1. The material will roll radial and axial under the rotating pendulum vibration of the reaction chamber to ensure uniform heating of the material and adequate contact with the gas to prevent overburning and entraining caused by static sintering;

2. High purity Al2O3 fiber refractory insulation material, excellent insulation effect, reduce the power consumption of equipment;

3. Adopt advanced dynamic sealing device to ensure that the equipment can be used in vacuum and atmosphere;

4. The product uses automatic control mode, equipped with 7-inch touch screen real-time tracking display device status;

5. The furnace body can be tilted to -5-30°, which is convenient for customers to discharge materials.

Pressure measurement and monitoring

The mechanical pressure gauge with damping oil is used to produce damping when the pressure fluctuates and reduce the pointer to swing back and forth.

Gas supply system

Float flowmeter is used to control the flow rate of gas, integrated with the equipment, and the leakage test has been carried out before leaving the factory.

Cautions

1. When the furnace temperature of the equipment is greater than or equal to 300℃, it is forbidden to open the furnace to avoid injury;

2. When the equipment is in use, the pressure in the furnace tube shall not exceed 0.125MPa (absolute pressure) to prevent damage to the equipment caused by excessive pressure;

3. When used in vacuum, the operating temperature of the equipment shall not exceed 800℃.


4. The internal pressure of the gas supply cylinder is high, and when the gas is fed into the furnace tube, the pressure reducing valve must be installed on the cylinder. It is recommended to choose a small pressure reducing valve for test, and the measuring range of the valve is 0.01MPa-0.15MPa, which will be more accurate and safe in use.

5. When the temperature of the furnace body is higher than 1000℃, the furnace tube can not be in a vacuum state, the pressure in the furnace tube and atmospheric pressure, maintain in the state of atmospheric pressure;

6. Long-term use temperature of high purity quartz pipe ≦1100℃

7. During the heating experiment, it is not recommended to close the suction valve and intake valve at the flange end of the furnace tube. If it is necessary to close the air valve to heat the sample, it is necessary to always pay attention to the indicator of the pressure gauge. If the absolute pressure gauge reading is greater than 0.15MPa, the exhaust valve must be opened immediately to prevent accidents (such as furnace pipe rupture, flanges flying out, etc.).


8. The device is recommended to handle micron powder or granular sample, and it is not recommended to use this product for nano powder;

4. When used in vacuum, the operating temperature of the equipment shall not exceed 800℃.
