Yuhao MoSi2 Heating Elements: Electric Property
1. Resistance Property
The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, generally the element resistance doesn’t change with the service life changing, so the old elements can be mixed used.
2. Surface Load
According to the structure, the temperature and atmosphere in the correct choice of components surface load is the key element to the highest life. The picture shows that the relation among the furnace temperature, the element temperature and surface load under the circumstance that the thermal radiation component is uncrossed. The shaded part is for common surface load - the temperature range.
