Why is the temperature rise of box furnace slow

High temperature electric furnace, as the name suggests, is a high-temperature electric furnace. Only such a high-temperature furnace can burn and melt hard things. However, have you ever encountered a situation where the temperature of the electric furnace can not rise and the ablation cannot be carried out. In case of such a situation, many people will be at a loss. Waiting for technicians to come for maintenance wastes working time and is also a loss to the economy. In fact, you can first master the general reasons for the slow temperature rise of the box furnace, and then check and analyze them one by one.

Next, the box furnace manufacturer will introduce the common reasons why the temperature cannot rise:
1. the voltage of the whole circuit is too low to meet the rated voltage standard of the box furnace.
2. the electric heating element has a short circuit locally, and the resistance value does not meet the design requirements.
3. the sealing performance of the box furnace is too poor.
4. the unbalance value of three-phase current exceeds 20%.
5. the protective gas supply panel is too large.
6. the hot spot position of thermocouple is not representative.
