Factory environment

1. Indoor use

2. Environmental temperature within ±5-45℃ range.

3. Relative ambient temperature does not exceed 85%.

4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the stove.

Safety Protection

1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to dry the furnace to prevent cracking of the furnace chamber.

2. Keep the furnace clean regularly and check the electrical connections for good contact.

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 melted metals into the furnace.

4. During the process, the temperature should generally not exceed 300℃ and the heating rate should be moderate, as the furnace chamber is cold at the beginning and requires a significant amount of heat absorption.

After-sales Service

1. We commit to resolving any technical inquiries from our clients within one hour.

2. We promise to issue the test results within 1 working day for equipment returned for repair, 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.

Friendly 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 shortages 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, so flammable or explosive gases cannot be introduced.

6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. These can be repaired using an alumina coating.

The equipment operates with voltage but no current.
