Introduction to the selection method of electric furnace wire for four à moufle haute température

High-temperature muffle furnace is mainly used for high-temperature fusion of block and powder materials to obtain a variety of new formulas and new materials, and prepare samples for subsequent performance tests of new materials. It is used for experiments and production of frit glaze, glass solvent, enamel glaze binder for ceramics, glass, enamel abrasives and pigments and other enterprises and scientific research units. The operating temperature is also divided into various temperature ranges. Among them, the electric furnace wire is an important part of the road. Today, we will talk to you about its selection method.

The upper limit of the usable temperature of the electric furnace wire is a main performance indicator in the selection process of the high-temperature frit furnace. It is necessary to remind everyone that the use temperature of the electric furnace wire refers to the temperature of the element body surface during the operation of the electric furnace wire, not the electric heating The operating temperature that the equipment or heated object can reach.

In the design and selection of electric furnace wire, the following heating temperature can be measured according to the box-type electric furnace or heating object used. For example, when the electric furnace wire is used for boiler heating, the difference between the furnace temperature and the use temperature of the electric furnace wire is about 100 ℃ , If the heating temperature of the high-temperature muffle furnace wire exceeds the temperature that it can withstand, the oxidation process will be accelerated, the heat resistance performance will be reduced, and the service life will be shortened. High, good for the operation and use of the electric furnace.

High-temperature muffle furnace electric furnace wire has anti-maintenance treatment during the production process, but due to various reasons such as transportation and installation, the electric furnace wire may be more or less damaged before use. At this time, the electric furnace wire can be pre-oxidized For treatment, the electric furnace wire equipment is energized in dry air until the upper limit temperature can be reached and the operating temperature is lowered between 100 ℃ and 200 ℃, and the temperature is maintained for 5 to 10 hours and then slowly cooled.
