Introduction
A vacuum furnace with ceramic fiber lining is a type of vacuum furnace that uses ceramic fiber as its insulation liner. Ceramic fiber is a lightweight, porous material with excellent thermal insulation properties. This makes it an ideal material for use in vacuum furnaces, where it helps to reduce heat loss and improve temperature uniformity.
Vacuum furnace with ceramic fiber liner has 2 working temperature range, one is 1200℃ max. Working temperature,which applies Cr2Al2Mo2 resistance wire coil heating elements and polycrystalline ceramic fiber liners; one is 1700℃ max. Working temperature, which applies Molybdenum Disilicide heating elements and polycrystalline ceramic fiber liners.
Vacuum furnaces with ceramic fiber lining are used in a variety of applications, including:
- Vacuum heat treatment
- Vacuum brazing
- Sintering
- Degassing
Furnace chamber adopts high-density light alumina ceramic fiber, stable structure, thermal shock performance and thermal stability;Good performance, low heat capacity, low thermal conductivity, energy saving of more than 50% compared with traditional silicon carbide furnace.
Applications
Vacuum furnaces lined with ceramic fiber are widely used in various industries for a range of applications, including:
- Heat Treatment:** Hardening, tempering, annealing
- Brazing:** Joining of metal components in a vacuum environment
- Sintering:** Bonding of powder materials under controlled temperature and pressure
- Degassing:** Removal of gases from materials, such as metals and ceramics
- High-temperature processing:** Vacuum furnaces enable precise temperature control and a clean, safe environment for processing materials at high temperatures
Features
KinTek vacuum furnaces offer precise temperature control, excellent temperature uniformity, and a wide range of applications for labs, universities, and any small-scale production application using industrial furnace models. Each standard and customized vacuum furnace offers the following features and benefits:
- Excellent temperature accuracy and uniformity
- Energy efficient ceramic fiber insulation
- Auto shut-off safety feature
These furnaces offer a number of advantages over traditional vacuum furnaces, including:
- No surface oxidation or discoloration
- Minimal distortion
- Flux free brazing
- Repeatable quality
- Clean, safe, quiet and efficient
Principle
The vacuum furnace with ceramic fiber lining uses a heating element made of resistance wire or molybdenum disilicide to heat the furnace chamber. The ceramic fiber lining insulates the furnace chamber, minimizing heat loss. The furnace is equipped with a vacuum pump that evacuates the air from the furnace chamber, creating a vacuum environment. This vacuum environment prevents the oxidation of the materials being heated and allows for precise temperature control. The furnace is also equipped with a temperature controller that regulates the temperature of the furnace chamber.
Advantages
- No surface oxidation or discoloration: The vacuum environment prevents oxygen from reaching the workpiece, eliminating oxidation and discoloration.
- Minimal distortion:The uniform heating and cooling rates minimize thermal stresses, reducing distortion.
- Flux free brazing:Vacuum furnaces allow for fluxless brazing, eliminating the need for post-brazing cleaning.
- Repeatable quality: The controlled atmosphere and precise temperature control ensure consistent and repeatable results.
- Clean, safe, quiet and efficient:Vacuum furnaces operate in a closed environment, minimizing noise and emissions. They also offer improved energy efficiency due to the reduced heat loss.
- Excellent heat insulating property:Polycrystalline ceramic fiber liners provide excellent thermal insulation, resulting in reduced heat loss and energy savings.
- Outstanding uniformity of temperature field:The ceramic fiber lining promotes uniform temperature distribution throughout the furnace chamber.
- High vacuum performance:Vacuum levels up to 6*10-3Pa ensure effective removal of gases and contaminants.
- Excellent vacuum pressure maintaining performance:** The low vacuum pressure rise rate (0.67Pa/h) maintains a stable vacuum environment.
- PID programmable microprocessor temperature control system:Precise temperature control ensures accurate and reliable heating.
- Safety interlock system:Automatic power shut-off in case of door opening, over temperature, or sensor failure ensures safe operation.
Vacuum Furnace Safety Advantage
- Kindle Tech vacuum furnace owns over current protection, over temperature alarming function, furnace will turn off the power automatically
- Furnace build in thermal couple detecting function, furnace will stop heating and alarm will be on once broken or failure detected
- Power failure restarting function,furnace will resume the furnace heating program when power is incoming after failure

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
