control system

Heating element

The system adopts a short wave infrared heater with a power of 1.1~1.5um, which has high efficiency and does not directly contact the surface of objects. It does not need to pass through any medium and conducts high energy by releasing electromagnetic rays, achieving the goal of rapid heating.

Sealing system

Optional: Vacuum degree: ≤ 10Pa (mechanical pump) ≤ 3.5 * 10-3Pa (f molecular pump unit)

Pressure measurement and monitoring

Using a mechanical pressure gauge with shock-absorbing oil can prevent damage to the gauge pointer.

Gas supply system

Adopting float flow meter control, integrated with equipment for easy control, leak testing has been carried out before leaving the factory.

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 shall 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, for more precise and safe 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.When conducting heating experiments, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. 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. If the absolute pressure gauge reading is greater than 0.15MPa, the exhaust end valve must be immediately opened to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
