Heating element

silicon carbide rods

Furnace body

The furnace body is machined using CNC machine tools, and undergoes polishing, grinding, pickling, phosphating, powder coating, and high-temperature baking. It features a two-tone design, a novel and attractive appearance, and possesses advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning.

Furnace body structure

The electric furnace body adopts a double-layer air-cooled structure. Effective air-cooling guide baffles ensure overall cold air circulation within the furnace shell, ultimately cooling the conductive plates of the heating elements before they are discharged from the furnace body, thus preventing high-temperature oxidation of the conductive plates and guaranteeing a good working environment.

journey

Itinerary is adjustable

Pressure holding

Equipped with an imported solenoid valve, it maintains pressure very well.

Furnace mouth combination

The furnace opening has 3-4 layers of tapered steps for soft sealing, and elastic high-temperature sealing strips are arranged on the steps to effectively absorb the expansion of the refractory material between the furnace opening and the charging platform.

Material grinding tools

thermal insulation materials

The system employs a three-layer insulation system: alumina fiber cotton, alumina fiber board, and alumina polycrystalline fiber board. This results in energy savings of over 80% compared to older electric furnaces.

Refractory materials

High-purity alumina zirconium-containing fiberboard

Furnace body outer shell

temperature

For long-term use without shutting down the furnace, the outer casing temperature should be less than 45 degrees Celsius.

Protect

The system employs an integrated modular control unit, ensuring accurate control precision. It also features dual-loop control and dual-loop protection, providing protection against overshoot, over-adjustment, under-adjustment, thermocouple breakage, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start.

control

Employing closed-loop technology with thyristor module trigger control, phase-shift trigger control, or zero-crossing triggering, the output voltage, current, or power is continuously adjustable, exhibiting constant voltage, constant current, or constant power characteristics. The current loop is the inner loop, and the voltage loop is the outer loop. When a sudden load is applied or the load current exceeds the current limit, the output current of the voltage regulator is limited to the rated current range, ensuring normal operation of the output and the voltage regulator. Simultaneously, the voltage loop also participates in regulation, limiting the output current of the voltage regulator to the rated current range, maintaining constant output current and voltage with sufficient adjustment margin. This protects the heating elements from excessive current and voltage surges, achieving safe, reliable, and precise control.

Warranty coverage and period

The electric furnace comes with a one-year free warranty, but the heating element is not covered by the warranty.

Precautions

1. To avoid affecting the lifespan of the electric furnace, we recommend a maximum heating and cooling rate of 10-20℃/min (rapid heating at high temperatures will shorten the lifespan of the heating element).

2. After a period of use, minor cracks may appear in the furnace chamber of this hot press. This is normal and will not affect its use. It can be repaired with an alumina coating.

3. It is not recommended to introduce corrosive gases. If you need to introduce highly corrosive gases such as S or Na, please inform us in advance so that we can perform special treatment on the furnace.

4. High-temperature solution must not leak onto the furnace bottom. To prevent this, a pad or alumina powder can be used for isolation.

5. The instrument should be placed in a well-ventilated, dry place.

Shipping Information

1. The electric furnace is packaged in three layers: first wrapped in foam paper, then wrapped in plastic film, and finally packed in a wooden crate.

2. Free domestic door-to-door delivery (free delivery within city limits)

3. We will be responsible for any damage that occurs during the transportation of the electric furnace.

4. Logistics methods: transportation by car, rail, ship (for foreign trade export), and air (for foreign trade export). For nearby locations, our company will arrange dedicated vehicles for transportation (packaging is wooden pallets and cardboard boxes).
