Product Introduction
High-temperature vacuum furnace is energy-saving, environmentally friendly, and aesthetically pleasing. The outer shell is made of cold-rolled steel plate, processed by advanced CNC machine tools, and finished with luxurious and beautiful dual-color imported epoxy powder electrostatic spraying technology. It is resistant to high temperatures and corrosion, featuring heating elements and a wind-cooling system between the double-layer furnace shells for rapid temperature drop. The furnace boasts even temperature distribution, low surface temperature of the furnace body, fast heating and cooling rates, and energy-saving advantages. The furnace chamber is constructed from imported composite alumina fiber material using CNC technology, offering strong resistance to thermal shock, excellent corrosion resistance, no collapse, crystallization, or slagging, and no pollution, with a long service life. The control system utilizes microcomputer artificial intelligence adjustment technology, featuring PID regulation, automatic control, self-tuning functions, multi-step program programming, and the ability to create various heating, holding, and cooling programs with high temperature control accuracy. Integrated module silicon-controlled rectifier control, phase-shifting triggering, and a protection system with independent over-temperature, over-pressure, over-flow, leakage, and short-circuit protection. The degree of automation is high, and all indicators have reached advanced levels.

Special Note
Factory environment | 1. Indoor use 2. Environmental temperature is within ±5-45℃ range. 3. The relative humidity of the surrounding environment should not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulate corrosive gases around the stove. |
Safety Protection | 1. When initially using or resuming use after a long period of disuse, the furnace must be dried out to prevent cracking of the furnace chamber. 2. Keep clean and regularly check that the electric furnace wiring is well-connected. 3. Do not exceed the rated temperature when using the electric furnace to prevent damage to the heating elements. It is strictly prohibited to pour flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the heating rate should be moderate. This is because, when heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |
After-sales service | We commit to resolving any technical inquiries from our clients within one hour. 2. We promise to issue the test results for equipment returned for repair within 1 working day, complete the repair within 3 working days, and handle special materials on a case-by-case basis. 3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendship Reminder | Do not operate the equipment at the rated temperature for extended periods to ensure its normal service life. 2. Carefully count and verify the quantity of goods and accessories upon receipt to avoid any inconvenience caused by under shipments or omissions. 3. To extend the lifespan of the instrument, we recommend that the heating and cooling rates do not exceed 10℃/min. Cooling rate should not exceed 5℃/min. 5. This furnace does not have a vacuum-sealed structure, therefore it is not suitable for introducing flammable or explosive gases. 6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. These can be repaired using an alumina coating. |
