Chemical property
 
Ant-oxidation in high temperature atmosphere: When MoSi2 bar is used in the high temperature and oxidative atmosphere; it will form a compact SiO2 protecting film in its surface to prevent its continuing oxidized. When the temperature of element is over 1700℃,the SiO2 protecting film whose melting point is 1710℃ will be melted. Due to the 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 oxidative atmosphere.
It must be pointed out is that the MoSi2 heating element can not be used in the temperature between 400℃ to 700 ℃ for long time. Otherwise, the element will be pulverized because of the low-temperature oxidation.

Resistance characters
 
MoSi2 elements have good resistance characteristic. This is the deciding factor that it can replace conventional heating elements to be an ideal heating material. Its resistivity is very low in the greenhouse. As the temperature rises, the resistivity increases rapidly. Therefore, it is self-evident that the product has rapid temperature increment and low power expenditure. In normal operating circumstances, the elements resistances is not changing along with the length of time changes ,so the old and new elements can be mixed.
 
Product use and maintenance
1. MoSi2 heating elements belong to Metal ceramic material. They are hard, crisp and low impact strength at room temperature .Therefore to be careful to avoid damage during transport and installation.
2. When MoSi2 elements continue use under the oxidative atmosphere, the surface temperature of 1700 type should not exceed 1700 ° C,1800-type should not over 1800 ℃ and when intermittent use,1700 type-element should not over 1650 ° C,1800type-element can not exceed 1750 ℃.
3. The MoSi2 heating element should avoid using in the temperature between 400℃ to 700 ℃ for long time. Otherwise, the element will be low-temperature oxidized because of the adverse temperature condition.
 
 
Furnace dryness
New or old furnace not used for a long time needs to be dry before the use. Generally, the drying temperature is 100-200℃.However, if the element is used for a long time under the low temperature, it will cause the low-temperature oxidation. For the little furnace, the drying time is short, so the influence of several drying hours is little, but the large furnace need to be dry for a long time, you had better open the furnace door to ventilate well. you can open the furnace door ajar with the temperature increment and completely close until the temperature reach 1000℃ above.
 
Furnace start
If the furnace dry out has been completed or does not need drying, it has to rise its temperature. In order to avoid the over sized electric current impact and cause the electrical equipment overload; please go up the furnace temperature according to the next table.
 
Small furnace (power100KW) Large furnace(Power 100-500KW)
Furnace temperature Voltage furnace temperature℃ Voltage
20-150 1/3Operating Voltage 200-300 1/3Operating Voltage
150-500 2/3Operating Voltage 300-700 2/3Operating Voltage
500-operating temperature The Whole-Operating Voltage 700-Operating temperature The whole-Operating Voltage
 
It should not take a long time when shifting gears. Otherwise it easily causes the electric current shocking to break the electrical equipment.
 
Element 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.
