What is the long-term use temperature of the high-temperature furnace?

Different types of high-temperature furnaces have different temperatures for long-term use. It is generally recommended that the temperature for long-term use be lower than 50 degrees of the rated temperature. Do not exceed the rated temperature to avoid burning the heating element.

The rated temperature of the high-temperature furnace is 1800℃, the atmosphere in the furnace is air, and the common temperature is 1700℃

The rated temperature of the high-temperature furnace is 1700℃, the atmosphere in the furnace is nitrogen, and the common temperature is 1600℃

The rated temperature of the high-temperature furnace is 1700℃, the atmosphere in the furnace is hydrogen, and the common temperature is 1100℃-1450℃
