A high-temperature oven, also known as a high-temperature drying oven or heat treatment oven, is an experimental equipment used for drying, curing, aging, baking, and heat treatment processes at higher temperatures. It is widely used in industrial production, laboratory research, and quality control fields.

The working principle of a high-temperature oven is to convert electrical energy into thermal energy through electric heating elements, and then transfer the heat to the air in the studio through a circulating fan, so that the temperature inside the studio reaches the required high temperature. An insulation layer is usually installed inside the oven to reduce heat loss, improve heating efficiency, and protect the safety of external personnel.
