What are the common temperatures for muffle furnaces?

Muffle furnace is a commonly used heating equipment, and its common temperature range depends on specific process requirements and material characteristics. Generally speaking, the temperature range of a muffle furnace can range from several hundred degrees Celsius to several thousand degrees Celsius. The following is a summary of common temperatures for muffle furnaces:
1. Classified by rated temperature
Muffle furnace below 1000 ℃: suitable for heating needs at lower temperatures.
1000~1300 ℃ muffle furnace: including models such as 1100 ℃, 1200 ℃, 1300 ℃, etc. The silicon carbon rod muffle furnace is usually within this temperature range.
Muffle furnaces above 1600 ℃: including models such as 1600 ℃, 1700 ℃, 1800 ℃, etc., silicon molybdenum rod Muffle furnaces can usually reach this high temperature range.
2. Temperature in specific application scenarios
Melting: For some samples that require high-temperature melting, the temperature of the muffle furnace may need to reach 1000 ℃ or even higher.
Annealing: During the annealing process, the temperature of the muffle furnace usually needs to be adjusted according to the type and thickness of the material, usually between a few hundred degrees Celsius and over a thousand degrees Celsius.
For other heat treatment applications such as quenching and tempering, the temperature of the muffle furnace also needs to be adjusted according to specific process requirements.
3. Precautions
Temperature control: Muffle furnaces are usually equipped with precise temperature control systems that can set and adjust the temperature as needed.
Temperature uniformity: In order to ensure the heating effect, the temperature inside the muffle furnace needs to be kept uniform. Therefore, when choosing a muffle furnace, attention should be paid to its temperature uniformity index.
High temperature protection: As the muffle furnace needs to operate at high temperatures, corresponding protective measures need to be taken, such as using high-temperature resistant materials and setting up over temperature alarms.
In summary, the common temperature range of muffle furnaces is very wide, ranging from several hundred degrees Celsius to several thousand degrees Celsius. The specific temperature depends on the requirements for heating the sample and the model and specifications of the selected muffle furnace. When using a muffle furnace, it is necessary to select the appropriate temperature range based on specific process requirements and material properties, and ensure that temperature control and uniformity meet the requirements.
