Overview
This SLQ1200-50 atmosphere furnace is specially designed for sintering or annealing materials in an atmosphere or inert gas environment, with a maximum Operating temperature of 1200 ° C. It uses aluminum oxide fiber furnace and alloy wire heating elements, and the top sealing plate of the furnace body integrates a chilled down water pipe to ensure sealing. It is ideal for processing materials such as Pottery and porcelain that need to be sintered in inert or reducing gas environments.
Features
1. Operating temperature up to 1200 ℃, Temperature range 1000 ℃.
2. Using aluminum oxide fiber furnace, the size is 500 * 400 * 400mm, and the volume is 36L.
3. Using alloy resistance wire as heating element, Heating power is 15KW.
4. High temperature control accuracy, up to +/- 1 ℃.
5. Equipped with double chill down system: air cooling and water cooling.
6. Integrated gas control system with flow meters (N2 and H2) and mechanical Vacuumpump.
7. The sealing plate on the top of the furnace body has a built-in chilled down water pipe to ensure good sealing performance during work.
8. Support inert gas (such as N2) and reducing gas (such as H2) environment.
Principle
The atmosphere furnace generates heat through an internal alloy resistance wire heating element to heat the material in the aluminum oxide fiber furnace. The system precisely monitors the temperature in the furnace through a K-type Thermocouple, and the control system realizes precise temperature adjustment. During operation, inert or reducing gases can be introduced through the gas control system, and the mechanical Vacuumpump and sealing structure (including water-cooled sealing plate) can be used to establish and maintain the required atmosphere environment, so as to meet the sintering or annealing process requirements of the material in a specific atmosphere.
Applications
Pottery and porcelain materials sintering, material annealing, materials that need to be treated in an inert gas environment, materials that need to be treated in a reducing gas environment, preparatory
Standards
The data did not mention specific compliance criteria.
Steps
1. Check whether the equipment power supply (AC380V), chilled down water (water cooler flow rate 16L/min) and gas connection are normal.
2. Put the material to be treated into the furnace (size 500 * 400 * 400mm).
3. Close the furnace door and ensure sealing.
4. Vacuum the furnace using a mechanical Vacuumpump as needed.
5. Pass the required gas (such as N2 or H2) through the gas flow meter, and adjust the air pressure to 0.01-0 Mpa range.
6. Set the target temperature (up to 1200 ° C) and heating rate (≤ 10 ° C/min), and start the heating program.
7. After the sintering or annealing process, cool down according to the program, or use air/water cooling system to assist in cooling down.
8. After the furnace temperature drops to a safe range, turn off the gas and power sources and remove the sample.
Notice
The power supply of the equipment is AC380V, and it is necessary to ensure that the power supply meets the requirements and is safely grounded.
When introducing reducing gases such as hydrogen (H2), special attention should be paid to the safety of operation to prevent leakage.
• Before running, make sure that the chilled down water system (water cooler) works normally and the flow rate is not less than 16L/min to prevent the sealing parts from overheating.
• The maximum temperature in the furnace shall not exceed 1200 ° C, and the heating rate is recommended not to exceed 10 ° C/min.
• During operation, the pressure in the furnace should be maintained within the set range of 0.01-0 Mpa.
Before taking the sample, make sure that the furnace temperature has dropped to a safe range and turn off the gas source.
• Regularly check the sealing of the furnace body and each connecting pipeline to ensure no leakage.
