Why the box type furnace heats up slowly

Time：2022-11-29

High temperature electric furnace, as its name implies, is a furnace with high temperature and electric burning. Only such a high temperature furnace can burn and melt hard things. However, have you ever encountered the situation that the temperature of the electric furnace is always unable to rise and the ablation work cannot be carried out. In case of such a situation, many people are at a loss, waiting for technicians to come and repair, wasting working time, which is also a loss to the economy. In fact, you can first understand the general reasons for the slow temperature rise of the box type furnace, and then check and analyze one by one. Next, the manufacturer of the box type furnace 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 type furnace.
2. The electric heating element has local short circuit, and the resistance value does not meet the design requirements.
3. The airtightness of the box type furnace is too poor.
4. The unbalance value of three-phase current exceeds 20%.
5. The protective gas supply panel is too large.
6. Thermocouple hot spot position is unrepresentative.
