Factory environment | 1. Indoor use 2. Environmental temperature is within ±5-45°C range. 3. Relative ambient temperature does 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 using an electric furnace for the first time or after a long period of disuse, it must be seasoned to prevent the furnace chamber from cracking. Keep clean regularly and check the electrical furnace wiring for good contact. 3. When using the electric furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour any flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, when heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |

To extend the service life of the instrument, we recommend that the heating and cooling rates not exceed 10℃/min. 4. The 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. Repair can be made using an alumina coating. |
