Q1. What are the working dimensions of this rotary burnout oven? Is customization supported?

A: The internal standard dimensions of this rotary oven are 700mm (W) x 700mm (D) x 700mm (H). Yes, we support size customization based on your production needs.

Q2. How many flasks can this rotary burnout oven load at one time?

A: The standard-sized rotary oven is equipped with 2 layers of rotating trays. With reasonable layout, it can simultaneously load up to 36 pcs of standard φ4 x 11-inch flasks, making it ideal for centralized dewaxing and firing of small to medium batch jewelry casting.

Q3. What is the maximum working temperature this rotary burnout oven can reach?

A: The maximum design temperature of this equipment can reach 1000°C, fully meeting the requirements for complete dewaxing and high-temperature firing of plaster molds for various precious metal casting. It is equipped with a temperature protection system; once the temperature exceeds the set point, the power will automatically cut off, ensuring the machine and castings are not damaged.

Q4. What is the heating method and working principle of this rotary burnout oven?

A: This rotary oven uses electric resistance heating. The furnace chamber is lined with heating elements on three sides to ensure even heating.
Working Principle: It provides precise temperature control through multi-zone electric radiant heating while driving the loaded part carrier to rotate at a constant speed, achieving dynamic and uniform heating of the parts. The melted wax flows smoothly out of the oven through a dedicated wax channel, preventing mold shell cracking due to wax expansion.

Q5. Is the rotation speed of the turntable adjustable during the dewaxing process?

A: Yes, the rotation speed is adjustable. The equipment is equipped with a speed-controllable rotation mechanism. Users can set the optimal rotation speed according to the size of different molds, wax characteristics, and process stages (e.g., low speed for dewaxing, medium to high speed for firing).

Q6. What are the main advantages of a rotary burnout oven compared to traditional static burnout ovens?

A: The main advantages lie in the process improvements brought by the rotation function:

• More Thorough and Safer Dewaxing: The centrifugal force generated by rotation effectively guides the melted wax to flow smoothly out of the flasks, significantly reducing the risk of mold cracking caused by thermal expansion of the wax.

• More Uniform Heating: Rotation ensures all sides of the flasks and molds are heated evenly, avoiding local hotspots or insufficient heating, resulting in mold shells with stable quality.

• Improved Efficiency and Consistency: Capable of processing a large number of molds at once with high process controllability, making it very suitable for standardized production.

Q7. Is your rotary oven easy to operate? Are there any other special designs?

A: Our rotary oven adopts PLC touchscreen control system, allowing customers to freely set parameters such as heating temperature and time, enabling automated operation. It features operation data logging, supporting continuous storage of run data and export of data log files. It is also designed with a secondary combustion function that re-burns exhaust gases inside the furnace, minimizing air pollution and making it an extremely environmentally friendly device.

Q8. What materials are the furnace chamber and rotation mechanism made of?

A: The furnace chamber is constructed from high-performance refractory ceramic fiber, offering good insulation and fast heating. The core rotating components are made of 310S stainless steel, ensuring long-term stable operation under high temperature and high load conditions.

Q9. What are the common process issues with the rotary burnout oven and their solutions?

A: The main common issues are:

• Mold Shell Cracking or Swelling: Usually caused by too rapid heating during the dewaxing stage. The solution is to use a gentler, low-temperature dewaxing curve and ensure the rotation function is properly activated.

• Castings with Porosity or Incomplete Metal Fill: This may be due to insufficient firing temperature or time, leaving the mold shell incompletely sintered or containing residual moisture. Check and ensure adequate firing temperature and holding time are reached.

• Residual Wax Ash After Dewaxing: Final firing temperature or time is insufficient. The temperature in the final firing stage should be increased and the holding time appropriately extended.

Q10. How is the daily maintenance and upkeep of the equipment performed?

A: You can follow the following suggestions for maintenance:

• Regular Cleaning: Clean up wax drips and other debris inside the furnace chamber promptly after it has cooled down.

• Inspect the Rotation Mechanism: Periodically check if the fixing screws of the rotating rack are loose, if the bearings operate smoothly, and add high-temperature lubricant as required.

• Clean Internal Dust: Due to prolonged use and environmental factors, dust may accumulate inside the machine and on the mainboard. Regularly use compressed air to clean the mainboard and internal dust. (Perform this only 30 minutes after turning off the main power switch to avoid electric shock hazard.)

• Check Seals and Heating Elements: Observe if the furnace door seal is intact. Check heating elements (e.g., silicon carbide rods, resistance wires) for signs of aging or damage.

• Exhaust System: Regularly check that the exhaust pipes are clear and unobstructed.
