Introduction to Vacuum Atmosphere Circulating Annealing Furnace Equipment:

Equipment features:
1. Sliding rail structure: The main body of the equipment is equipped with a long track, and the furnace body can slide smoothly along the track. This not only facilitates the loading and unloading of workpieces, but also enables rapid cooling after heat treatment, shortening the process cycle.
2. Rapid annealing capability: Due to its design allowing the workpiece to quickly enter and exit the heating zone, it can achieve rapid heating and cooling, meeting the special annealing process requirements of some material processing, such as rapid annealing (RTP).
3. Continuous production: suitable for continuous production, improving production efficiency, continuously passing workpieces in the furnace, reducing waiting time, and increasing unit time output.
4. Temperature control: With precise temperature control, it ensures the uniformity of material heating and meets the heat treatment requirements of different materials.
5. Atmosphere control: controllable atmosphere, capable of vacuuming and filling with specific gases such as nitrogen, hydrogen, argon, etc., to meet the heat treatment needs of different materials.
6. Safety features safety design protection, including over temperature protection, pressure control, and emergency shutdown of the furnace body to ensure safe operation during use.

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.

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.).
