Atmosphere tube furnace
The main functions and characteristics of Nuotai Atmosphere Tube Furnace:

1. The furnace adopts imported alumina polycrystalline fiber material, which has good insulation performance, durability and high performance. Efficiency and energy saving.

2. The heating element adopts imported high-quality alloy wire, which is durable and the temperature can reach 1200℃.

3. It adopts a double-layer shell structure, combined with thermal induction technology, and is equipped with an air cooling system to quickly cool the surface temperature of the furnace body.

4. The RK quick flange connection is adopted, which reduces the possibility of damage to the heating tube, and makes it easier and faster to take and discharge materials.

5. The top-opening furnace cover design can observe the heated materials in real time, and can quickly cool down to meet the experimental needs of rapid cooling and heating of materials;

6. Intelligent PID high-precision control, self-tuning function, 30-segment programmable control, 30-segment heating and cooling program can be set, and no power loss is realized.

7. Reserve the vacuum and gas path quick interface to cooperate with our company's vacuum and gas mixing system; it can meet the needs of users to conduct experiments under different vacuum conditions and different atmosphere conditions.

8. Reserve 485 conversion interface, through our company's special software, and computer interconnection, can realize single or multiple electric furnaces remote control, real-time tracking, historical records, output reports and other functions;

9. It has safe operation functions such as power-on and power-off, over-temperature alarm, and leakage protection.

Why is the heating furnace divided into a radiation chamber and a convection chamber?

Answer: 1) The radiation chamber of the heating furnace has two functions: one is to be a combustion chamber; the other is to transfer the flame, high-temperature flue gas and the radiation heat of the furnace wall from the burner to the medium through the furnace tube. This kind of stove mainly relies on radiant indoor

A small part of the radiant heat transfer depends on the convection of the convection chamber, which only accounts for about 10% of the entire heat transfer.

2) The main function of the convection chamber is: the high temperature flue gas in the convection chamber transfers heat to the medium in the furnace tube in a convection manner. In the convection chamber, there is also a small part of the flue gas and the radiation heat transfer of the furnace wall. If one heats up

If the furnace has only a radiant chamber without a convection chamber, the exhaust gas temperature will increase, resulting in energy waste, increased operating costs, and reduced economic benefits. For this reason, when designing a heating furnace, a convection chamber is usually set up for charging.

Separately recover the heat in the flue gas.
