs (such as step heating, constant temperature maintenance, gradient cooling).
Equipped with high-precision thermocouples or thermistor sensors to monitor the temperature inside the furnace in real time, ensuring that the heat treatment process follows the preset process curve and improving product quality consistency.
Uniform temperature field design
By using multi zone heating control technology, the temperature in different areas of the furnace can be independently adjusted to reduce temperature gradients.
To avoid material deformation or performance differences caused by uneven temperature, such as during annealing of aviation blades, a uniform temperature field can ensure the accuracy of blade shape.
High temperature resistant structural materials
The furnace is made of high-quality refractory materials such as corundum mullite and polycrystalline alumina fibers, which have strong thermal shock resistance and can withstand frequent cold and hot cycles.
The heating element is made of silicon molybdenum rod, which is resistant to high temperature (1700 ℃), anti-oxidation, has high heating efficiency, and has a longer lifespan.

2. Adaptability of metal heat treatment process
Annealing process
Annealing of high-temperature alloys: Introduce argon gas atmosphere at 1700 ℃, and use customized temperature control curves (such as heating to 1700 ℃ for 2 hours, constant temperature for 2 hours, and cooling in the furnace to 600 ℃ before air cooling) to eliminate work hardening and improve material plasticity.
Titanium alloy annealing: Under argon protection, a gradient temperature field design (furnace center temperature of 1650 ℃, edge temperature of 1600 ℃) is used to avoid deformation of thin-walled parts due to excessive temperature differences.
quenching and tempering
Steel material quenching: After rapid heating to 1700 ℃, high-pressure gas quenching (such as nitrogen quenching) is used to achieve a balance between high hardness and toughness.
Tempering of mold steel: Tempering in stages at 1700 ℃ to eliminate quenching stress and improve the service life of the mold.
Solid solution and aging treatment
Nickel based alloy solution treatment: Hydrogen gas atmosphere is introduced at 1700 ℃, and customized mechanical load stacking function is used to improve material density and higher bending strength.
Aluminum alloy aging treatment: precise control of aging time and temperature at 1700 ℃ to optimize material mechanical properties.

3. Key points of customized design
Furnace size and shape
Customize the furnace according to the size of the workpiece (such as a deep narrow furnace with a diameter of 50mm × 800mm suitable for long axis workpieces) to reduce annealing deformation.
Irregular furnace design (such as gradient temperature field furnace) can adapt to complex shaped workpieces (such as aviation blades, ceramic tubes).
Atmosphere control system
Multi channel gas system: supports the introduction of inert gases (argon, nitrogen) and reducing gases (hydrogen) to prevent material oxidation.
Vacuum environment: Optional vacuum pump (vacuum degree ≤ 10 ⁻ ³ Pa) to meet the requirements of non oxidizing annealing (such as certain ceramic materials).
Pressure regulation function
Integrated mechanical load stacking device (such as 0-50kN top rod loading device), suitable for hot press annealing (HIP), to enhance material density.
Safety and energy-saving design
Safety protection: over temperature alarm, leakage protection, door control safety device (automatically shuts off when the furnace door is opened).
Energy saving design: The nanofiber insulation layer reduces the outer wall temperature to below 45 ℃, improves thermal efficiency, and reduces long-term operating costs.

4. Typical application cases
Annealing of aircraft engine blades
Customized furnace size of 800 × 300 × 300mm, matched with blade shape, designed with gradient temperature field (center temperature of 1650 ℃, edge temperature of 1600 ℃) to avoid bending deformation.
Annealing under argon atmosphere to eliminate processing stress and improve material toughness.
Solution treatment of high-temperature alloys
By introducing a hydrogen atmosphere at 1700 ℃ and utilizing customized mechanical load stacking functions, nickel based alloys with higher bending strength were prepared, resulting in improved interfacial bonding strength.
Ceramic material sintering annealing
Zirconia ceramics are vacuum annealed at 1700 ℃, and residual stresses are eliminated through graded cooling (10 ℃/min → 5 ℃/min), resulting in higher bending strength and improved toughness.
