1500 degree silicon carbon rod box muffle furnace

The box muffle furnace produced by our company has beautiful appearance, fine workmanship, and scientific and reasonable double-layer liner structure; the furnace is made of new insulation materials for energy saving and environmental protection; this box furnace uses silicon carbon rods as heating elements, which have been pre-burned before leaving the factory, and will not volatilize and discolor to pollute the heated materials; the maximum temperature can reach 1500℃, which can meet most experimental requirements and is economical. This box furnace is completely comparable to imported similar box furnaces. Our company's series of box furnaces have mature technology, fine workmanship, stable and reliable product quality, and are the best cost-effective box furnaces at home and abroad. At present, it has won bids for many times in the bidding and procurement of box furnaces in many scientific research institutions and colleges and universities, and has been well received in actual use. 

Scope of application:

Mainly used for high-temperature sintering, material annealing, composition analysis and other experiments under air atmosphere.

Technical parameters：

1500 degree box furnace is very practical in experiments such as high temperature sintering, material annealing and composition analysis under air atmosphere. The following are its main applications and operation steps:

Main application：

High temperature sintering: used for sintering of ceramics, metals and composite materials to ensure the density and mechanical properties of the materials.

Material annealing: used for annealing of metals and alloys to improve the ductility and toughness of the materials.

Composition analysis: used for high temperature treatment of samples for composition analysis and material research.

Operation steps

Preparation:

Make sure the furnace is clean and free of debris.

Set the temperature curve according to the experimental requirements. Usually, multiple time-temperature curves can be preset.

Loading samples:

Place the samples evenly in the furnace.

Close the furnace door to ensure good sealing.

Set parameters:

Set the required temperature and time parameters through the control panel or touch screen.

Start the heating program and gradually increase the temperature to the target temperature. The recommended heating rate is 10℃/minute.

Sintering/annealing process:

Keep at the target temperature for a certain time and adjust the insulation time according to the material and process requirements.

After completion, gradually cool down to room temperature to avoid damage to the sample due to rapid cooling.

Take out the sample:

After confirming that the furnace temperature has dropped to a safe range, open the furnace door to take out the sample.

Perform subsequent processing or analysis.

Equipment features:

High temperature performance: The maximum temperature can reach 1500℃, and the working temperature is generally below 1400℃.

Temperature control accuracy: Intelligent PID control, temperature control accuracy can reach ±1℃.

Safety function: It has over-temperature alarm, over-current protection and broken couple prompt functions.

When using a 1500-degree box furnace, follow the following precautions to ensure safety and long life of the equipment:

Safety precautions:

Protective equipment: Wear high-temperature resistant gloves, protective glasses and laboratory coats during operation to prevent high-temperature burns.

Good ventilation: Ensure that the laboratory is well ventilated to avoid the accumulation of harmful gases.

Stay away from flammable materials: Do not place flammable and explosive items around the equipment.

Emergency measures: Familiarize yourself with the location and use of emergency shutdown equipment and fire extinguishers.

Operation precautions

Preheating and cooling:

Gradually heat up and cool down to avoid damage to the furnace or samples caused by sudden temperature changes.

The recommended heating rate is 10℃/min and the cooling rate is 5℃/min.

Sample loading:

The sample should be evenly distributed to avoid excessive accumulation.

Use a crucible or tray made of high temperature resistant material.

Temperature control:

Set a reasonable temperature and time curve to avoid over-temperature operation.

Calibrate the temperature sensor regularly to ensure temperature control accuracy.

Maintenance:

Clean the furnace regularly to remove residues.

Check the heating elements and electrical connections to ensure that they are not damaged or loose.

Recording and monitoring:

Record the temperature and time parameters of each use for easy tracking and analysis.

Monitor the operating status of the equipment in real time and deal with abnormalities in time.

Equipment maintenance:

Regular inspection: Check the electrical system and heating elements of the equipment once a month to ensure normal operation.

Cleaning and maintenance: Clean the furnace after use to avoid residues affecting the next use.

Replacement of parts: Replace aging or damaged parts regularly according to the frequency of use and equipment condition.

Common problems and solutions

Unstable temperature:

Check whether the temperature sensor is working properly.

Confirm that the temperature control system is set correctly.

Damaged heating element:

Turn off the equipment and replace the heating element after cooling.

Check if the electrical connection is loose or damaged.

Cracks in the furnace:

Minor cracks can be repaired with high temperature repair materials.

Severe cracks require replacement of the furnace.
