Safety Protection | 1. When an electric furnace is first used or after a long period of disuse, it must be baked to prevent the furnace chamber from cracking. Keep clean regularly and check if the electrical furnace wiring is properly connected. 3. When using the electric furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is strictly 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, as the furnace is cold at the beginning and requires a significant amount of heat to be absorbed. |
