High Temperature Industrial Furnace Heating Elements Mosi2 Heaters
Industrial Furnace Heating Elements introduction :
1. Mosi2 heating element is a kind of resistance heating element with high temperature resistance, oxidation resistance and low aging based on molybdenum disilicide.When used in high temperature oxidation atmosphere, a layer of bright and compact quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of si-mo rod from oxidation, so the element of si-mo rod has unique high temperature oxidation resistance.
High temperature oxidation resistance:
When MoSi2 elements are used at high temperature and under oxidation circumstance, a dense layer of quartz (SiO2) is generated on the surface of the element to prevent it from further oxidation.
When the temperature of element is over 1700ºC, the SiO2 protecting film whose melting point is 1710ºC will be melted. Due to its surface tension, SiO2 agglomerate() into drops and lose protection. The SiO2 protecting film is formed again when the element continues to be used under the oxidation circumstance.
It must be pointed out is that the MoSi2 heating element cannot be used in the temperature between 400ºC to 700 ºC for long time. Otherwise, the element will be pulverized because of the strong low-temperature oxidation.
Industrial Furnace Heating Elements Replacement
If there is a damaged part found in the process of operation, the first thing you should do is determine its location and get all the combination elements ready. After that, you should separate the wire the damaged element clipped to from the screw which is connected to the generatrix. Then remove the remained refractory wool and pull out the refractory stoppers. Insert the new combination elements into the furnace from its roof. Connect all the wires and get the refractory wool filled, and finally raise the temperature.
