Comparative analysis of the advantages and disadvantages of graphite heating and silicon molybdenum rod heating under the condition of long-term working temperature of 1750 degree vacuum
The heating temperature is generally higher than the working temperature of 200 DEG C according to the calculation, such as the title, heating the working temperature of 1950 degrees Celsius
The maximum working temperature of MoSi2 heating material is 1700 DEG c,
Graphite heater (rod, tube, plate) in the absence of air in the working temperature of up to 2500 degrees C.
Temperature is not the most important factor, the actual long-term working temperature is about 1600 degrees
Contact with oxygen in the air, graphite heater easy oxidation, The workpiece will be placed in the high temperature ceramic tube, not directly contact with graphite.
