Equipment Introduction:

Vertical quenching tube furnace: High quality insulation material is composed of vacuum formed fiberboard, which has low heat storage and low thermal conductivity, thereby reducing equipment energy consumption and shortening heating time. By configuring different inflation kits, it can operate under non flammable or flammable protective or reactive gas conditions or in vacuum. Electric rotary release structure, safer quenching, and more stable structure.

Equipment features:
1. MoSi2 heating element suspension installation, easy to replace;
2. Vacuum ceramic fiber board forms insulation material;
3. RHTV type tube furnace for vertical operation, with bracket;
4. B-type thermocouple;
5. The power regulation unit is equipped with a low-voltage transformer and a thyristor regulator;
6. Temperature selection limiter, used for over temperature protection of the furnace and goods;
7. The switch equipment with a controller is separated from the kiln and installed in a separate vertical cabinet;
8. Electric rotary release structure, safer quenching, and more stable structure.

Pressure measurement and monitoring

Using a mechanical pressure gauge, the outer shell of the gauge is an airtight structure, which can effectively protect the internal components from environmental impact and debris intrusion, and has strong corrosion and high temperature resistance.

Gas supply system

The gas flow rate is controlled by a float flowmeter, integrated with the equipment, and leak testing has been carried out before leaving the factory.

After reaching the set temperature, the release can be carried out as needed, and the entire release process can be clearly seen through the observation port;

Equipment usage precautions

1. When the furnace temperature of the equipment is ≥ 300 ℃, it is prohibited to open the furnace to avoid injury;
2. When using the equipment, the pressure inside the furnace tube should not exceed 0.125MPa (absolute pressure) to prevent equipment damage caused by excessive pressure;
3. When used under vacuum, the operating temperature of the equipment shall not exceed 800 ℃.
4. The internal pressure of the gas supply steel cylinder is relatively high. When gas is introduced into the furnace tube, a pressure reducing valve must be installed on the cylinder. It is recommended to purchase a small pressure reducing valve for testing, with a range of 0.01MPa-0.15MPa, which will be more precise and safe to use.
5. When the temperature of the furnace body exceeds 1000 ℃, the furnace tube cannot be in a vacuum state, and the air pressure inside the furnace tube must be equivalent to atmospheric pressure and maintained at atmospheric pressure;
6. Long term use temperature of high-purity quartz tube ≤ 1100 ℃
7. It is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube during heating experiments. If it is necessary to close the gas valve to heat the sample, it is necessary to always pay attention to the reading on the pressure gauge. The absolute pressure gauge reading should not exceed 0.15MPa. The exhaust end valve must be immediately opened to prevent accidents (such as furnace tube rupture, flange flying out, etc.).
