1. The intelligent control instrument enables slope heating and cooling, with 30 segments of program settings.
2. The furnace chamber of alumina ceramic fiber and the ceramic fiber inner liner are resistant to extreme cold and heat without cracking or combustion.
3. The double-layer air-cooled furnace body reduces the surface temperature of the furnace body, ensuring greater stability and safety.
4. Safety protection functions include over-temperature protection, temperature deviation protection, open-couple indication, and the standard air circuit breaker is equipped.
5. The 304 stainless steel flange seal is corrosion-resistant, oxidation-resistant, and has strong sealing performance.
6. A variety of gases can be passed through, including all inert gases and mixed gases, such as nitrogen, oxygen, carbon monoxide, chlorine, etc.
7.Silicon Carbon Rods or Silicon Molybdenum Rods are used for heating, featuring high thermal conductivity, high-temperature resistance, and low deformation.

Working environment conditions:
1. The altitude must not exceed 1000m.
2. The ambient temperature should range from -10 to 75℃.
3. The average monthly relative humidity in the applicable region should not be greater than 85%.
4. There should be no conductive dust, explosive gases, or corrosive gases that can severely damage metals and insulation around the furnace.
5. There should be no significant vibration or jolt.

Precautions:
1. When operating the electric furnace, the furnace temperature must not exceed the rated temperature to avoid damaging the heating elements. It is strictly forbidden to directly pour various liquids and molten metals into the furnace chamber. Regularly remove iron filings and oxides from the furnace chamber to maintain its cleanliness.
2. Regularly inspect the electric furnace and check whether the contacts of each connection part of the temperature controller and the conductive system are in good condition.
3. Safety protection: Wear appropriate protective gear.
4. Careful handling: Handle with caution to avoid severe vibration and collision.
5. The properties of S-type and B-type thermocouples do not permit their application in environments with high hydrogen, high carbon, and high silicon contents, as they are susceptible to corrosion and damage.
6. For furnaces with quartz tubes as the material, when utilized for the first time or after a prolonged period of non-use, they should be baked at approximately 200°C for 2 hours, followed by another 2 hours at around 300°C prior to operation, in order to avoid cracking of the furnace chamber.
7. For furnaces with corundum tubes, when employed for the first time or after an extended period of disuse, they should be baked at around 300 - 400°C for 5 - 6 hours to prevent cracking of the furnace chamber.
8. The recommended heating rate for corundum tubes is 10°C/min when the temperature is below 1000°C; no more than 5°C/min when the temperature is between 1000 - 1500°C; and no more than 2°C/min when the temperature is above 1500°C. Otherwise, it may cause damage to the furnace chamber, heating elements, and tubes.
9. Corundum tubes should not be operated under negative pressure at temperatures exceeding 1000°C, and quartz tubes should not be operated under negative pressure at temperatures exceeding 800°C.
10. The furnace body adopts silicon molybdenum rods as the heating elements and is not suitable for prolonged operation within the temperature range of 400 - 700°C. Otherwise, low-temperature oxidation of the silicon molybdenum rods may occur, resulting in component damage.
