How to prolong the service life of molybdenum rod？The temperature on the surface of the molybdenum rod is higher，it is recommended to use as little as possible surface load density. Please note that when the cold end of the value of the silicon carbide in the air of 1000 degrees, the current, voltage don’t necessarily match with the actual use.

Continuous use of molybdenum rods can increase the resistance and maintain a long life. If the resistance of the resistor is higher, the resistance of the molybdenum rod is higher, which leads to the rapid increase of the resistance and the shorter life.

Temperature distribution characteristics of the molybdenum rod, checking the specifications of the new shipment effective heating length of 60 degrees Celsius or less qualified, of course, its aging temperature distribution becomes larger, and may eventually reach 200 degrees Celsius. The specific temperature distribution changes, due to the furnace atmosphere, it can use different conditions.

The longer the life of the molybdenum rod, the higher the temperature, the temperature of the furnace is more than 1400 degrees in a short period, the oxidation rate is fast, the life is short, pay attention to the use of molybdenum rod surface temperature.
