silicon molybdenum rod Introduction¡êo
The resistance-resistance electric heating element is a kind of resistance heating element with high temperature resistance and oxidation resistance based on molybdenum disilicate.When used in high temperature oxidizing atmosphere, a bright and dense silica (SiO2) glass film is generated on the surface, which can protect the inner layer of si-mo rod from oxidation. Therefore, si-mo rod element has unique high temperature oxidation resistance.
In the oxidizing atmosphere and the operating temperature is 1800℃, the resistance of the silicon-molybdenum rod heating element increases rapidly with the temperature rising, and the resistance value is stable when the temperature is constant.Under normal circumstances, the resistance of the element does not change with the length of service, so the old and new silicon-molybdenum rod heating elements can be mixed.
According to the structure, working atmosphere and temperature of the heating equipment, it is the key to choose the surface load of the heating element correctly.
