Vacuum atmosphere furnace needs to choose a suitable atmosphere for sintering

Different materials choose suitable atmosphere for sintering, which will help the sintering process, improve the degree of product densification, and obtain products with good performance. Vacuum atmosphere furnaces are commonly used in various atmospheres such as vacuum, hydrogen, oxygen, nitrogen, and inert gases (such as argon). For example, transparent alumina ceramics can be sintered in a hydrogen atmosphere, transparent ferroelectric ceramics can be sintered in an oxygen atmosphere, and nitride ceramics such as aluminum nitride can be sintered in a nitrogen atmosphere. Sometimes it is necessary to operate in a protective atmosphere in order to protect the sintering tuning.

Let’s take a look at the characteristics of the vacuum atmosphere furnace.

1. Control accuracy: ±1℃ Furnace temperature uniformity: ±1℃ (depending on the size of the heating chamber).

2. Convenient operation, programmable, PID auto-tuning, automatic heating, automatic heat preservation, automatic cooling, no need to be on duty; it can be equipped with computer communication through the computer to operate the electric furnace (start the electric furnace, stop the electric furnace, pause the heating, set the heating curve, and increase the temperature (Curve storage, historical curve, etc.), the software is free for details, please refer to: computer control system.

3. Fast heating up (temperature rise rate is adjustable from 1℃/h to 40℃/min).

4. Energy saving, the hearth of the vacuum atmosphere furnace is made of imported fiber, resistant to high temperature, rapid heat and cold

5. The furnace body has been exquisitely sprayed, corrosion-resistant and acid-alkali resistant, and the furnace body and the furnace are separated by air-cooled furnace wall temperature close to room temperature

6. Double circuit protection (over temperature, over pressure, over current, segment couple, power failure, etc.)

7. The furnace material is imported refractory materials, the vacuum atmosphere furnace has good heat preservation performance, high temperature resistance, and resistance to rapid cold and rapid heat.

8. Temperature category: 1200℃ 1400℃ 1600℃ 1700℃ 180O℃ five kinds

9. Furnace body sealing and water-cooling structure: Sealing parts: Sealing parts are made of silicone rubber ring (temperature resistance 260 degrees -350 degrees). Cooling structure: double-layer furnace shell, air-cooled + water-cooled.

The above are the characteristics of the vacuum atmosphere furnace. If you have more needs, please consult us.
