The customized 1700 ℃ box type muffle furnace, with its ultra-high temperature performance, precise temperature control, and flexible customization ability, can support various high-precision and complex process requirements. The following is a detailed explanation of its core process applications and customization advantages:
1. Core Process Application Fields
Ceramic sintering and crystal growth
High temperature densification treatment: Structural ceramics such as silicon nitride and silicon carbide need to be sintered at 1600-1700 ℃. By customizing the furnace size (such as deep narrow design) and controlling the gradient temperature field, deformation free sintering of irregular workpieces such as aviation blade coatings and ceramic based composite materials can be achieved.
Crystal growth: Sapphire, zirconia and other crystals need to be slowly cooled at high temperatures to form a uniform lattice. Customized temperature control curves (such as step cooling) can optimize crystal quality.
metal heat treatment
High temperature alloy strengthening: Nickel based and cobalt based high-temperature alloys require solution treatment or aging treatment at 1700 ℃. Customized heating element layout (such as zone independent control) can correct the furnace temperature field gradient to ensure material performance consistency.
Preparation of metal ceramic composite materials: By using atmosphere control functions (such as inert gas protection) to prevent metal oxidation at high temperatures, the composite sintering of metal and ceramic is achieved.
Catalytic Research and Reaction Engineering
Catalyst activation: Simulate the high-temperature activation process of catalysts at 1700 ℃ to optimize the reaction pathway (such as the preparation of catalysts for automobile exhaust treatment).
High temperature catalytic reaction: Customize a multi atmosphere control system (such as introducing hydrogen and ammonia) to study the catalytic reaction mechanism at high temperatures (such as Fischer Tropsch synthesis and methane reforming).
Development of new materials
Ultra high temperature ceramics (UHTCs): Developing carbide/nitride ceramics of refractory metals such as hafnium and zirconium requires hot pressing sintering at 1700 ℃. Customized mechanical load stacking functions (such as top rod loading devices) can synchronously apply pressure to improve material density.
Solid state electrolyte synthesis: For example, sulfide solid-state battery electrolytes (Li ∝ PS ₄) require a fully automated process of “temperature rise → constant temperature → pressure rise → cooling” through a programmable system at high temperatures. Customized process templates can improve preparation efficiency.
Geology and Energy Research
Crustal high temperature and high pressure simulation: Simulate the mineral transformation mechanism of shale gas reservoirs under conditions of 1300-1700 ℃ and 10MPa, control the temperature and pressure rise process through multi-stage programs, and observe the quartz scale quartz phase transition and gas permeability changes in situ.
Nuclear waste treatment: Study the stability of glass solidified bodies at high temperatures, customize large capacity furnaces (such as ≥ 1m ³) to support kilogram level sample processing, and shorten the cycle from laboratory to industrialization.
2. Customized process advantages
Temperature control accuracy
PID intelligent regulation: The temperature control accuracy reaches ± 1 ℃, supporting more than 50 programmable curves (such as step heating, constant temperature maintenance, gradient cooling), meeting complex process requirements.
Three dimensional temperature field monitoring: Real time monitoring is achieved through embedded thermocouple arrays, and the uniformity of the temperature field is improved to ± 1.2 ℃ (at 1200 ℃) to ensure consistency in material properties.
Furnace structure and materials
Special shaped furnace design: For long axis and thin-walled workpieces, customize “deep narrow” or “gradient temperature field” furnaces to avoid deformation.
Gradient composite structure: Adopting a multi-layer design of zirconia mullite, the thermal shock resistance is improved.
Atmosphere and pressure control
Multi channel gas system: supports the introduction of corrosive gases such as hydrogen and ammonia (with explosion-proof devices), or achieves non oxidizing sintering through a vacuum interface (vacuum degree ≤ 10 ⁻ Pa).
Pressure regulation: Integrated mechanical load superposition function, suitable for hot pressing sintering experiments.
Safety and Environmental Design
Multiple protection mechanisms: over temperature alarm, leakage protection, gas leakage monitoring, in compliance with laboratory safety standards.
Energy saving design: The nano fiber modular insulation layer reduces the outer wall temperature to below 45 ℃, improves thermal efficiency, and is more energy-efficient than traditional models.
3. Typical application cases
Sintering of coating on aircraft engine blades
A certain research institute has achieved continuous annealing of automotive steel and integrated design of waste heat quenching through customized ceramic fiber roller bottom furnace, reducing energy consumption of the production line and improving product qualification rate.
Preparation of Solid State Battery Electrolyte
In the synthesis of solid-state battery electrolytes (such as Li ∝ PO ₄), a fully automated process of “temperature rise → constant temperature → pressure rise → cooling” is achieved through a programmable system to prepare electrolyte sheets with higher density, which is much more efficient than traditional step-by-step processes.
Simulation of high temperature and high pressure in the Earth’s crust
Simulate the high-temperature and high-pressure environment of the Earth’s crust (1300 ℃, 10MPa), study the mineral transformation mechanism of shale gas reservoirs, simulate the process of formation temperature and pressure rise through multi-stage programs, and observe the quartz scale quartz phase transition and gas permeability changes in situ.
