1. Resistance properties

The resistivity of element rapidly rises along with the temperature rises,under normal operating conditions,generally the element resistance doesn’t change with the application time changing. So the old and new elements can be used together.

2. Surface load

The key factor to the optimum service life of the element is to select the surface load of the element correctly according to the furnace construction,atmosphere and temperature.Right figure shows the relation between the furnace temperature,the element temperature and the element surface load under the condition that element radiation isn’t obstructed.The shadow part in the figure shows the surface load--temperature range in common use.The figure still shows the reference current.
