Tube furnace is a common sintering equipment in laboratory. What are the types of tubular furnaces?

1. According to the temperature and heating elements, there are 1200 ℃ resistance wire tube furnace, 1400 ℃ silicon carbide rod tube furnace and 1600 ℃ silicon molybdenum rod tube furnace.

2. According to the material of furnace tube, there are quartz tube furnace, stainless steel tube furnace and corundum tube furnace.

3. According to the structure of heating part, there are open tubular furnace and integrated tubular furnace.

4. According to the furnace structure, there are horizontal tube furnace, vertical (vertical) tube furnace, multi station tube furnace, inclined tube furnace, rotary tube furnace and sliding rail tube furnace.

5. According to the temperature control area, it can be divided into single temperature zone tubular furnace and multi temperature zone tubular furnace (for example, double temperature zone tubular furnace, three temperature zone tubular furnace, five temperature zone tubular furnace, etc.)

7. It can also be divided into high vacuum tubular furnace and low vacuum tubular furnace according to vacuum degree

8. Other can also be used: such as rapid annealing tubular furnace, CVD tubular furnace, PECVD tubular furnace, etc.

Tubular furnace can provide electric furnace with completely sealed high temperature environment, which can ventilate and vacuum. Tube furnace is a more precise heating equipment. It is very important and necessary to master the safe operation rules and regular maintenance of tubular furnace.

Safe operation of tubular atmosphere furnace:

1. Develop a "vacuum furnace safety manual" for relevant staff to understand.

2. Operators should be trained before use.

3. Appoint a safety officer and master all safety regulations

4. Keep the work area clean and safe.

5. When operating and maintaining the equipment, the staff should use labor protection equipment, such as safety eyes, shoes, gloves, safety helmet, mask, breathing mask, etc.

6. Post the name and telephone number of the emergency contact person, and the emergency telephone number of the hospital.

Maintenance of tubular atmosphere furnace:

1. Regular equipment maintenance can help the vacuum furnace to use more effectively and reduce maintenance costs.

2. Develop daily, weekly and monthly inspection procedures, design inspection forms and make records. Only after inspection can the production equipment be used.
