1. Do not place the unit on an uneven or vibrating surface, as this may cause the unit to become unstable and tip over. 2. Do not place flammable or explosive items near the furnace, as this may cause an explosion. 3. Do not drop metal objects such as screws and washers into the unit, as this may cause a short circuit or fire. 4. Do not place the unit in a location susceptible to water splashing. If water enters the unit, it may cause a fire or electric shock.

During operation, a high temperature box furnace may experience abnormal furnace pressure, seriously affecting normal operation. Symptoms of abnormal furnace pressure include unstable combustion, a smaller or larger flame, and increased noise. There are many causes, and this article describes some common solutions.

1. Understand the temperature tolerance range of the material. Different materials have different high-temperature resistance properties. Excessively high temperatures can cause deformation, melting, or damage. Therefore, when setting the temperature of a high-temperature box furnace, you should refer to the material's temperature tolerance range to ensure that the selected temperature does not exceed this range.

Excessively rapid heating rates can lead to uneven temperatures within the material, causing uneven changes in the material's microstructure and affecting the accuracy of the experimental structure. For example, in the heat treatment of metal materials, excessively rapid heating rates can cause cracks or deformation, affecting the material's performance test results.
