Overview
BOZHEN BZG-80-12 open vacuum tube furnace is a high temperature experimental equipment with double-decked shell structure. The furnace consists of a reversable upper furnace body and a fixed lower part, which is convenient for material pickup and observation. It uses quartz tube as furnace tube and is equipped with vacuum system, which is suitable for high temperature treatment and experiment of various materials.
Features
1. The gas connection adopts a quick connection flange structure, which is easy to operate.
2. The picking and placing of materials is simplified, and the gas path connection can be completed by using a card screen.
3. Cancel complex flange installations to reduce the risk of furnace tube damage.
4. Adopt double-decked shell structure, the inner layer is stainless steel, and the shell is carbon steel.
5. The heating furnace can be turned back 110 ° as a whole, which is convenient for picking and placing and observing materials.
6. The furnace adopts high-purity aluminum oxide fiber material, which saves 50% of energy and has a uniform temperature field.
7. The heating element adopts OCr27Al7Mo2 alloy resistance wire, which is located around the furnace and has high temperature uniformity.
8. Using quartz tube, both ends are sealed with stainless steel flanges.
9. Use K-type Thermocouple for temperature measurement.
10. Double-decked furnace shell is equipped with Air-Cooled system, which can quickly cool down, and the surface temperature of the furnace shell is less than 60 degrees.
11. The furnace tube is equipped with stainless steel sealing flange and silicone sealing ring, and a mechanical pressure gauge is installed.
12. The temperature control instrument uses PID mode to adjust the temperature, with a 30-stage program for temperature control.
Principle
The tube furnace is heated by alloy resistance wires located around the furnace, the temperature is monitored in real time by K-type Thermocouple, and the temperature is precisely adjusted and controlled by PID temperature control instrument. Flanges and silicone sealing rings are used at both ends of the furnace tube for sealing, which can be connected to a Vacuumpump to extract air, and heat treat the materials in the furnace tube at the set Vacuum Level and the programmed temperature.
Applications
Universities, research institutes, industrial and mining enterprises do powder roasting, Pottery and porcelain sintering, high temperature experiments, material treatment, mass testing.
Steps
1. Use the card screen to complete the quick connection of the gas path.
2. Put the material into the quartz furnace tube.
3. Set the required 30-segment program temperature control through the temperature control instrument Linear dispersion.
4. Start the equipment and start the heating and vacuum treatment process.
5. After the experiment, the Air-Cooled system can be used to assist in cooling.
6. After the furnace body is chilled down, turn over the upper furnace and take out the material.
Notice
When taking and placing materials, pay attention to the high temperature of the furnace to avoid burns.
• Ensure that the gas connection flange and sealing ring are installed correctly to ensure Vacuum Level.
• Follow the recommended heating rate (10 ° C to 15 ° C/min).
• When the equipment is running, the furnace shell surface temperature may still be high, do not touch.
• Regularly check the performance of the Vacuumpump and sealing system.
