FAQ 

Q1: Can this sintering furnace process corrosive or flammable gases?

A: Yes. However, special requirements must be specified when ordering. The furnace can be equipped with explosion-proof and corrosion-resistant systems, safety valves, and corresponding gas leakage alarm devices.

Q2: How does the furnace prevent contamination during high-purity catalyst sintering?

A: The furnace chamber uses high-purity alumina fiber materials, which are non-shedding and have low volatilization characteristics. High-purity quartz tubes or alumina ceramic tubes can also be selected to isolate materials and prevent cross-contamination.

Q3: What is the typical heating rate of the furnace?

A: The recommended heating rate is 5–10℃/min, and the maximum heating rate can reach 20℃/min depending on the furnace model and material characteristics. Excessive heating rates may affect furnace service life.

Q4: How are exhaust gases treated during furnace operation?

A: The equipment is equipped with a dedicated exhaust outlet. According to the composition of gases generated during catalyst calcination, such as NOx and SO₂, optional treatment systems such as acid mist scrubbers or activated carbon adsorption devices can be installed.

Q5: What are the environmental requirements for equipment installation?

A: The equipment should be installed indoors in a well-ventilated area with a level floor and independent electrical protection. If atmosphere control or vacuum functions are required, gas cylinders and cooling water supply (or a water chiller) should be prepared in advance.
