Overview
BOZHEN BZG-60-12 open vacuum tube furnace is a high temperature experimental equipment with double-decked shell structure. The furnace is composed of a reversable upper furnace body and a lower part, which is convenient for material pickup and observation. It uses quartz tube as furnace tube, stainless steel flange sealing at both ends, combined with vacuum system, suitable for high temperature treatment and experiment of various materials.
Features
1. The gas circuit connection adopts a quick connection flange structure to simplify operation and reduce the risk of damage to the furnace tube installation.
2. Using double-decked shell structure, the inner layer is stainless steel, the shell is carbon steel, and equipped with Air-Cooled system, the surface temperature of the furnace shell can be quickly reduced to less than 60 degrees.
3. The heating furnace can be turned back 110 ° as a whole, which is convenient for picking and placing and observing materials.
4. The furnace adopts high-purity aluminum oxide fiber material, which saves 50% of energy and has a uniform temperature field.
5. The heating element adopts OCr27Al7Mo2 alloy resistance wire, which is arranged around the furnace to ensure temperature uniformity.
6. Adopt K-type Thermocouple temperature measurement, the temperature control instrument adopts PID adjustment, supports 30-stage program temperature control, and the thermostatic accuracy reaches +/- 1 ℃.
7. The furnace tube adopts quartz tube, the flange adopts double ring sealing technology, and the silicone O-ring can effectively improve the sealing performance. The Vacuum Level can reach -0.1MPa.
Principle
The tube furnace is heated by an alloy resistance wire surrounding the furnace, and the temperature is monitored in real time by a K-type Thermocouple, and the signal is fed back to the PID temperature control system for precise adjustment. The two ends of the furnace tube (quartz tube) are sealed with stainless steel flanges and silicone sealing rings to form an airtight space, which can be connected to the Vacuum pump to the required Vacuum Level. The double-decked Air-Cooled system between the furnace shells accelerates heat dissipation and ensures the safety of the equipment surface temperature.
Applications
Universities, research institutes, industrial and mining enterprises do powder roasting, Pottery and porcelain sintering, high temperature experiments, material treatment, mass testing.
Standards
The data did not mention specific compliance criteria.
Steps
1. Use the card screen to complete the quick connection of the gas path.
2. Put the experimental material into the furnace tube (quartz tube).
3. Set the required heating program (up to 30 stages) and target temperature through the control system.
4. Start the equipment and start the heating and temperature control process.
5. After the experiment, the Air-Cooled system can be used to accelerate the furnace body chilling down.
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 sealing.
• Follow the recommended heating rate (10 ° C to 15 ° C/min) to avoid damage to the furnace tube or sample due to excessive heating.
• Do not touch the high temperature furnace shell during equipment operation and chilling down.
• Regularly check the status of Vacuumpump, sealing ring and other components to ensure the normal operation of the equipment.
